Less likely to send messages to a contact's idle/inactive resource.

Now, messages are sent to the bare JID upon receipt of any presence change from the contact.
Added support for the SCRAM-SHA-1 SASL mechanism. This is only available when built without Cyrus SASL support.
When getting info on a domain-only (server) JID, show uptime (when given by the result of the "last query") and don't show status as offline.

The default value for the file transfer proxies is automatically updated when an account connects, if it is still the old (broken) default (from 'proxy.jabber.org' to 'proxy.eu.jabber.org').

Double-clicking usernames in chat history will open an IM with that user.
Put an icon on the "Filter" button in the debug window.
Don't treat "/messages/like/this " as commands.
Explicitly mark user interaction when inserting smilies from the toolbar so "Undo" correctly removes these smilies.
Clicking "New" or "Saved" in the status selector menu while typing a status message no longer keeps the status entry area stuck in "typing" mode forever.
Show tooltips for ellipsized conversation tabs. On older systems, tooltips will show for all tabs.
