evenly distributed, and changed the implementation of
create_blender_table() to create a more evenly distributed distribution of
the lower 2 bits. It should be faster as well.

grabber.
3.9.32: many bugfixes from various people.
3.9.32: zipup.sh now generates dependencies entirely using standard Unix
tools and gcc, so it can setup all the supported platforms without
needing those compilers to be available (ie. I can create Watcom, BeOS,
and Mingw32 dependencies all from my Linux machine). This does require a
bit of cooperation from the different targets, though: they have to set
up their "make depend" target to override the standard gcc defines, and
wrap any non-standard header includes with "#ifndef SCAN_DEPEND".
3.9.32: fixed (I hope :-) bug with non-GMT timezones in the datafile
update code.
3.9.32: rewrote the Unicode usprintf() to piggyback on libc when
converting floating point data (too hard to get this right ourselves :-)
3.9.31: Henrik Stokseth did some work on a native Mingw32 build. This is
currently incomplete, and unlikely to work right now since there have
been other changes in the Windows code since the version he started from.
At the moment this version is statically linked, using makefile.mgs, and
makefile.mgw still exists for the MSVC-piggyback version. The ultimate
goal is to get this native version building as a DLL in addition to
statically linked, at which point we can merge both makefiles into
makefile.mgw and remove makefile.mgs. Oh yeah, and there are currently no
docs for the native version.
3.9.31: Greg Hackmann contributed a Borland C++ Builder port. Like the
RSXNT and Mingw32 versions, this is a client for the MSVC DLL, and not
able to compile Allegro directly itself, but allows you to build Allegro
programs using the Borland compiler.
3.9.31: Robert Ohannessian added MMX optimisation for the 8 and 16 bit
clear() functions, and Jose Antonio Luque optimised the 16 bit blit() and
masked_blit() routines.
3.9.31: Vincent Penquerc'h added a yield_timeslice() function (currently
implemented in DOS and Unix).
3.9.31: added a desktop_color_depth() function (currently only
implemented in X: a Windows version will follow).
3.9.31: Isaac Cruz added support for windowed modes in color depths other
than the current Windows desktop, and hardware accelerated system bitmaps.
3.9.31: Jose Antonio Luque improved the Windows joystick driver.
3.9.31: James Hyman added support for dithering truecolor down to
paletted images.
3.9.31: Chris La Mantia added textout_right(), textprintf_right(), and
textprintf_justify() functions.
3.9.31: Sven Sandberg added a ustrrchr() function, and improved the
usprintf() handling of large floating point values.
3.9.31: Peter Pavlovic added a Slovak keyboard mapping and message
translation.
3.9.31: Manni Heumann fixed some problems with the German keyboard
mapping.
3.9.31: Michael Bukin improved the X keyboard and mouse handling, and
fixed some problems with building on non-GNU Unix systems.

patience has run out so you don't get a full list :-)
3.9.31: Peter Wang added input support to the Linux OSS sound driver.
3.9.31: David Kuhling optimised the i386/gcc fsqrt() code, and added an
fhypot() routine.
3.9.30: fixed the double XOR that was making datafile passwords so easy
to reverse. The new code can still read old-style encrypted files, but
data written by this version can't be accessed by older copies of Allegro.
3.9.30: made load_datafile(), load_datafile_object(), and the
file.dat#object syntax work correctly in all possible combinations.
3.9.30: Vincent Penquerc'h added a scare_mouse_area() function.
3.9.30: changed the DirectX surface locking mechanism, to improve the
performance of hardware accelerated drawing.
3.9.30: George Foot improved the Linux LED code, and made the internal X
driver state visible via xalleg.h.
3.9.30: added EINTR retry handling to read/write calls. I hope I got this
right: if anyone who properly groks this stuff could check over file.c,
that would be cool.
3.9.30: made the Windows mouse driver work correctly in windowed mode.
3.9.30: fixed various problems with Windows foreground/background
switching (keys were getting stuck down, timers weren't being paused, and
not all the right switching modes were being reported to the caller).
3.9.30: made the X keyboard handler release all keys when it loses the
input focus, to avoid stuck buttons when you alt+tab between windows.
3.9.30: made the allegro-lib script arguments compatible with the
standard used by GTK, ESD, etc, and renamed it to allegro-config. This
changes the syntax for linking Allegro programs on Unix: see readme.uni
for details of the new method.
3.9.30: George Foot improved the Unix shared library system.
3.9.30: Joerg Rueppel added a find_datafile_object() function.
3.9.30: Peter Wang improved the SVGAlib driver.

3.9.29: made the Windows code agree with other platforms about how video
bitmaps are supposed to behave.
3.9.29: fixed some problems with the Windows mouse wheel support.
3.9.29: added set_write_alpha_blender(), set_add_blender() and
create_blender_table() functions, and made the 32 bit version of
draw_trans_sprite() able to use 8 bit source images in conjunction with
set_write_alpha_blender(). In addition to being generally useful, using
these routines makes the sources for my SpeedHack entry much smaller :-)
3.9.29: added uninstall targets to the Linux makefile.
3.9.29: made the X windowed mouse driver hide the Allegro cursor when the
mouse moves out of our window.
3.9.29: added a simple timer delay emulation of vsync() to the X code, so
that eg. the demo worms game runs sensibly.
3.9.29: Isaac Cruz added a GFX_DIRECTX_WIN driver.
3.9.29: Keith Gerdes made some more improvements to the DirectX overlay
driver.

d_list_proc() use it.
3.9.29: Lucas Vignoli Reis added a Portuguese (Brazil) message
translation and keyboard mapping.
3.9.29: Peter Wang added a Linux OSS MIDI driver for FM synth devices,
and mixer support for the OSS digital driver.
3.9.29: George Foot added scripts for building various Linux distribution
formats.
3.9.29: Michael Bukin fixed the portability problems in quantize.c.
3.9.29: added a zipwin.sh script for making Windows binary distributions,
including a batch file that can compile the MSVC support programs without
having any GNU tools installed.
3.9.29: fixed bug with color font rendering in the Windows version.
3.9.29: added hardware accelerated rectfill() and hline() to the Windows
version, and fixed a couple of accel related bugs (clears were being
clipped wrongly, and it was claiming to support XOR drawing even though
that isn't supported).
3.9.29: Michael Bukin fixed bug with X drawing onto screen sub-bitmaps.
3.9.28: various documentation updates.
3.9.28: added parameter autodetection to the Unix OSS sound driver.
3.9.28: made it possible to nest calls to the Unix for_each_file()
routine.
3.9.28: added a load_datafile_callback() function.
3.9.28: rationalised the sound config variables, so they can be shared
between drivers more easily. For instance sb_freq has been renamed to
sound_freq.
3.9.28: Antti Koskipaa added a DOS driver for WSS (Windows Sound System)
cards.
3.9.28: the audiosteam code is now able to merge multiple buffers into a
single larger one, so it will still work correctly even if the user
supplies a buffer smaller than the current soundcard transfer size. You
can even play streams with single byte buffers now, as long as you refill
them often enough!
3.9.28: made the Windows timer code more robust, so it will no longer
lock up when you install extremely high frequency callbacks.
3.9.28: Teijo Hakala added wheel support to the Windows mouse driver.
3.9.28: Peter Wang added wheel support to the X mouse driver.
3.9.28: Andrew Geers added -ppassword and -nosound options to the grabber.

bitmaps of DirectDraw surfaces.
3.9.28: Peter Wang added banked mode support to the SVGAlib driver.
3.9.28: Peter Wang fixed some problems with the ESD sound driver, and
added an ALSA driver.
3.9.28: palette fading speed is now timer regulated, to avoid problems
with some systems (eg. DGA with non-matching color depth) where it can be
excessively slow.
