Mendix Business Modeler 4.4.3 and 3.3.6 have been released

We have released patches for version 3 and 4 of the Mendix Business Modeler this week. These versions contain fixes for issues reported by our partners. You can find both installers and the release notes on the App Store: 4.4.3 and 3.3.6.

Important Note: if you have upgraded to 4.4.0 or 3.3.5 or applied the manual Firefox 18 fix, we highly recommend upgrading to 4.4.3 or 3.3.6 and removing the manual fix. Read on for an explanation.
