Snow Leopard to your Leopard -- this release contains some improvements and bug fixes to v8. Notably, niv-updater-action now properly handles repositories whose main branch is main, offers better handling of various SSH links to GitHub repositories, and finally, fixes an annoying problem with self-updating PRs, where update would fail unexpectedly*.
[*] Unexpectedly is defined as in: niv-updater-action was using hub pr command to fetch PRs branch -- that doesn't work without a checkout, so it would fail almost every time if the action was not preceeded by a checkout action. Which it was not, at least not in the examples given.
