[gkronber]

The relevant features from the branch should be merged to the trunk. Experimental features should be implemented in branches and tracked in separate tickets.

[gkronber]

Created follow up tickets: #1931, #1932, #1933, #1934. The feature branch should can be deleted when these tickets have been implemented.
