This is a pretty big upgrade from the previous version, i highly recommend upgrading.
The entire core and several other parts have been rewritten completely.
Some of the new features are, experimental scripting support, log browser/viewer and a channel editor.
See the release notes for more information.
Thanks to all the beta testers and bug reporters, keep it up :)
