Refresh me please

I’ve been away from Blender for over a year. I have version 2.44, but have not worked with it all yet.
Is there a thread or a URL that would help me get up to speed on what’s new, and what’s no longer used in the UI?

(Forgive me Blendo, for I have coveted a different app for a while):no:

The release notes is a logical place to start:

Mystery

(blush)-- Thanks, I’ve not been very alert- should have done some thinking. :o
