Today's #JetpackReleaseNotes include minor releases in Room 2.5.2, Compose Material3 1.1.1, and Annotation Experimental 1.3.1, but importantly is the first widespread set of releases that use a compileSdkVersion of 34 - you'll need to swap over as well!

With Android 14's API 34 being finalized, ~all new Jetpack library releases have started to compile with API 34. That means your app is also going to need to compile with API 34. Note that targetSdk is a whole different thing that you can do much later!

When it comes to Release Candidates, both Paging 3.2.0-rc01 and Wear 1.3.0-rc01 are out now! This is the perfect time to put them through the paces for any final bugs before their stable releases.

The alpha release I'm most interested in trying out is Room 2.6.0-alpha02 as it contains a new Room Gradle Plugin that replaces the need for annotation processor options and ensures reproducible and *cacheable* builds. 👀

@ianlake Are you gonna publish the android-34 source as well?
@coreflodev - after the final public release of Android 14, the source code for it gets pushed to AOSP. That's also when you can download the source via the SDK Manager.
