The Ignite Realtime community has just released Spark 2.7.6 and it can be downloaded from Ignite Realtime: Downloads.
In this release more patches went into fixing Mac OS X version (issues with Preferences, File transfer, etc.). Thanks to speedy for working on this. Also as part of fixing issues on Mac we have applied an experimental version of Libjitsi patch by cstux (Voice Chat module). We haven't been able to test, if it works better (or at all). So waiting for a feedback on this in Updated Voice Chat module testing. Thanks to Alexander198961 · GitHub for his patches fixing broadcast and other issues. Waiting for more from him.
For a complete list of changes please check Spark Changelog
Here are sha1 checksums for the downloads:
[Voice Chat] Voice chat module has received an experimental patch and still needs testing and probably not working correctly.
[Mac OS X] Installer is now bundled with Java JRE, so it is easier to start using it and many issues has been fixed.
[Linux] Linux version has issues with menu not showing up and chat window not opening normally on the latest Ubuntu version. Also flashing plugin is not working on Linux systems.
