The Ignite Realtime community is very proud to release Openfire 3.10.0 for general availability from http://www.igniterealtime.org/downloads/
The amount of energy that has gone into this release is truly impressive, and it shows no signs of slowing down - as those of your looking at the 3.11 branch will have seen. Further 3.10.X releases will be bugfix releases; 3.11 will concentrate on a path to 4.0.0.
3.10.0 itself brings new core features to Openfire (such as Message Carbons, for example, by Christian Schudt) and vital improvements (to clustering and MUC, for example, by Tom Evans), as well as some hard bugfixing (by Guus der Kinderen) and important security improvements.
As ever, we welcome pull requests (to 3.10 or master as appropriate), and the entire development team is looking forward to you joining the conversation either in the forums or in the XMPP chatroom at firstname.lastname@example.org
UPDATE: Spark 2.6.3 version has issues with connecting to this version of Openfire. We suggest updating to just released 2.7.0 version of Spark.
UPDATE 2: Openfire 3.10.1 has been released recently, which is again compatible with Spark 2.6.3 when using TLS (thanks to this fix [OF-907] SSLv2 Hello is rejected; prevents some clients connecting - Jive Software Open Source )
