Just seen that this new update has been seeded to developers. The headline feature is the inclusion of a iClould beta, but has anyone noticed any other features? I really want to see if it improves RAM usage, and therefore battery life. 

Apple is so modern that they're releasing an update from the future!
I've heard that it's purely iCloud changes, not fixes to other problems or enhancements to existing features. I guess that'll come in 10.7.1 which does seem odd.
I only install updates that show up in Software Update, not some random online torrent or elsewhere. That's just asking for trouble.

10.7.2 is available to developers on the Apple website.
Because i'm SURE everyone here, who has loaded it, is a bone fide OS X developer who actually has reason to load 10.7.2 before 10.7.1 is even released.![]()
I installed 10.7.2 today. Yes, it has an updated iCloud Preferences pane and, yes, the RAM usage is significantly less. On the GM I had about 4/8GB free. Now, I have nearly 6/8GB free.
Good news on the ram usage.
Right, but your original post made it sound like this was some sort of shady beta that had accidentally leaked onto the internet.
I've read some people reporting that memory usage was improved.![]()
It upgraded graphic card drivers, so it's not just iCloud.
