A desync bug was found in 1.4, so we're moving forward to the next stable release rather quickly.

The desync was fixed, along with a number of other issues. Have a look at the changelog for details.

As normal, please test this version, in particular in multi-player (MP) to check that the desync got solved. You can download the new release now.

If you find any problems, please report them to our bug tracker.
