What's new in Julius-3.5.2 ?
=============================

Julius/Julian rev.3.5.2 is a minor update to improves performance on
Windows, enhancements and fixes for word graph outputs, and other bug
fixes. All users of previous version is encouraged to upgrade to 3.5.2.

Summary of changes in 3.5.2:

o Speed-up and improvement on Windows console.
- DirectSound
- Recent MinGW support
o More accurate word graph output.
- new optimization params: -graphcut, -graphboundloop, -graphsearchdelay
o Add capability to output word graph instead of trellis on 1st pass.
o Bug fixes.
o Imprementation improvements.

Details of the changes are listed in "Release.txt".

Please note that if you want to compile Julius with DirectSound
support, you need DirectX headers installed in your mingw / cygwin
environment. If not exist, configure will choose an old interface.
Please see install instruction on the Web.

3.5.2 (2006.07.31)
===================
o Speed-up and improvement on Windows console:
- Support DirectSound for better input handling
- Support input threading utilizing callback API on portaudio.
- Support newest MinGW (tested on 5.0.2)

o More accurate word graph output:
- Add option to cut the resulting graph by its depth
(option -graphcut, and enabled by default!)
- Set limit for post-processing loop to avoid infinite loop
(option -graphboundloop, and set by default)
- Refine graph generation algorithm concerning dynamic word merging
and search termination on the second pass.

o Add capability to output word graph instead of trellis on 1st pass:
- 1st pass generates word graph instead of word trellis as
intermediate result by specifying "--enable-word-graph".
In that case, the 2nd pass will be restricted on the graph, not
on the whole trellis.
- With "--enable-word-graph" and "--enable-wpair" option, the
first pass of Julius can perform 1-pass graph generation based
on 2-gram with basically the same algorithm as other popular
word graph based decoders.

o Bug fixes:
- configure script did not work on Solaris 8/9
- "-gprune none" did not work on tied-mixture AM
- Incorrect error message for AM with duration header other than "NULLD"
- Always warns abount zero frame stripping upon MFCC

o Imprementation improvements:
- bmalloc2-based AM memory management
