o Remove compatibility code. Use the atom 'undefined' in JIDs (normal
and short). o Add try/catch blocks where Exmpp can raise exceptions. o Remove some unused code. o Convert on-disk Mnesia database: JIDs, extra XML elements and askmessage are concerned. o By default, 'askmessage' is now an empty binary instead of an empty string, for consistency's sake. o Fix some bugs.
