The next update, 11.01r2, is ready for everyone to test. To get it, you have to opt-in to the public beta.
If you prefer the stable version of the sim, don't change anything and wait for the update to be declared final, at which point you will get it automatically.
For more information about the update, see the release notes: http://www.x-plane.com/kb/x-plane-11-01-release-notes/