3.9.28: fixed a couple of different overflow bugs that were causing
timers to run slow on heavily loaded Unix systems.
3.9.28: added a display of author credits to the demo game.
3.9.28: changed the info page installation system. It now creates a dir
file in the same directory as the info page, rather than messing around
with symlinks, and autoconf is used to locate the install-info program.
3.9.28: added an allegro-lib script to the Unix installation, which can
be run by makefiles to find the right linker commandline for building
Allegro programs.
3.9.28: added a manpage output format to the makedoc utility. It doesn't
work terribly well with apropos due to the lack of a one-line summary for
each function, but the basic formatting seems to be ok: please let me
know if you see any problems.
3.9.28: patches from George Foot for Linux console handing, keyboard, and
filename manipulations.
3.9.28: many improvements by Michael Bukin, in particular enhanced
performance in X, better X mouse behaviour, and DGA graphics support.
3.9.27: Robert J. Ragno made some improvements to the Wingman, PSX, and
throttle joystick input code.
3.9.27: Peter Wang added wheel input support to the Linux mouse code
(this shows up as a new mouse_z state variable).
3.9.27: Patrick Hogan made Windows audiostreams work properly.
3.9.27: Sven Sandberg optimised the spline routines.
3.9.27: Tomohiko Sugiura added KEY_YEN and KEY_YEN2 Japanese keys to the
input handler.
3.9.27: Chris Robinson wrote a fixed point version of clip3d_f(), called
(surprise!) clip3d().
3.9.27: Sven Sandberg improved the file selector sorting algorithm.
3.9.27: Henrik Stokseth improved the OS detection in the Windows lib.
3.9.27: Sven Sandberg made more accurately rounded lookup tables for the
fixed point trig routines.
3.9.27: George Foot made the fbcon driver reset the palette on exit.
3.9.27: much new X code from Michael Bukin: this stuff is working
brilliantly now!
3.9.27: added the X library path to the Linux liballeg.a wrapper. I think
I prefer Michael's idea of having a script to return this info, though,
so perhaps we should change across to doing it that way.
3.9.27: fixed various bugs in both the C and i386 RLE sprite code (mostly
relating to lit modes and hicolor formats).
3.9.27: front-ported various fixes from the 3.12 release, to make
WARNMODE=1 compile cleanly with gcc 2.95.
3.9.27: Knut Pape improved the Mingw32 readme file.
3.9.26: rewrote the DOS Sidewinder driver, after powerjaw sent me a pad
to test it with. It still doesn't work for me in DOS mode, but it is ok
under Windows, which is better than before, and as good as any of the
other Sidewinder code that I've been able to locate. If anyone has or
knows of code that works better than this, please let me know!
3.9.26: more flexible mode flags for set_color_conversion().
3.9.26: Robert J. Ragno added a driver for Gravis GrIP devices.
3.9.26: Gorka Olaizola added a Redhat RPM .spec file.
3.9.26: Stepan Roh updated the Czech translation and added multiple
codepage support to the textconv utility, and a Unicode-aware ustrtod()
function.
3.9.26: added ustrdup() to the Unicode support functions.
3.9.26: Sven Sandberg optimised the gcc fixed point math routines to
collapse constant expressions at compile time.
3.9.26: Stefan T. Boettner added a proper Linux SVGAlib driver.
3.9.26: several tweaks from Vincent Penquerc'h (added a datafile merge
function to the grabber, GUI bugfixes, optimised spline calculation, fix
for 24 bit version of the C drawing code).
3.9.26: Linux patches from Michael Bukin improve the OSS sound driver,
SIGALRM handling, and X keyboard driver.
3.9.26: many Linux patches from George Foot (fixes to the mouse driver,
shared library and configure script, and assorted other stuff).
3.9.25: fixed pckeys.c to leave sensible data in the key[] array when
doing numeral vs. arrow key numlock fakery.
3.9.25: fixed a bunch of problems with the SWITCH_BACKGROUND mode (I'd
stupidly forgotten to disable a lot of graphics driver functions that
could do bad things if called when the Allegro console isn't active).
3.9.25: added pivot_sprite() and pivot_scaled_sprite() functions (thanks
to Matt Jallo for the suggestion).
3.9.25: added ustrerror() to the standard Unicode support functions.
3.9.25: fixed the d_edit_proc() GUI object to handle shift+tab focus
movement properly.
3.9.25: lots of Linux patches from George Foot (proper fbcon mode
setting, different mouse types and setup program support for configuring
them, fixes to the shared library support, exedat no longer destroys the
file permissions, and probably some other stuff that I forgot about).
3.9.24: assorted bugfixes to the Linux fbcon and sound code (this is
mostly an emergency release because these were broken in 3.9.23).
3.9.24: James Arthur wrote some docs for the Photoshop-style truecolor
blender routines.
3.9.23: Michael Bukin added an OSS sound driver to the Linux code, and
the beginnings of an ESD driver.
3.9.23: many Linux patches from George Foot, including shared library
support.
3.9.23: Ole Laursen made the Unicode utolower() and utoupper() functions
understand the entire 16 bit character set.
3.9.23: Pavlos Touboulidis made file_select() able to include or exclude
files based on their attributes.
3.9.23: the d_check_proc() GUI object can now print the text to the right
of the check, selected by having a non-zero d1 field.
3.9.23: changed my mind about how GFX_SAFE should work, and removed the
color depth emulation bodges. Now, the GFX_SAFE driver may simply change
the color depth if it doesn't like what you are requesting, and it is up
to the caller to deal with this.
3.9.23: fixed problems with MMX polygon rendering code in the MSVC
version.
3.9.23: added a strictwarn option to the configure script, and fixed
everything that it moaned about. The warnings still aren't all that
strict: at some point I want to sit down and make it build cleanly with
-W, as well as -Wall -Werror.
3.9.22: fixed some potential race conditions introduced by my previous
fixes to the Windows timer code.
3.9.22: made set_display_switch_callback() able to install multiple hook
functions, added a remove_display_switch_callback() routine, and wrote an
exswitch example program.
3.9.22: adjusted MSVC inline asm syntax in an attempt to work around
compiler version conflicts.
3.9.22: more flexible GFX_SAFE system. As well as defining fixed safe
values for each platform, you can now leave out those definitions to get
zeros passed through to the actual hardware drivers, and if your driver
sets a color depth other than the requested one, graphics.c will hook up
some emulation routines so that everything still works in a sensible way.
3.9.22: George Foot added a scancode to ASCII conversion function to the
keyboard driver (implemented for DOS, Windows, Linux, and X). This is
needed to handle alt+key input sensibly when using unusual mappings like
the Dvorak layout.
3.9.22: Linux patches from George add better console switching, shared
library support, and various other nice things.
3.9.22: Windows patch from Stefan adds much cool new stuff, including
windowed mode support.
3.9.22: Peter Wang made the Linux GGI driver work properly.
3.9.22: Johan Venter made some more improvements to the RSXNT and Mingw32
makefiles.
3.9.22: updated the Watcom makefile to allow manual override of the 10.6
vs. 11.0 version detection, in case it guesses wrong.
3.9.21: Windows patch from Stefan adds support for the new screen mode
switching system.
3.9.21: more BeOS patches from Jason Wilkins.
3.9.21: Johan Venter fixed some problems with the RSXNT and Mingw32
makefiles.
3.9.21: ran "configure --enable-asm=no", and fixed all the reasons why
this didn't work. In particular there was a bug in patterned drawing
modes, RLE sprites were broken, and I'd forgotten to add C versions of
the RGBA sprite functions. Those of you who are interested in such things
will be interested to know that the test program thinks the C drawing
code is 20% slower at hline(), 10% slower at rectfill(), 50% slower at
blitting, and 40% slower at draw_sprite(), which is not at all bad going.
