By the way, you don't need to update the changelog at all in PRs. When doing a release, I just do
gh search --prs --merged --repo wasmerio/wasmerand then copy the list since the last release. Otherwise I'd have to look if every PR has included this message. So this commit is nice, but pointless.There was a problem hiding this comment.

Ah okay. We should probably update the pull request template so we don't tell people to update the changelog.
