Download Mumble 1.2.9

Mumble is an open source and cross platform VoIP program. Clients are available for Windows, OS X, Linux, and iOS. Communication always takes place over an encrypted connection and has a low latency. If it is used within games, an overlay can be used to show who is speaking and, in addition, the program is able to recognize the position of the other person and reproduce the sound in such a way that you can hear where that player is located. . Version 1.29 of Mumble was released on Saturday and this release comes with the following release notes:

mumble 1.2.9

The Mumble team has released version 1.2.9 of the Mumble VoIP application. Version 1.2.9 is a maintenance release in the stable 1.2-series of Mumble.

This release contains a couple of bug fixes to the Mumble client and contains updates to various Mumble dependencies, most prominently OpenSSL (1.0.1n) and Qt 4.8 (latest from Git). It is also the first release in the 1.2.x series that enables TLS 1.2 and modern TLS cipher suites.

If you are using one our packaged static Murmur servers, or Murmur on Windows, or any of our packaged Mumble client packages we advise you to update to get the latest security fixes from our dependencies.

Changes in this release:

• OpenSSL has been updated to 1.0.1n.
• Qt 4.8 has been synced to the latest sources from Git.
• Mumble and Murmur now use TLS 1.2 if the server/client combination allows it.
• Mumble and Murmur now prefer ECDHE + AES-GCM cipher suites if possible, providing Perfect Forward Secrecy.
• For a source-level changelog, please see
• All of these changes are already available in our snapshot builds (the 1.3.x series), so if you like living on the bleeding edge and want to help out with Mumble development, feel free to check out our development snapshots at
• The TLS 1.2 support in our binary packages is backported from Qt 5. Unfortunately, that means that if you are using Mumble from a package manager, you’re not going to get a TLS 1.2-enabled build.