It's actually a bit faster at drawing translucent and lit sprites, so we
need to have a look at that!
3.9.21: many new Linux patches from George Foot.
3.9.21: added VBE/AF support to the Linux code.
3.9.21: finished the Linux fbcon driver.
3.9.21: made Linux console switching work in a more complete manner, with
a set of helper functions in dispsw.c. The background mode should work
now, but is untested.
3.9.21: added Linux GGI driver by Carsten Schmidt (this is somewhat out
of date, and doesn't work yet, but a good start if anyone wants to hack
on it).
3.9.21: improved the Unix configure and build system. Moved more things
into makefile.lst, so there are no file lists anywhere else now. Made it
understand how to build the datafile tools, and convert the documentation
(this may cause problems for systems without makeinfo: it would be good
if someone who groks autoconf could try to do this better). Made the
Linux VGA drivers (vga and modex) configurable.
3.9.21: added ctrl+alt+end abort sequence to the Linux keyboard driver.
3.9.21: directory structure changes: moved ufile.c into the misc
directory, so BeOS can share it. Moved various helper scripts into the
misc directory, including a cmplog.pl that compares two test.exe profile
logs.
3.9.21: made the Linux PS2 mouse driver understand the middle button.
Added a scaling factor to make it go at a more sensible speed in SVGA
modes.
3.9.20: started working on a driver for the Linux fbcon device. It works,
but can't change video mode yet.
3.9.20: Windows patch from Stefan adds joystick input, and the beginnings
of a windowed mode driver.
3.9.20: moved all filename lists (even the platform specific ones) into
makefile.lst, to avoid any duplication and give us a nice centralised
place that mentions every single source file we use.
3.9.20: removed the install_lost_bitmap_callback() function, in favour of
the more generic set_display_switch_mode(). Updated the Windows code to
use these new routines.
3.9.20: merged X patch from Michael Bukin (adds mouse support).
3.9.20: Vincent Penquerc'h optimised the 256 to truecolor graphics
blitting code to avoid repeated conversions of the palette table.
3.9.20: James Hyman added quoting support to get_config_argv().
3.9.20: Peter Cech optimised the alpha sprite blending routines. Shawn
optimised them a bit more by expanding out specialised versions for
common pixel formats.
3.9.20: Richard Davies made some improvements to the PSX joypad driver.
3.9.20: added a system driver parameter to allegro.cfg, and hooks to make
the Unix version look for config data in /etc/ and ~/.
3.9.20: moved the Posix findfirst() emulation into libc.c, removing it
from the autoconf and BeOS specific builds.
3.9.20: more BeOS patches from Jason Wilkins. The graphics stuff be
working there now!
3.9.20: improved the VBE/AF driver to know that vertical lines can be
implemented as a rectfill. This enables hardware acceleration for
patterned vertical lines, and with drivers that don't have hardware
support for the VBE/AF line draw routine.
3.9.20: George Foot did some major work on the Linux console version,
getting it up and running in a fairly convincing way.
3.9.20: the Windows sound driver lists are now dynamically generated
based on the available devices, so you can select which ones to use.
3.9.19: wrote the first part of an Allegro Hacker's Guide, which is my
(probably futile :-) attempt to document at least a few of the more gory
parts of the Allegro code.
3.9.19: finally got around to documenting the Unicode functions.
3.9.19: more BeOS patches from Jason Wilkins.
3.9.19: Michael Bukin made some more patches to the X code (timers are
implemented now), and added a complete (?) C implementation of all the
drawing code. Non-Intel machines, here we come! If you define
ALLEGRO_USE_C before building the djgpp library, you can actually test
out a pure C version of test.exe, the demo game, etc.
3.9.19: added a findtext.sh script, which scans the source code and
creates a list of all the strings that are available for translation. It
can also compare this list against an existing translation file, to see
if any new messages need to be added.
3.9.19: Stepan Roh updated the Czech keyboard mapping for Unicode
support, added support for keyconf to use a non-standard font, and added
the Latin Extended-A characters (U+0100 to U+017F) to the default font.
3.9.19: Grzegorz Adam Hankiewicz updated the Spanish translation with
UTF-8 format (ie. properly accented) strings. Converted the setup program
font into Latin-1 ordering so that this will display correctly. Fixed bug
with dat2s not correctly converting the resulting multiple-range font.
3.9.19: Chris La Mantia made some cosmetic fixes to the d_slider_proc()
GUI object.
3.9.19: Richard Davies added support for N64 joypads.
3.9.19: added keyboard_ucallback() (I missed this one when I first added
the Unicode support).
3.9.19: made some changes to setup.c so that it can easily be embedded
into other programs (thanks to Grzegorz Adam Hankiewicz for the
suggestion).
3.9.18: added support for 32 bit RGBA images. You can now read TGA files
with an alpha channel into the grabber, or you can import a normal image
and then overlay alpha data from any greyscale bitmap. You can save these
alpha channels as part of a datafile, call the makeacol(r, g, b, a)
function, and most importantly, call set_alpha_blender() and then
draw_trans_sprite() to display them. Check out exalpha.c. There is much
room to optimise the 15, 16, and 24 bit versions of _blender_alpha*(), if
anyone wants to have a go at this. I think it would be profitable to
write specific versions for common pixel orderings, and only keep the
current generic implementation around as an emergency fallback.
3.9.18: more Unix patches from Michael Bukin. It builds flawlessly now,
even if it doesn't do anything very interesting yet.
3.9.18: Jason Wilkins contributed the beginnings of a BeOS port (not yet
functional, but it does compile).
3.9.18: Revin Guillen added a position_dialog() function.
3.9.18: portability improvements: changed makefile to be a generated
stub, which normally just includes makefile.all, but can be completely
replaced when using autoconf, and moved the emulation for missing libc
functions into the shared sources.
3.9.18: numerous bugfixes.
3.9.17: Burton Radons changed the truecolor pixel blending functions to
use a single callback function rather than the previous table. This may
break some old code, but should remain largely backward compatible, and
the new way is much more flexible. He also added a more complete set of
blender functions, including Photoshop modes like burn, difference,
lumincance, etc.
3.9.17: Richard Davies added support for PSX joypads.
3.9.17: fixed bug in dat2s handling of truecolor images.
3.9.17: Jason Wilkins improved the quaternion math routines, and added
some documentation for them.
3.9.17: Neil Townsend added callback parameters to the timer handlers.
3.9.17: Gunter Ladwig added three-button mouse emulation, which can be
enabled using the config file (it defaults to on if you have a two button
mouse).
3.9.16: applied some patches from Michael Bukin, which add the basics of
a Unix build system. It doesn't actually work yet, though :-)
3.9.16: merged new code from Stefan. Lots more cool things are working in
the Windows version now, eg. hardware acceleration, triple buffering,
sound...
3.9.16: added an example of how to write a Windows screensaver using
Allegro. If anyone knows how to get a proper name to show up in the
Windows selection dialog, please let me know! (I've made the stringtable
entry that MSDN says you need, but it doesn't work).
3.9.16: Andy Goth added a d_text_list_proc() dialog object, that lets you
alter the selection by typing the first few characters of a list entry.
3.9.16: Ole Laursen updated the Danish message translation.
3.9.16: Calvin French added a -w (always update) switch to dat.exe.
3.9.16: Joerg Rueppel added more flexible wildcard matching for object
names in dat.exe.
3.9.16: added GFX_HW_SYS_TO_VRAM_BLIT and GFX_HW_SYS_TO_VRAM_BLIT_MASKED
capabilities flags, and more flexible blitting functions in the vtable.
3.9.16: added lock_voice() and unlock_voice() methods to the digital
sound driver, for implementing audiostreams under Windows.
