NEWS - list of user-visible changes between releases of LibGGI

New in 2.1.0: 2004-11-30:
- Documentation updates
- removed obseleted Xlib target
- added new GGIFLAG_TIDYBUF flag. It is intended for applications
  using directbuffer and having their own dirty-region
  management. Currently only supported by the X-target.
- KGI target improvements
    - added Matrox Gx00 accelerator sublib
    - added devfs support
    - added multiple frame support
    - merged improvements from the FreeBSD ports tree
- fbdev gammamap support
- added the -fullscreen option to the X-target
- added the -physz option to the ipc-target
- Major DirectX target improvements
        - added -noinput and -physz options by Christoph Egger. Tested by Albert Graef.
        - fix cursor stuff, added -keepcursor and -nocursor options (patch from Albert Graef)
        - disable maximize button on GGI-on-DX window (patch from Albert Graef)
        - remove stuff in WindowProc made obselete by the above two items (patch from Albert Graef)
        - move the globals in ddinit.c into private data structure (patch from Albert Graef)
        - merge the two targets into one (directxnt has been renamed to directx and is now the *one* directx target)
          (patch from Albert Graf)
        - fix a couple of bugs and race conditions (patch from Albert Graef)
        - added -inwin option (patch from Albert Graef)
        - added support for virtual size != visible size.
        - added support for panning (ggiSetOrigin)
        - added support for up to 16 frames.
        - added support for asynchronous mode (no background updates when active).
        - added support for fullscreen and mode switching.
        - preliminary support for palettized modes.
- display-auto has been added. It replaces the 5 years old linux specific target autodetection and handles it OS dependend
- works on Windows using MinGW w/o requiring special Makefiles.
- a pseudo-stubs target has been added by Peter Ekberg. It does effectively nothing, but gives extensions
  a way to have one target that stands for all targets that passes all operations to their parent visuals.
  libggiwmh and libggimisc make palemu and trueemu working with it w/o having a target for each of them.
- display-mansync has been reworked by Peter Ekberg. It now uses the platform independent task scheduler.
- added a new macro: GT_ByPPP which is basically GT_ByPP but for packed pixels and it takes two arguments.

^L

New in 2.0.6: 2004-09-14:
* build system:
  - Prepend with GII include path when --with-uninst-gii is specified via configure
  - disable vgagl helper when not building the svga target
* X-target:
  - Bugfix: Ensure aligned memory access. Fixes crash on NetBSD/sparc64
  - Bugfix: Perform correct clipping in ggiFillscreen(3).
* display-memory: Bugfix: Free directbuffer completely.
* display-monotext: Bugfix: ggiCheckMode() returns actual error code than always success.

^L

New in 2.0.5: 2004-05-29:
* X-target:
  - Fix over-allocation of win y dimension.
  - Forward expose events to the application when -nobuffer is used.
  - Fix "strange colored pixels when re-exposing backbuffer"-Bug.
  - Focus pulling fix. Key focus should no longer get lost,
    when the mouse is NOT over the window. Note: Don't forget to
    update libgii's input-xwin and input-x before as libggi now
    passes some additional information to libgii.

* X-target:
  - minor mode initialization fix from Argo Vessmann
  - shm helper checks return code, when setting up the directbuffer
  - release locking on failure. (Threadsafety fix)
  - fixed geometry check. Opening (very) small windows is now possible.

  disables all targets requiring them, if not present.
* cbconsist demo: sync with devel tree
* gcc 3.3 compiling fix for default/linear_16/crossbuild.c
  (fixes Debian bug #197214)

  compile on FreeBSD (fixes FreeBSD PR ports/52380)
^L

    the same sort of X visuals
* Demo: Improved pageflip demo to test all primitives in a
  multi-frame environment

New in 2.0beta2: 1999-04-01;
* Portability fixes for non-Linux platforms.
* Lots of bugfixes.
* Documentaion updates.
* Optimizations of the linear-* drawing libraries - now software drawing,
  ggiCrossBlit() and ggiPutBox() is much faster.
* Linux VT-switching now works with pthreads.
* New environment variable GGI_NEWVT which will cause Linux-console based
  targets to open a new VT instead of running on the current one.
* API for requesting Linux-console based targets not to halt when switching
  to another VT.
* New API functions ggiSetColorfulPalette(), ggiFlushRegion(),
  ggiResourceAcquire(), ggiResourceRelease(), ggiResourceMustAcquire(),
  ggiResourceFastAcquire(), ggiResourceFastRelease(), ggiEventsQueued(),
  ggiEventSend() and ggiEventSelect().
* ggiGetSelectFdSet() removed.
* The config file is now stored in /usr/local/etc/ggi by default.
* Support for setting the mansync framerate.
* New configure option --with-uninst-gii, which makes it possible to
  build LibGGI against an uninstalled copy of LibGII.
* All targets should now be compatible with Linux devfs systems.
* Support for targets using asynchronous acceleration.
* Big improvements in the event handling code, see the LibGII docs and NEWS
  file for info.

* stars-demo
  - Demonstrate how to runtime switch between X and DGA targets with help

  - Don't close and reopen the window when changing modes.
* DGA-target
  - Use our own client-side implementation of XFree86DGA to get better
    stability and support for optionally mapping the video memory from
    a framebuffer device (= no root privs required for DGA).
  - Support for acceleration on X servers supporting DGA 1.1.
