Android Studio 3.1 Canary 3 now available

Android Studio 3.1 Canary 3 is now available in the Canary and Dev channels, and includes general bug fixes.

Known Issues:

Mac users: There is a known issue where you get the following error when building existing projects with this release. To resolve this issue, perform a clean build by first selecting Build > Clean Project from the menu bar.
    Execution failed …
    > v1 signature (JAR signature) not yet generated.

Kotlin Developers: When you build your project, you may encounter an error similar what's shown below. This is due to an out of memory exception from the Kotlin compiler daemon—even though your stack trace may indicate an end of file exception: java.io.EOFException. To resolve this issue, simply try to build your project again.
    Execution failed for task ':app:compileDebugKotlin'.
    > Internal compiler error.

If you already have an Android Studio build on the Canary or Dev channel, you can get the update by clicking Help > Check for Update (or Android Studio > Check for Updates on Mac). Otherwise, you can download here.
