SDK 2.1.4, Eclipse plugin 2.2.0

I noticed these new upgrades:

-SDK 2.1.4
-Eclipse Plugin 2.2.0

Can we have any release notes for them?

I using Eclipse Luna Service Release 2 (4.4.2), and the software update is failing - "Cannot complete the install because one or more required items could not be found."

Anyone experiencing the same problem?
