The release of 3.0.14 of OpenProject contains several bug fixes. We advise everybody to update their OpenProject installation.
Most notably, copying projects works properly again. In the previous version it was not possible to properly copy projects either from the admin or project settings. This has been fixed with version 3.0.14 (#15706).
For a complete list of changes, please refer to the OpenProject 3.0.14 query.
