Parallels Desktop Mac 2.2 released!
Parallels Inc. has released the newest build of the software on their Release Candidate update page
. The main page will probably be updated to reflect the final status of the release later on. The build fixes various issues, kernel panics among them (although I haven't met any with previous builds) and improves performance. It also lets Vista RC1 live as a guest OS (previously only Beta 2 worked).
Parallels also announced that a new RC build would follow in about two weeks to solve the problem for 64bit Macs with more than 2 GB of RAM. In the current version, users have to restrict RAM to 2 GB through an included tool.
