We’ve pushed the bits for Flex 2.0.1 to the Adobe site and you can – and should – grab it and install it.
We’d like everyone to upgrade to Flex 2.0.1. There are new features and fixes in this release.
You can read more about what’s in Flex 2.0.1 in Matt Chotin’s article on DevNet.
This upgrade is free. If you have Flex Builder 2, this will simply upgrade your install – it is not a new installation. Your license, projects, etc. are preserved.