3.9.16: _handle_timer_tick() now returns the desired gap until the next
interrupt.
3.9.15: Michael Rickmann added a Mingw32 port. This currently works the
same way as the RSXNT version, using MSVC to build the DLL, but will
become a full gcc port after the core Windows code stabilises a bit.
3.9.15: Vincent Penquerc'h added a D_DIRTY flag for GUI objects, and I
extended this with a new D_REDRAWME return code for the handlers.
3.9.15: changed the syntax of the create_color_table() callback. This
breaks the API, but is the only way to make it work reliably with
different compiler calling conventions.
3.9.15: added a sub bitmap creation hooks to the vtable structure (so the
parent bitmap can be told when it is being cloned).
3.9.15: "make install" is now a separate target, not run automatically.
This means that you now have to run "make" and "make install" as two
separate operations, or if you want all three versions of the library,
"make all" and then "make installall".
3.9.15: added an END_OF_MAIN() macro, which makes the WinMain() magic
work correctly in any combination of C and C++ code.
3.9.15: Olly Betts modified the djgpp makefile to support cross-compiling
on a Linux machine.
3.9.15: Andy Goth added a 256x256 tweaked VGA mode.
3.9.15: major documentation update (from now on I'll be adding a version
number to each changelog comment).
Merged new code from Stefan. Windows version is getting much closer to
completion, including mouse support and video bitmaps, although the mouse
code isn't working quite right for me at the moment.
Rewrote fix_filename_path() to avoid calling _fixpath(). The new version
is much more portable, although things like reading the current directory
across multiple drives need some tweaking to work with different
compilers.
Fixed oodles of things that were stopping the Watcom version from
working. It now runs everything without any trouble at all, including
such gems as exdodgy and the grabber shell edit! According to test.exe,
gcc 2.8.1 is about 10% faster than Watcom 10.6 for most things, although
for some reason textout() is about twice as fast in the Watcom version.
Fixed a bunch of stuff to make the RSXNT version work. All the tests and
examples now build with RSXNT, and work identically to the MSVC originals.
Added quaternion math routines by Jason Wilkins.
Added more flexible gfx_card config support by Andy Goth.
Added a masked_stretch_blit() function (trivial change, the code could do
it, but the API entry point was missing).
Added Windows GDI routines by Marian Dvorsky.
Added a DMA poll to the Soundscape driver, to make sure it can never get
out of sync with the transfer.
Merged various bits and pieces that have been sitting around my hard
drive for ages (Swedish and Norwegian translations, various patches from
Michael Bukin, new palette generation code by Michal Mertl, Soundscape
driver fixes by Andreas Kluge).
Grabber now knows about and can manipulate Unicode fonts.
Now passing atexit() as a parameter to install_allegro(), to avoid
problems with DLL shutdown.
Made FLIC player set the dirty variables when clearing the bitmap at the
start/loop point (this was sometimes causing the screen not to be cleared
from previous contents).
Fixed several bugs in the grabber.
Changed the datafile utilities to link the datedit and plugin routines as
a proper library. This will make life easier for third parties that want
to use those routines (duplicating the plugin linkage isn't much fun).
Replaced errno references with allegro_errno pointer, to avoid problems
with multiple runtimes when linking as a DLL. The MSVC version of dat now
works perfectly!
Added a system_none driver for commandline utilities and other platform
neutral situations.
Made new demo intro animation. My first ever Max rendering!
Merged Windows patches from Stefan. Whoah! This thing is cool. It works
(sort of :-) on two platforms. Now I can die happy....
The file selector now adjusts for platforms without any directory list
(eg. Unix).
Added a global default_palette (the normal IBM BIOS one), and made
set_gfx_mode() select it.
Modified DIGMID driver to avoid using 64 bit ints or floating point in
the interrupt handler.
Added ASSERT() and TRACE() debugging routines, and lots of asserts
throughout the library code.
The default truecolor pixel format before setting a video mode is now BGR
rather than RGB. This should help to shake out bugs in BGR support, and
catch any errors where people load graphics before setting a video mode.
Fixed fmul() overflow detection bug.
Rewrote gpro.c and sw.c to avoid using inline asm. The SW code is
currently very ugly (literal translation of the asm routine), but I'm
keen to improve it given some testing feedback. If you have a Gamepad Pro
or Sidewinder, and were able to use it with the Allegro 3.11 driver, I
would _really_ like to hear whether this current code works for you or
not...
Numerous changes to make the support programs more portable.
Added a get_executable_name() function.
The sound.cfg file is no longer supported. Use allegro.cfg instead.
Added versions of the inline _putpixel() and _getpixel() for all color
depths.
The check_cpu() function is now called automatically by allegro_init().
Added system bitmap objects, which exist in system memory but are
accessed in a similar way to video memory surfaces (this can enable
better hardware acceleration on some platforms).
Added enable_triple_buffer(), timer_can_simulate_retrace(), and
timer_is_using_retrace() functions. This enables programs to correctly
handle the interrelationship between mode-X triple buffering, the retrace
sync mode, and the current OS, without having to include any DOS specific
code.
GUI routines now call the input polling functions and acquire/release the
screen as appropriate.
Fixed a real show-stopping error that was causing VBE/AF crashes on some
machines (calling driver functions with non-flat memory selector in %es).
Added an allegro_message() function.
Added dummy bank switch routines that can emulate linear access to a
mode-X screen, albeit rather slowly. The only practical result from this
is that polygon routines work in mode-X now, but it helps to make things
more robust in general (if a routine doesn't know about mode-X, now it
will just run more slowly than usual, rather than not working at all).
The SB, Adlib, and standard joystick drivers now properly have a separate
instance for each variant of the hardware, rather than a single driver
pretending to exist under multiple different ID codes.
Rewrote joystick polling to avoid inline asm.
Converted translation files into UTF-8 format. These can now use any
Unicode characters they like, so accented vowels etc. can safely be used.
Keyboard scancodes have changed from the hardware format to an abstract,
Allegro-specific encoding. This simplifies the code a great deal, and
avoids hassles with two different keys generating the same scancode.
Added generic find_allegro_resource() function, which removes a lot of
duplicated code from config.c, digmid.c, and pckeys.c.
Timer module now autoinstalls whenever someone tries to use it.
Keyboard functions can now alter the repeat rate.
Watcom port.
Added a special GFX_SAFE driver ID.
Now using VDS to detect win95 even when in stealth mode.
Added fixver.sh for patching version numbers and dates when releasing a
new version (requires bash, fileutils, shutils, etc, to run on DOS).
Added zipup.sh for building a distribution zip and diffs, which
automatically cleans up the tree ready for this (eg. pregenerating the
dependency files for all supported compilers).
Added input polling functions.
Major code restucturing, added system drivers, new framework for input
handling, timers, keyboard scancode conversion, file access, etc.
Added full support for Unicode text, including string manipulation
functions, a new font format, the textconv utility, a new GUI MSG_UCHAR,
and a ureadkey() function.
Added variable sized monochrome fonts, replacing the the old 8x8 fixed
size format. As a result, the GFX_HW_TEXTOUT_FIXED capabilities flag has
been renamed to GFX_HW_GLYPH.
New system for accessing video memory, using bmp_select(), bmp_write*(),
and bmp_unwrite_line(). This is equivalent to the djgpp farptr functions,
but portable to different platforms.
Drastic reorganisation of directory structure, makefile system, etc.
Enhanced the makedoc utility to simplify adding links and email addresses
to the docs.
Added a bodge to make the VESA code work with broken S3 Trio64 drivers.
Removed the 386DX vs. 386SX processor detection code (it was sometimes
crashing).
