The team is back from the holiday break, and the weekly Preview release rhythm has returned! Preview 2 of 4.11 is now available on the launcher and includes a number of fixes found by Epic and the community.
To get started, head to the "Library" section of the Unreal Engine tab in the Epic Games Launcher, select "Add Versions", and choose 4.11 Preview 2. If you have an existing 4.11 Preview installed, you can hit the upgrade button whenever you're ready.
For more information on the fixes included in the release, check out the update from Stephen Ellis on the Unreal Engine forums, and be sure to read up on the known issues list. As a reminder, the Preview builds are for testing only, and should not be used for the active development of your project.
