Babbler Version 0.7.4 released

Version 0.7.4 of the Java XMPP library has been released to Maven Central!

It turned out there was a rare deadlock, when using Stream Management. It happened only rarely and was hard to spot, but when it did, it was of course a blocker.

Here's the full changelog:

• Resolve rare deadlock when using Stream Management
• Rework how WebSocket connections are closed
• Don’t let a stream error close the stream immediately, but instead wait for the closing stream element and then close the connection.
• Increase performance of IBB stream
• Prevent rare, but possible NullPointerException after sending stanzas.
• Fix error when using pages (XEP-0141) within data forms (XEP-0004)
• Reset nick to null, if entering a chat room fails