==============================================================
============ Changes from 3.11 to 3.12 (Aug 1999) ============
==============================================================
Fixed a few incompatibilities with gcc 2.95. This release is otherwise
identical to 3.11.
=============================================================
============ Changes from 3.1 to 3.11 (Feb 1999) ============
=============================================================
Cleaned up a few places where memory wasn't getting freed during the
system shutdown. A cosmetic detail since the OS will free it for us, but
it is nice to get these things right.
Alessandro Monopoli added an Italian translation of the system messages.
Henrik Stokseth added code to distinguish between win95 and win98.
Creative Labs have been removed from the THANKS file, because of their
refusal to release any specs on the SB Live soundcard.
Changed the name of the library. After years of thinking that Allegro was
a word with no particular meaning, I realised that it is in fact a
recursive acronym for "Allegro Low Level Game Routines".
Established a new mailing list for use by the people currently working on
Allegro. Please send code contributions to this list rather than directly
to me (Shawn Hargreaves), because this will allow Allegro development to
continue even if I'm not around or am busy with something else at the
moment.
Andreas Kluge wrote a driver for Ensoniq Soundscape cards.
More localisation: Swedish message translation by Sven Sandberg, Anton
Ragnarsson, and Erik Sandberg, Finnish message translation by Antti
Haapala, and Russian message translation and keyboard mapping by Dmitriy
Kazimirow.
The midi_out() function now correctly updates the pan/volume/bend
controller status.
Kester Maddock added a Wingman Warrior joystick driver.
Fixed some problems with the Sidewinder, Gamepad Pro, and SNES joypad
drivers.
Changed the SB16 driver to use signed 16 bit output mode, rather than the
previous unsigned format. Hopefully this will improve compatibility with
crappy clone hardware.
Added a new WARNMODE environment switch to the makefile. Allegro
developers should all set this to get strict warnings, but it will be
left off by default so that the distributed version will be more
forgiving about different compiler/libc versions.
Fixed problem with reading the top and left positions on digital joystick
devices.
Fixed (I think, still waiting accurate confirmation on this one :-)
problem with timers running too fast on some motherboards.
Fixed stupid bug where get_align_matrix() wasn't bothering to zero the
translation vector.
Fixed stupid bug where rotated sprites were coming out upside down in
mode-X and hi/truecolor modes.
Fixed bug where dat utility was truncating long filenames to 8.3 format.
Renamed the ChangeLog file to CHANGES, to avoid problems on 8.3 systems.
Various other minor bugfixes.
============================================================
============ Changes from 3.0 to 3.1 (Jan 1999) ============
============================================================
Changes between the 3.1 beta and final releases: assorted bugfixes,
Antoine Mathys added a Swiss keyboard mapping, Thomas Wolf added a German
translation of the system messages.
Changes between the 3.1 alpha and beta releases: assorted bugfixes, FLIC
routines can now read from datafiles, included rotation optimisations by
Ivan Baldo.
Peter Cech added support for hot-swapping between a custom keyboard
layout and the standard US mapping.
Neil Townsend improved the accuracy of the timer routines.
Added exlights.c example program, showing one way to do colored lighting
effects in a hicolor mode (and also because it makes the total number of
examples a nice round number :-)
Added an afinfo test program, which does the same thing as vesainfo but
for VBE/AF drivers.
Michael Bukin made a lot more portability patches and some bug fixes,
including some improvements to the FLIC player and a much more rational
filename handling system.
Removed the chipset-specific SVGA hardware drivers from the main library
distribution. Instead, these will now be available both as an optional
addon package, and reformatted as part of the FreeBE/AF project.
Added FreeBE/AF extensions support to the Allegro VBE/AF driver (farptr
access to video memory, and the libc and pmode exports needed for future
compatibility with the SciTech Nucleus drivers).
Fixed a bug with the patterned and translucent vline() function in 15 bit
color depths.
Fixed a NULL pointer dereference bug in the config routines.
Fixed an order of processing bug that was causing data to be lost when
calling set_config_file() with the same filename as the current config.
Stepan Roh added a Czech translation of the system messages.
Ole Laursen added a Danish translation of the system messages.
Grzegorz Ludorowski made a new demo game intro animation.
Calin Andrian added 3d polygon timing routines to test.exe.
Peter Cech added grabber support for the 8x8 BIOS font format.
Stepan Roh added a Czech keyboard mapping.
Renamed the Spanish language translation file from SP to ES.
Calin Andrian added a complete set of truecolor polygon rendering
routines, with support for MMX and 3DNow! optimisations and a new masked
lit drawing mode, along with a new polygon clipping function. One minor
change is that POLYTYPE_FLAT mode is now implemented by calling hline(),
so it will respond to the current drawing_mode() settings.
Changed the graphics/sound/joystick driver ID numbers from a zero based
list to a descriptive 4-character string, to make them more readable and
flexible. Added config functions to read/write data in this format. The
sound config data is backwardly compatible, but you will need to manually
update any graphics or joystick driver numbers that are stored in your
config files.
Michael Bukin contributed a _lot_ of patches to improve the portability
and robustness of pretty much the entire library. The only externally
visible change is that the macros used for declaring hardware driver
lists have been redesigned to use a more portable syntax, although the
old syntax is still available as a compatibility macro.
Burton Radons did some more optimisation of the truecolor pixel blending
functions.
Martijn Versteegh added a hook mechanism for extending the config file
system, which can be used to provide extended system status information
or customisation routines for addon packages.
Redesigned the grabber and dat utilities to support source-code "plugin"
modules, which can be used to extend the system with additional object
types, import/export routines, and menu commands.
Ivan Baldo added a dithering option to the 15/16 bit color conversion
routines.
Kerry High added a SNES joypad driver.
Added a font override to the d_text_proc() and d_ctext_proc() GUI
objects, using the dp2 field to specify a custom font.
Michael Tanczos fixed some bugs in the FLIC player.
Cloud Wu optimised the truecolor pixel blending functions.
Paul Pinault added a French translation of the system error messages.
Grzegorz Adam Hankiewicz added a Spanish translation of the system error
messages, and added a new (but undocumented :-) command line option to
the demo game.
Fixed clicks in the interpolated sample mixing.
Fixed a bug with position_mouse() not updating the mouse_pos variable.
Fixed a bug in mode-X horizontal scrolling while the timer retrace
simulator is active.
Added a language.dat file, which can be used to provide translated
versions of system strings (eg. error messages), in a similar way to the
existing keyboard.dat. If you want to use this mechanism from your own
code, replace all your constant strings with calls to
get_config_text("string"). This allows them to be translated by including
a line of the form "string=foreignstring" in the relevant section of
language.dat.
Added an ASCII name field to the keyboard mapping files, in order to make
the setup program a bit more friendly.
Increased the maximum number of sound channels from 32 to 64.
Modified the DIGMID patch loader to support 16 bit samples, rather than
just reducing everything to 8 bit.
Added an interpolation option to the sample mixer (quality=2).
Salvador Eduardo Tropea added support for proper 16 bit sample mixing
(quality=1).
Lee Killough added a lower level hook routine to the keyboard handler.
Removed floating point code from the DIGMID driver, to avoid potential
FPU stack overflows.
Jim Flynn removed floating point calculations from the AWE32 MIDI driver
(these could sometimes cause stack overflows).
Salvador Eduardo Tropea improved the datafile system to avoid linking of
unused code.
Romano Signorelli contributed a Bresenham arc plotting function.
Thomas Wolf corrected some errors in the German keyboard mapping file.
Grzegorz Adam Hankiewicz improved the excolmap example program.
Sven Sandberg optimised the fixed point trig routines.
Fixed some silly crash bugs in the joystick code.
Added a "compress" target to the makefile, based on a suggestion
by Grzegorz Adam Hankiewicz.
