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.
