as the title says. I think the only way to study the new features is to read release logs.
I don’t think you can, but here’s links to:
2.34 release log
2.33 release log (2.33a bugfix list)
2.32 release log
2.31 release log
<gap in the currently online release notes for which I can’t find any info>
2.25 (“Blender Publisher”) release notes (.pdf)
The release notes from 2.26 to 2.30 are stored as text files in CVS.
I’ll download the releasedlogs page by page (everytime, the links to pics make my ie/myie halt for several seconds :< ) and try to learn cvs.
