We just released a new bigger TS3 client update.
A lot has changed and a lot has been fixed and added into this version.
- You can now connect to the free servers (generated in TS5 client)
- Automatic voice volume leveling (AGC) is no longer a recording setting. We moved that feature into Playback.
Clients with older version may not hear you as loud as before. Please tell them to update their client. - This versions adds a new settings for capture when using VAD.
When updating old capture profiles the client will select Volume Gate.
Automatic is selected for users without old config or when a new profile was created. - Multi track recording has been improved and a crash got fixed here
- The Plugin API ws raised to 24 but client still will be able to use plugins that are build on version 23
- A whisper bug where whispering user moved into unsubscribed channel (it’s not in the change log sorry)

artificial silence while being connected to a TeamSpeak Server.

auto-connecting on startup (example: -connect=voice.teamspeak.com). Some
additional parameters can be used to provide more details (-pw, -nickname,
-channel, -channelid, -channelpw, -newtab, -mytsid, -showqueryclients,
-capture, -playback, -hotkeys).
+ Added support for upcoming TeamSpeak Server releases using a PostgreSQL
database backend.

related tools.

* Qt color roles can now be customized in themes (e.g. for hyperlinks).
