When doing so you also benefit from a couple of usability bugfixes. Most notably, the preview functionality now works again throughout the application (#14775) and if you are using the the backlogs plugin it now shows the story points in the work package page (#7922).
With the integration of the repository-authentication plugin into OpenProject (#14783), it is now once again possible to manage authentication and authorisation of SVN repositories with OpenProject. The same will be allowed for Git repositories with OpenProject 4.0 (#3708).
For a complete list of changes, please refere to the OpenProject 3.0.11 query.
