We have released version 13.2.20296.1426 on November 09th, 2020. This version is an upgrade release where the following bugs are fixed and new features are added or changed.

Important Information

If you have previously installed a beta version 13.2, please upgrade to the official release version 13.2.20141.1435 or later for support reasons!

As of version 13.2.20083.1640, a script for enhancing the address searching is included. These may cause the setup not to respond for a some time during database update. The setup must not be aborted and must run until completed. Please schedule a longer upgrade period for this.
