- [x] Does not require a CHANGELOG entry

We are trying to get the command bot working. However, right now it is
timing out when trying to build the runtimes plus the omni bencher after
6 hours. This should not take 6 hours ;) So, one guess is that maybe the
nightly is doing something that takes quite long to build. We want to
try the stable compiler and see if that fixes the issue.
