The Ignite Realtime community has just released Spark 2.7.4 and it can be downloaded from Ignite Realtime: Downloads.
This update is a lot about updating translations (Russian, Chinese (Traditional), Lithuanian, etc.) and making some hardcoded parts of GUI available for translation. Also an old patch for proxy connection has been applied in this version, but it looks like Spark is ignoring proxy settings and connects directly instead. Needs more live testing (please report in the forums).
For a complete list of changes please check the official Spark Changelog
We are glad to receive patches from contributors on igniterealtime/Spark · GitHub. 6 of them included in this release. Thank you, guusdk (Guus der Kinderen) · GitHub, idma88 (Dmitrii Ivanov) · GitHub and CrystalLee. We hope more developers will find out about this and other Ignite Realtime projects and contribute patches.
Here are sha1 checksums for the downloads:
[Voice Chat] Voice chat is broken since the migration from proprietary JMF to free FMJ framework and there is no fix in the works. Spark project lacks good java developers.
[Mac OS X] There is no installer for Mac OS X (installer building system has issues with Mac OS X, also Spark has too many major issues on this platform).
[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.