Added dummy bitmap acquire/release functions to allegro.h, for
compatibility with the Windows version.
Added a cross-reference facility to the Info format documentation.
Martin Fuller fixed an obscure bug in the reading of compressed .bmp
files.
The emergency exit signal handler now correctly restores the previous
handler, rather than resetting to the default action.
Sven Sandberg optimised the create_light_table() function.
George Foot fixed a bug when the get_mouse_mickeys() routine was called
with both parameters pointing to the same value.
Changed the licensing terms from "swapware" to "giftware". See the
Allegro website for an explanation of the reasons for this change.
Added yet more overloaded operators (this time for long and double types)
to the fix class.
Marius Fodor added support for the Sidewinder and Gravis GamePad Pro.
Many apologies for my taking so long to merge in this code!
Stefan Schimanski optimised the reverse blitting routine (for overlapping
images).
Added a shift+tab reverse focus movement key to the GUI routines.
Grzegorz Adam Hankiewicz added a new example showing how to create and
use a custom color mapping table.
Totally revamped the joystick system (better API and new driver
structure).
Modified the fix class to work properly with gcc 2.8.0.
Added a help.txt "how to get tech support" file.
The midi_pos variable is now negated, rather than cleared to -1, at the
end of a MIDI file. This can be used for measuring the length of a file.
Added a rendering hook to the font structure, for use by text addon
packages.
Improved the VBE/AF text output routine.
Corrected an error in the way the VBE/AF driver interprets hardware
cursor colors.
Pedro Cardoso contributed a tweaked 80x80 VGA mode.
The VBE/AF driver now supports dumb framebuffer drivers as well as
accelerated ones.
Added more accelerator support to the VBE/AF driver (hardware cursors,
lines, vertical lines, triangles, fixed width text output, and
opaque/masked blitting from system memory to the screen).
Added a scare_mouse() function, based on ideas by Martijn Versteegh.
The grabber now stores the "grab from grid" dialog state in allegro.cfg.
Sven Sandberg fixed a problem with save_bitmap() widths being rounded
upwards.
Made the _timer_installed flag globally visible.
Ove Kaaven added linear framebuffer support to the native mach64 driver.
Erik Sandberg optimised the 8 bit draw_sprite() and draw_trans_sprite()
functions.
Michal Mertl fixed a memory leak in the generate_optimized_palette()
function.
Added an ALLEGRO_DATE version define to allegro.h.

variables changing and the pointer being redrawn.
Michal Mertl optimised the clipping code for lines, rectangles, and
circles.
Maiolino Carmelo contributed an Italian keyboard mapping.
Fixed lockup problems caused by the keyboard LED functions on some
platforms/hardware.
Added new create_video_bitmap() and show_video_bitmap() functions.
Added a profile option to the test program.
The keyboard handler now correctly updates the BIOS state for the right
control and alt keys when it shuts down.
Fixed a problem that was preventing the DIGMID driver from reading patch
sets stored in executable appended datafiles.

Fixed some problems with virtual screen sizes in the VBE/AF driver.
Added two new example programs.
The VBE/AF driver now has full support for hardware accelerated drawing.
Added VBE 3.0 support, including new triple buffering routines.
Wrote a routine to select the sound input source (microphone, line input
or CD audio).
Added proper support for stereo samples. This requires an extra parameter
to the play_audio_stream() function, so you will need to change any
programs that use this. I'm very sorry for breaking your old code!
Fixed bugs with the SB16 autodetection and 16 bit sample recording.
Added input support to the raw SB MIDI interface driver.
Wrote a new test program to demonstrate the audio input features.
Ove Kaaven added support for MIDI and audio (sampled sound) input.
The pack_fopen() function now understands nested datafiles as directory
structures, using filenames like "graphics.dat#level1/sprites/zdurgle".
Charles Mac Donald showed me how to set a 160x120 VGA mode, and more
reliable 400x* mode-X resolutions.
Guilherme Silveira and Theuzifan Sumachingun both independently modified
the file selector to only list valid drive letters.

Michael Bevin optimised the create_trans_table() function.
It is now possible to display a mouse pointer without the mouse handler
needing to be installed.

the unary negation operator is now const-correct.
=====================================================================
============ Changes from 3.0 beta to release (Dec 1997) ============
=====================================================================
The pat2dat utility can now import instruments from AWE32 SoundFont files.
Optimised the DIGMID patch loader and fixed a couple of bugs.
Ove Kaaven fixed the ATI mach64 driver.
The config file can now mention several possible video drivers, using
lines in the form gfx_driver=x, gfx_driver2=x, etc.
Improved the native SVGA driver helper functions, making it easier to add
truecolor support to the register level drivers.
Double-clicking on a font object in the grabber now allows you to view
the extended characters as well as normal ASCII.
Markus Oberhumer corrected a potential problem with the Video-7
initialisation code.
Markus Oberhumer, Bitland, and Sormuras all sent me mapping tables for
the German keyboard layout. Coordination of effort: who needs it? :-)
Mathieu Lafon improved the French keyboard mapping.
Fixed some bugs in the MIDI voice allocation system.
Added a -k (keep names) option to the dat utility.
The setup program now uses the ALLEGRO environment variable to locate the
keyboard.dat file.
Fixed a problem with < and > characters in the HTML documentation.
=================================================================
============ Changes from 2.2 to 3.0 beta (Nov 1997) ============
=================================================================
Merged in George's improved instrument parameters for the AWE32 driver.
The pat2dat utility can now reduce sample data from 16 to 8 bits (saves
space, and the DIGMID driver only uses 8 bits in any case).
Added yet another version of the mouse handler, this time in an attempt
to make it work more reliably under Windows NT.
Frodo Baggins added a mapping table for Portuguese keyboards.
Added an external tool "shell" function to the grabber.
Added a "box grab" function to the grabber, which uses a color #255
bounding box to determine the extent of the sprite to grab.
Santeri Saarimaa added a Finnish keyboard mapping.
Finished writing the pat2dat utility, and the DIGMID driver is working a
lot better now.
Mathieu Lafon added support for the Pause and PrtScr keys, and changed
the key[] array to a bitfield indicating whether either or both of the
normal and extended versions of the key are pressed. This remains
compatible with the "if (key[KEY_*])" syntax, but also allows you to
distinguish between, for example, the Enter key on the numeric pad and
the one next to the right shift key.
Fixed a bug in the handling of config variables that don't belong to any
section.
The makefile now tries to detect and warn people about some of the more
common installation errors.
The HTML version of the documentation now uses a short .htm file
extension if it is built on a system with LFN disabled.
Keyboard mapping files now only bother saving the entries that differ
from the default US mapping. This makes the maps a great deal smaller!
Changed the default font and keyboard mapping tables from DOS codepage
437 to the standard ISO charset (first part of Unicode). If you have made
a keyboard config using the old codepage it will need to be updated, but
don't worry, I have a script that can do this very easily.
Fixed a bug in the detection of font formats (fixed or proportional) when
grabbing from a bitmap font.
Added an editable loop point to the MIDI player (thanks to George for
sorting out how to do this...)
Rewrote the mouse handler to track the position itself, using only the
mickey counters from the int 0x33 driver. Hopefully this will fix the
problem with buggy Logitech drivers...
Added a mouse_pos variable containing both the X and Y values in one 32
bit location, to allow a single instruction read during tight polling
loops.
The grabber now supports multiple selection, and has a new "ungrab"
command that copies from a bitmap object into the scratch buffer (you can
use this to generate palettes from truecolor images, or to re-grab a
smaller area from the image).
Added multiple selection abilities to the GUI listbox object.
Theuzifan improved the cpu detection for Cyrix chips.
Mathieu Lafon added a French keyboard mapping.
