ArchiCAD 15 Hotfix #2 (Build 3602)

ArchiCAD 14 Hotfix #6 (Build 4204)

Here’s something worth reading now as well, from the release notes:

Notice to users who have both ArchiCAD 15 and ArchiCAD 14 installed

 ArchiCAD 14 Hotfix 6 (build 4204) should be applied together with ArchiCAD 15 Hotfix-2. This should be done,  to address Activity Monitor problems common to both BIM Server modules. These fixes will only be fixed completely if both modules are fixed simultaneously. To emphasize, you only need to apply this if you have the ArchiCAD 14 BIM Server module installed.

Follow the links to read more about each hotfix and download it. AND remember to update everyone using Teamwork 2 (including the BIM Server) at the same time.
