  samples

  bar)

- added "Whats this" help text to the GUI controls in the general settings
  dialog, added Tool Tips to some GUI controls

- server logging history grid lines of weekend days are now plotted with
  different line width

- removed ALSA support since the ALSA interface implementation in llcon was
  buggy and will not be maintained in the future

- new server features: for chat messages the time stamp is also shown, parsing
  of existing log file supported

- updates for help texts

- new design for fader tag

- change for Jack Linux audio interface: ports are only registered and
  connected once when the software is started up

- bug fix: under bad network conditions chat messages were randomly repeated

- bug fix: in case the server was shutdown and restarted during a connection,
  the channel name was not updated correctly at the server


3.0.1 (2009-08-23)

- use low complexity CELT encoder profile, this lowers audio dropout
  probability on slow computers

  of network trouble)


3.0.0 (2009-08-19)

- introduced new audio codec "CELT", not compatible to old versions

- only the sound card frame sizes 128, 256 and 512 are allowed (since other
  frame sizes require additional conversion buffers which introduce delay)

- IMA-ADPCM, MS-ADPCM removed

  intermediate audio buffers, client audio buffer size equals network
  buffer size now)

- added upload rate limitation for server (server decides which network
  parameters to use depending on the upload limit and the number of connected
  clients)


2.1.4 (2009-02-15)

- added automatic jitter buffer size setting

- speed optimizations to improve audio interface stability

- new default settings (e.g. turn off Reverb by default since it requires
  significant CPU)

- added sound card selection

- improved ASIO configuration

- added total delay display


2.1.2 (2008-08-15)

  server according to the setting in the client (they are coupled now)

- removed sample rate offset estimation since it was not used anyway

- internal audio processing in the server is now based on the minimum block
  size (improves latency)


0.9.1 (2006-01-28)
