@bbhtt you can add dependabot to https://github.com/aio-libs/propcache/blob/master/docs/spelling_wordlist.txt.

Also, I just now noticed that the change log looks like a TODO-list or a Git log. Instead of the imperative mood of things to implement, let's update it to what's changed since the previous release by using the past tense of a present comparison ("X now does Y", "X has been changed to Y", "Updated X to Y").
