Known issue: Immediately after upgrading, users may have trouble loading Mono for Android projects. Please restart MonoDevelop again if you experience this.

Visual Studio Users: You should be prompted with this update when you open a MFA project. You can also check manually in Tools > Options > Mono for Android.

MonoDevelop Users: You should be prompted to upgrade next time you open MonoDevelop, or you can use Help > Check for Updates. IDE support requires MonoDevelop 3.0. Layout Designer fixes require MonoDevelop 3.0.4.

Warning: Samsung shipped a broken kernel with Android 2.1, which is not able to support JIT compilation. If you possess a Galaxy-class device with Android 2.1, you will get unexpected results, this is caused by a kernel bug that breaks cache coherency, rendering any engine doing JIT compilation useless. Check with your manufacturer/carrier for an Android 2.2 update.
