The Andoid dev team has released the SDK for the version 2.0.1 of the Google mobile OS. Just as the naming suggests Android 2.0.1 is a pretty minor update to the 2.0 including several bugfixes and behavior changes.
There is also an update to the Android 1.6 SDK component. Revision 2 includes fixes to the compatibility mode for applications that don’t support multiple screen sizes, as well as SDK fixes.
Here’s the link to the complete changelog.
