When a PR completely solves a problem described in an issue, you should use one of the keywords described here in the PR description and/or in the commit message merged to main:

https://docs.github.com/en/issues/tracking-your-work-with-issues/using-issues/linking-a-pull-request-to-an-issue#linking-a-pull-request-to-an-issue-using-a-keyword

eg, "Resolve #XX". This will automagically close the linked issue

"Addresses" here just created a "finglis mentioned this issue" link from issue 2001 to here.

Ah yes, I use 'fixes' and am generally pleased when it works - had never seen the list of possible keywords.

('Addresses' is still good for when you don't want the issue to close automatically though... since I'm not sure what 'Partially fixes' would end up doing)

It's a fairly dumb regex, so even "does not fix" will probably close the issue. Yes, I prefer "addresses" or "relates to" when the issue will linger on, although any mention will link the issue

technically speaking commit messages should be imperative, so one would prefer "resolve" over "resolves" although I find it more intuitive to use the indefinite present (?) form of "resolves"
