Subject: [PATCH] Fix release drafting and pending release alerts (#770)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* Fix gitlab release drafting script

Don't scan commit body for PR-like commit messages. Fix warnings from linter,
and take object URL for signing verification from /git/ref/tags rather than hard-coding

* Temporarily Disable GPG verification in pending...

...release alerts. GPG verification of objects is also done before creating the
draft release so this isn't as bad as it sounds

* Temporarily Disable GPG verification in pending...

...release alerts. GPG verification of objects is also done before creating the
draft release so this isn't as bad as it sounds

* Remove accidental GH token leakage 😅
