Merging, s.t. this critical regression fix can still be part of the 2.081 release.

@wilzbach - I guess self merge means the bot won't auto-close the issues?

No, it has nothing todo with this.
The Bugzilla integration simply only closes issues when they are merged into master (people complained because they were getting many duplicated emails).
However, imho it's probably better to use "stable" instead as this will avoid the awkward situation that last-minute fixes aren't shown in the changelog (the changelog filters for only fixed issues).
OTOH it would also be awkward if the issues merged from master don't get auto-closed.
Anyhow, we have to replace this bit with the dlang-bot soonish as the GitHub Services are deprecated.

In case someone is interested here's how the config looks at the moment:
