Subject: Revert "Revert "Merge master into staging-next""

In 87a19e9048773d5a363679617406ad148d36c3b8 I merged staging-next into master using the GitHub gui as intended.
In ac241fb7a570d6cf81d229ad22a8889602639160 I merged master into staging-next for the next staging cycle, however, I accidentally pushed it to master.
Thinking this may cause trouble, I reverted it in 0be87c79797a5fa384fbc356c74ed54f9f7829ea. This was however wrong, as it "removed" master.

This reverts commit 0be87c79797a5fa384fbc356c74ed54f9f7829ea.
