The upcoming Client Release 3.0.13 is now available for testing in the beta channel.

This client enables the channel delete delay (requires server 3.0.10), removes the DirectX Input system and fixes a few bugs.

The full changelog can be found below:
=== Client Release 3.0.13 30 Sep 2013
+ Added support for channel delay feature in server 3.0.10. This allows to set
  a delay in seconds after which temporary channels will be deleted after the
  last client has left. To configure a virtualserver default, set the delay in
  the virtualserver edit dialog. Or configure per channel in the channel edit
  dialog. Channel templates were adjusted to show the delete delay and a count-
  down until the channel is removed.
+ Added search field in customize toolbar dialog.
+ Added display of filetransfer progress in taskbar (Windows 7 and above).
* Removed deprecated Direct Input hotkey system, meanwhile replaced by the
  "Default" hotkey system.
- Fixed assigning hotkey when key was mapped or deactivated via "ScanCode Map".
- Fixed avatar animation when an animated gif will be set after a jpg.
- Fix for Overwolf integration, avoid getting back to desktop when TeamSpeak
  is started by Overwolf in-game and immediately a dialog opens.
