Change log for HawkVoice

Version 0.5 alpha (unreleased)
Added the chat API for simple point to point communications


Version 0.4 alpha (non-working source code release)
Added codectest.c to test the codecs
Fixed LPC codec
Fixed LPC-10 codec
Fixed 'pop' in ADPCM codec
Profiled the codecs, and just changing C code made the following speed improvements:
  LPC-10, encoding >65%, decoding >20%
  LPC   , encoding none, decoding >55%
  GSM   , encoding none, decoding >15%


Version 0.3 alpha (non-working source code release)
Moved group API over to HawkNL
The HawkVoice network protocol should now be complete
Major rewrite of the LPC code to allow multiple encoding and decoding streams
Changed the interfaces to the ADPCM, LPC-10, LPC, and GSM codecs for more consistency


Version 0.2 alpha, never released
Ported over the following code from SpeakFreely: ADPCM, GSM, LPC, LPC-10, MD5, and Blowfish
Added my own u-law codec
De-linted all the SpeakFreely source code
Found a newer version of the GSM code, so now the de-linting begins again...
OpenH323 has a newer (and better) version of LPC-10, so I am now using that version


Version 0.1 alpha
Initial version, split off from HawkNLU, never released
