But if you're a member when the update comes out you get the eZine that details everything that comes with the release. There's also other docs with info on what's been fixed updated and new features.
If you weren't a member for the release then it would be useless information. If you skipped the release you can't rollback. So just download the release and its info and decide if you do or don't want to install. You'll always get announcement on the forum that a new release is out.
Can you imagine in 12 months time all the stickies that would be on the front page with release info if each one was kept there.
