Features for release planning
For planning of the FLOW3 release (and other releases) we need some aggregated views.
Similar to "Versions" which can be set for a project, we need some new data type "Release" which has the following properties:
- version number
- name / label
- projects which are involved in this release
- version numbers of these projects
- wiki page for that release
then we also need a (probably read-only) aggregated view of the issues of all projects / versiosn involved in the release.
