1.2.4

Mumble 1.2.4, the successor of 1.2.3 has been released on June 1st 2013. For a list of known issues, please visit the 1.2.4 known issues page.

Mumble (Client)
List of new features, improvements and bug fixes already in place for the upcoming release.

Next generation audio codec
"The Opus codec is designed to handle a wide range of interactive audio applications, including Voice over IP, videoconferencing, in-game chat, and even remote live music performances. It can scale from low bit-rate narrowband speech to very high quality stereo music." - http://www.opus-codec.org/

This new codec will allow Mumble to perform better at even lower bitrates then previously possible. It incorporates technology from Skype's SILK codec and Xiph.Org's CELT codec, previously the main codec for Mumble. This codec is a IETF internet standard and has already been adopted in Firefox. 

Windows 8 support
With 1.2.4 Mumble is now officially supporting Windows 8.

We recommend all users on Windows 8 to upgrade: 1.2.3 has many known issues with the platform including known issues with the UI and Overlay. 

Push-To-Talk improvements

 * For touch/stylus centric interfaces Mumble now offers a Push-To-Talk button window. If enabled the window is always on top so you can keep using other applications. The PTT-Window can be enabled via Configure → Settings → Audio Input (Push-To-Talk needs to be selected) → Display Push-to-Talk Window.


 * You now also have to option to configure a Hold-Time for Push-to-Talk of up to 5 seconds. After releasing the Push-to-Talk key Mumble continues to send voice for the configured time. If you sometimes release your PTT key to early this might come in handy for you.


 * Last but not least audio cues are now available for Push-To-Talk, Voice Activity and Continuous modes.



Volume attenuation improvements



 * Volume attenuation is now available for PulseAudio (Linux)
 * Mumble now opts out of volume ducking on Windows >= 7



Other audio features

Chatlog

 * “Intelligent” chatlog scrolling If you get new messages in the chatlog while you are not scrolled to the bottom, Mumble will no longer scroll down automatically to the last entry in the chatlog. This is helpful for scrolling and reading the chatlog while activity is still going on.
