Read about it
HERE (btw, that's a great PPC blog...so bookmark it and read it everyday!!)
Anyways, it's now WM5 supported, has a RAM reclaimer (sweet!) and gets your Opera/Netfront cache amongst other new things....
New Features:
* Support for Landscape/Portrait screen layouts on the fly.
* Reclaim Memory. It frees up memory used by currently running
programs, this can claim memory in terms of MB. (Results depends
on the programs running)
* New Memory Cleaning for:
1. Dangling Notifications
2. NetFront
3. Opera
4. Virtual Mobile Earth cache
5. Window Media DRM
6. \Temp
* New Menus for fast access to all dialogs. (Matches with WM5 user
interface)
