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.

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.