Richard Mitton wrote an example program demonstrating how to fake a 12
bit truecolor display on an 8 bit card.
Michal Mertl added a routine for generating optimised palettes for a
specific truecolor image.
Optimised the getr/g/b() functions. Converting between different color
depths should be much faster now...
Scott Harrison added code to detect OpenDOS, and use the i_love_bill mode
if their version of EMM386 is in use.
Added some new example programs.
The makedoc utility now converts between the DOS and Windows extended
character sets when producing HTML output files.
Ettore Perazzoli made a spectacular optimisation to the linear ->
mode-X blitting function.
Added a grid option to the dat utility, to specify which region of a
bitmap you want to grab.
Fixed a bug in blitting truecolor bitmaps onto mode-X destinations.
Fixed a bug that was preventing the Adlib volume from being changed when
only MIDI sound drivers were installed.
The grabber can now be run in video modes other than 640x480 (it doesn't
look very nice in lower resolutions, though :-)
Added a new fake scancode for the extended / key (the one on the numeric
keypad) so that the two keys can be distinguished from each other.
Joaquin Hierro Diaz made a mapping table for Spanish keyboards.
The setup utility can now be used to select a keyboard layout and to
calibrate the joystick, as well as for the sound hardware.
Moved some of the documentation to different locations, so hopefully
people will now be less likely to miss the faq.txt, and to bring it
closer in line with the standard GNU distribution format.
Better keyboard configuration system. There is now a proper utility for
setting up the mapping tables, the tables can be read from external
files, and it properly supports the alt-gr and accent escape keys.
Menu items can now be disabled, have check marks next to them, and
support right aligned text eg. for displaying keyboard shortcuts, there
is a new "void *dp" field in the menu structure, and the click callback
routines can now use the global pointer "active_menu" to determine which
option they were called by, if a single routine is shared by several menu
items.
Peter Palotas added an input callback to the keyboard routines, and event
flags to the mouse callback.
Added a -pal option to the dat utility.
Grzegorz Ludorowski made some new graphics for the demo game.
Moved some code to new files and added a bunch of macros so you can
remove unused graphics and sound drivers at link time.
Fabian Nunez added support for the Logitech Wingman Extreme joystick.
Chris La Mantia contributed a d_slider_proc() dialog object.
Sean Gugler added a routine for changing the keyboard LED state.
George Foot added pause and seek functions to the MIDI player.
Added the ability to append datafiles (in fact any files at all) onto the
end of your program executable.
Merged in the AWE32 driver. Long live George!
Can now read RLE compressed TGA files.
Added a mouse movement callback function (useful for detecting double
click events).
Stefan Eilert added support for dual joysticks.
Seymour Shlien contributed a routine for drawing justified text.
Krzysztof Krzyzaniak contributed a loader for .VOC sample files.
Added a rotate_scaled_sprite() function.
Now supports the Dvorak keyboard layout.
Salvador Eduardo Tropea added a 320x100 VGA mode.
Implemented translucent and lit sprite and RLE sprite drawing functions
for the truecolor modes.
Updated the sound setup utility.
The dat utility can now output makefile dependencies for automatically
rebuilding the file when any of the source data changes.
Fixed some problems with the RGB <-> HSV conversion functions.
Truecolor image loading and grabber support.
Phil Frisbie provided some code to detect the CPU type.
Michal Mertl added 24 bit graphics modes. Hurrah!
Added functions for playing streams of digital audio data.
Chris La Mantia contributed a bitmap icon GUI object.
Doug Eleveld added a text box GUI object, plus an improved help system
for the grabber.
Added support for UK and AZERTY keyboard layouts. More can easily be
added if you send me the appropriate scancode -> ASCII mapping tables...
Added get_align_matrix(), qtranslate_matrix(), and qscale_matrix()
functions.
Added a draw_character() function for using sprites as monochrome pixel
masks.
It is now safe to pass the same matrix as both input and output to the
matrix_mul() function.
Paul Bartrum contributed some ellipse drawing functions.
Added some callbacks to the MIDI driver, allowing you to hook your own
code into MIDI notes or marker events.
Added a function to measure mouse movement in terms of mickeys
(difference since the last call) as well as in absolute screen
coordinates.
VolkerOth made the d_edit_proc objects able to scroll, if the string is
larger than the available space.
Added the ability to distinguish between the left and right Control and
Alt keys.
Fabian Nunez added support for the extra keys on a Microsoft keyboard.
Added void *dp2 and void *dp3 fields to the dialog structure. This
ought not to break any existing code, but will let you store a lot more
data when creating custom objects.
The packfile functions can now directly open and read from datafile
member objects, using fake filenames in the form "filename.dat#obj_name".
This means that all the Allegro file access routines (eg. load_pcx() and
set_config_file()) can now read from datafile objects as well as separate
files.
Added miditest and digitest programs to allow more rigorous testing of
the sound routines and patch sets, and a vesainfo program to check which
video modes are available on any given card.
Jan Hubicka wrote a faster version of create_rgb_table().
The grabber now scales the bitmap preview if the image is too large to
fit onto the screen.
Jorrit Rouwe provided a new and much cooler set of FM instrument
definitions for the Adlib MIDI driver.
Added a function to load .IBK patch sets for use by the Adlib driver.
Added a wrapper allegro/ directory around the contents of the zip file,
so it can now be safely unzipped into the main djgpp directory.
Richard Mitton added support for 6-button joysticks.
Truecolor (15, 16, and 32 bit) graphics modes.
Vastly improved sound routines (more flexible API, now supports up to 32
simultaneous voices on the SB, sample-based MIDI playback driver, can
reverse samples, volume/pan/pitch sweep effects, MIDI commands can be
output on the fly as well as played from MIDI files, and lots of other
goodies).
It is now possible to update the status of GUI dialogs incrementally from
your own control loops, with an update_dialog() function, rather than
completely transferring control to do_dialog().
Compressed files (including grabber datafiles) can now be encypted with a
password.
Added a masked_blit() function, that skips zero pixels.
Added code to detect being run under Linux DOSEMU, and use the less
demanding version of the timer code if this is the case.
Added a standardised configuration mechanism. The format for saved
joystick calibration information has changed, so existing joystick files
are no longer valid.
Added a textprintf() routine, which uses a printf() style format string.
Added a TexInfo version of the documentation (thanks for the help,
Francois!)
Jonas Petersen added a save_bmp() function, and support for the OS/2 BMP
format.
=============================================================
============ Changes from 2.11 to 2.2 (Feb 1997) ============
=============================================================
TBD/FeR added tweaked 320x600 and 360x600 resolutions to the mode-X
driver.
Matthew Bowie added support for 4-button joysticks.
Dave Thomson added RGB <-> HSV conversion functions.
Added a 'freeze_mouse_flag' variable, that can be used to lock the
pointer to a specific position.
Added a 'key_led_flag' variable, that can be used to prevent the keyboard
LED's updating in response to the capslock, numlock, and scroll-lock keys.
The midi player now resets midi_pos to -1 when the music finishes playing.
Adrian Oboroc wrote an LBM loader.
Fonts can now contain characters above ASCII 127.
Chris Wigman made a better intro animation for the demo game.
Added translucency, color blending, and lighting routines (based on code
by Owen Embury and ideas by Nathan Albury).
Added 3d math and matrix manipulation functions.
Added texture mapped and gouraud shaded polygon drawers.
Tim Gunn contributed code for reading and writing TGA files.
Fixed clamping problems with rotating non-circular sprites.
Added scrollbars to the GUI listbox object.
Seymour Shlien wrote a bezier spline drawing function.
Added fixed point fadd() and fsub() functions, which check for overflow.
Added pack_fseek() and chunk manipulation functions to the file routines.
