+## Changelog
+
+### v1.1.0
+
+* Replaced status checks with an automatic bot review. If the PR title fails to match the regex, the bot will request changes. Once the
+title is edited to match it, the bot will dismiss its review.
+* Updated all dependencies.
+
+### v1.0.0
+
+* Initial release. This version uses action status checks but suffers from https://github.com/MorrisonCole/pr-lint-action/issues/5 since the GitHub actions API treats different hook types as separate checks by default.
