<P>
Note that this is a <STRONG>major new distribution</STRONG> and lots
of things have changed. Consult the <A HREF="hylafax4.0.html">general overview</A>
for a high-level description of the new functionality provided in the
v4.0 software.
<P>
This document describes the changes made to the software between the
<I>previous</I> and <I>current</I> versions (see above).
If you don't find something listed here, then it was not done in this
timeframe, or it was not considered important enough to be mentioned.

<A NAME="general"><B><FONT SIZE=+3>G</FONT>ENERAL CHANGES:</B></A>
<UL>
<LI>server machines must now be setup for use with the
<B>faxsetup</B> command
<LI>each inbound or outbound call
handled by HylaFAX is now given a unique number termed a
<I>communication identifier</I>; session logs are now written
to separate files in the <B>log</B> directory whose names are
based on the assigned communication identifier
<LI>the format of the accounting file <B>etc/xferfaxlog</B> has
changed to include the communication identifier and the client-specified
job tag identifier (for outbound calls); the latter is useful for
sites that use job tags for accounting purposes
</UL>
<P><HR WIDTH=65% ALIGN=right>
<A NAME="configure"><B><FONT SIZE=+3>C</FONT>HANGES IN THE SOFTWARE CONFIGURATION:</B></A>
<UL>
<LI><B>configure</B> now emits the correct definition for
<TT>CONFIG_BADEXECVEPROTO</TT> for AIX systems
<LI>the check for support for memory-mapped files was corrected
<LI>various configuration parameters now need an explicit ``auto''
setting to get <B>configure</B> to select a value based on the
build environment
<LI>fewer files are dependent on the build environment because of the
addition of the <B>faxsetup</B> command and the work it does to
configure the software according to the target system
</UL>
<P><HR WIDTH=65% ALIGN=right>
<A NAME="faxq"><B><FONT SIZE=+3>C</FONT>HANGES TO FAXQ:</B></A>
<UL>
<LI>a new flag bit was added for tracing error messages from the TIFF library
<LI>the calling sequence for the <B>notify</B> script was changed
<LI>a new <TT>-m</TT> option is now passed to all document converters
to indicate the maximum number of pages that should be permitted
in a converted document
<LI><B>faxq</B> now returns (more) informative error messages
when it recognizes that a document conversion failed but the
converter program did not exit with an error
<LI><B>faxq</B> no longer assumes that document conversions overwrite
the output file it creates
</UL>
<P><HR WIDTH=65% ALIGN=right>
<A NAME="faxsend"><B><FONT SIZE=+3>C</FONT>HANGES TO FAXSEND:</B></A>
<UL>
<LI>the calling sequence for the <B>pollrcvd</B> script was changed
</UL>
<P><HR WIDTH=65% ALIGN=right>
<A NAME="faxgetty"><B><FONT SIZE=+3>C</FONT>HANGES TO FAXGETTY:</B></A>
<UL>
<LI>a bug was fixed in the Caller-ID support that caused information
to be discarded in certain cases
<LI>the calling sequence for the <B>faxrcvd</B> script was changed
<LI>a bug was fixed in the Group 3 decoder's recognition of EOL codes
that follow an error in the input stream
</UL>
<P><HR WIDTH=65% ALIGN=right>
<A NAME="hfaxd"><B><FONT SIZE=+3>C</FONT>HANGES TO HFAXD:</B></A>
<UL>
<LI>the parsing of time values was made more robust
<LI>the handling of absolute time values (e.g. <TT>SENDTIME</TT>) was corrected
<LI><TT>RETRYTIME</TT> values are now interpreted as minutes and seconds
rather than hours and minutes
<LI><TT>SENDTIME</TT> values are now always interpreted relative to GMT
<LI><B>hfaxd</B> is now installed setuid root so that it functions
correctly when started from <B>inetd</B>
<LI>the SNPP support now sets the job <TT>RETRYTIME</TT> based on the
service level; this corrects a problem where a job could time out
before multiple attempts were made to complete the transmission
<LI>a <TT>RetryTimeMap</TT> configuration parameter was added to control
the SNPP service level-to-<TT>RETRYTIME</TT> mapping
</UL>
<P><HR WIDTH=65% ALIGN=right>
<A NAME="faxaddmodem"><B><FONT SIZE=+3>C</FONT>HANGES TO FAXADDMODEM:</B></A>
<UL>
<LI><B>faxsetup</B> must be run before configuring modems; <B>faxaddmodem</B>
no longer does any of the basic system verification and setup work
that it used to (e.g. creating a ``fax'' user)
<LI>system-specific support for communicating with modems is now taken
from the file <B>etc/setup.modem</B> created by <B>faxsetup</B>
</UL>
<P><HR WIDTH=65% ALIGN=right>
<A NAME="faxmail"><B><FONT SIZE=+3>C</FONT>HANGES TO FAXMAIL:</B></A>
<UL>
<LI>configuration files are now read
<LI>the meta-header handling has been improved; it is now simpler to
specify the set of headers to keep from the envelope
<LI>headers are now matched in a case-insensitive manner
<LI>meta-headers were added to control the fonts used to format the envelope
</UL>
<P><HR WIDTH=65% ALIGN=right>

<LI>a bug was fixed in memory-mapped file handling used for facsimile
job submissions
<LI>a bug was fixed in the SNPP client code for transmitting
a <TT>HOLD</TT> time
<LI>a bug was fixed in the fax client code for transmitting
a <TT>SENDTIME</TT> value
<LI>the System V script for starting the HylaFAX servers at boot time
is now dependent on the work of <B>faxsetup</B>
<LI><B>probemodem</B> is now dependent on the work of <B>faxsetup</B>
<LI><B>faxcron</B> is now dependent on the work of <B>faxsetup</B>
<LI><B>faxcron</B> was updated to understand the new session log scheme
<LI><B>faxmodem</B> now accepts full device pathnames for consistency
with other similar programs