Improved datafile structure and grabber program.
Wrote a utility to convert grabber datafiles into linkable asm code.
Salvador Eduardo Tropea improved the keyboard routines (better handling
of extended scancodes, keyboard LED support, capslock and numlock, and
alt+numpad input).
Fixed the packfile functions and file selector to work with long
filenames under win95.
Seymour Shlien contributed a BMP reader.
Added a hook function to the keyboard code, allowing you to use the GUI
code without installing the keyboard handler.
Fixed a lockup caused by trying to access non-existent floppy drives.
Francois Charton wrote a driver for Paradise graphics cards.
Chris La Mantia contributed a radio button GUI dialog object and added a
D_DISABLED object flag.
Markus F.X.J. Oberhumer fixed the Video-7 scrolling function.
Converted the docs into HTML format.
Added code to detect Windows NT.
Mark Habersack added support for newer Trident chipsets.
Did some more work on the VBE/AF driver (it now works, but still doesn't
support accelerated hardware features).
Fixed bugs in the WAV sample reader and FLIC player.
Added special 'windows friendly' mode to the timer code. You can now even
run demo.exe under Windows 3.1!
Reorganised directory structure, to allow for a Linux version. The output
liballeg.a is now found in lib/djgpp.
Added support for 8x16 BIOS format fonts.
Fixed a problem with overflow when rotating large sprites.
Fixed a problem with restoring the text mode screen height after running
Allegro programs.
=============================================================
============ Changes from 2.1 to 2.11 (Nov 1996) ============
=============================================================
Fixed bug in bank.S.
install_mouse() now sets the range to (0,0,SCREEN_W,SCREEN_H).
install_sound() does not automatically set the volume to maximum.
Added ++ and -- operators to class fix.
Makefile now copies liballeg.a to lib, and allegro.h to include.
Made a few changes to work under LFN=y (if you use unzip or winzip
instead of pkunzip).
Added manifest.
Clarified installation instructions.
=============================================================
============ Changes from 2.0 to 2.1 (June 1996) ============
=============================================================
Mode-X support (thanks to Jonathan Tarbox and Dominique Biesmans for
suggesting and then helping to implement this).
Compiled sprites.
Jonathan Tarbox contributed an FLI/FLC player.
Added patterned drawing modes.
Added a vertical retrace interrupt simulator.
polygon() can now handle concave and self-intersecting shapes. I also
changed the parameters a bit. Sorry if this breaks your old code, but
it's more efficient the new way...
Added stretch_sprite().
Wrote a floodfill() routine.
More flexible palette fade routines.
Added set_volume() to the sound code.
David Calvin wrote a sound setup utility.
Improved the GUI. Added popup/dropdown menus, joystick input, three
button alert boxes, better handling of arrow key focus movement, a new
keyboard shortcut object (d_keyboard_proc()), and '&' markers in strings
to display keyboard shortcuts. The GUI can also now be used with fonts
other than the standard 8x8 default, by altering the global 'font'
pointer.
Fabian Nunez added support for the CH Flightstick Pro joystick (looks
cool: I want one :-) and 3-button mice.
The keyboard handler now responds to the state of the ctrl and alt keys,
and there is a new simulate_keypress() function.
Mark Wodrich added sub-bitmaps, which share their memory with a parent
bitmap but can be positioned anywhere within it, and have their own
clipping rectangles.
Mark also modified the mouse driver to double-buffer the pointer (so it
doesn't flicker any more), and added a set_mouse_sprite_focus() function.
Added set_mouse_range() and set_mouse_speed() functions.
Thanks (again) to Mark Wodrich, the grabber can now import GRX .FNT files.
The grabber can now make backups when saving datafiles, and it only
writes the datafile headers if their contents have changed, to prevent
unnecessary recompilation.
Added a text_height() function.
The fixed point inverse sin and inverse cos functions now use lookup
tables, which makes them a lot faster.
Reorganised the directory structure, added some example programs, and
improved the documentation.
=======================================================================
============ Changes from 2.0 beta to release (March 1996) ============
=======================================================================
Marcel de Kogel fixed some problems with the MPU-401 driver. It now
actually works :-)
Marcel also provided some better drum sounds for the Adlib driver.
Inlined the fmul() and fdiv() functions.
Much faster fsqrt(), taken from Arne Steinarson's fix-float library.
Added inline bmp_write_line(), bmp_read_line(), and _putpixel() functions.
The keyboard routines now support the emergency abort sequence
ctrl+alt+del, and there are signal handlers to make sure Allegro will
shut down cleanly if your program crashes.
Wrote new irq wrappers that can deal with reentrant interrupts.
Added joystick routines (based on code provided by Jonathan Tarbox and
Marcel de Kogel).
Moved some functions to different files and juggled things about so the
linker can do a better job. If you don't use the sound stuff, or don't
use any graphics functions, now they won't be linked into your executable.
Marcel de Kogel manged to locate my (embarrassingly stupid :-) mistake
which was preventing the VESA 2.0 linear framebuffer driver from working.
Various other performance enhancements and bug fixes.
=====================================================================
============ Changes from 1.x to 2.0 beta (Jan/Feb 1996) ============
=====================================================================
Dropped all the Borland code. A couple of months ago I ran out of disk
space, and it was with great satisfaction the I executed the command
'deltree /y c:\bc4'. It was a horrible compiler, and I'm glad it's dead.
Added SVGA support. As a result it no longer makes sense for
allegro_init() to put the system into mode 13h, so you will be in text
mode until you call set_gfx_mode().
Added sound code (background MIDI music and sample mixing).
Added support for proportional fonts (of any size) as well as the old 8x8
fixed size ones.
XOR drawing mode.
There is no longer such a thing as a SPRITE structure. The sprite drawing
code now draws bitmaps onto other bitmaps, which is a much more flexible
way of doing things. The datafile reader will convert all your old
sprites to bitmaps as it loads them in, so the only practical difference
this is likely to make is that the sprite drawing routines can't draw
opaque sprites any more (but you can use a blit instead).
show() and get_sprite() no longer exist: use blit() instead.
Added flipped and rotated sprite draw routines.
Added bitmap scaling.
Added RLE sprites.
drawsprite() has been renamed to draw_sprite().
textmode() has been renamed to text_mode(), to avoid conflicts with
definitions in conio.h.
All the file access functions have been renamed from the stdio syntax to
pack_fopen(), pack_getc(), etc, so they can now be mixed with stdio code.
Added pack_fgets() and pack_fputs().
The port_callback pointer no longer exists.
Removed polyline() (who ever used it?), and added a polygon(), which
draws a filled convex polygon with an arbitrary number of vertices.
Added do_line() and do_circle() functions, which call a user-supplied
function for each pixel that needs to be drawn.
Added a default keyboard interface to the GUI routines, allowing the
selection of objects with the arrow keys and <enter>.
Added several new GUI messages and flags. In particular there are now
messages for tracking mouse cursor movement, an idle message, a special
return value for the MSG_CHAR message which allows an object to override
the default keyboard handling, and a flag which hides the object.
There are new GUI routines to centre a dialog on the screen and to alter
the colors used by the standard alert and file selector dialogs.
The file selector now takes a third parameter specifying which file
extensions to display.
The timer routines now have better than millisecond accuracy, and it is
possible to alter the speed of a user timer callback in realtime (by
reinstalling it with a different speed value).
Removed the _RGB struct and paltorgb() functions. RGB's are now stored
directly in the hardware format, with each value in the range 0-63.
Added functions to get and set single palette entries as well as entire
palettes.
Added DPMI memory locking code.
Wrote a C++ 'fix' class which overloads a lot of operators, providing an
easy way to use the fixed point routines.
There are probably lots of other things that I have forgotten about.
