+* **go:** upgrade golang to v1.20.4 and some deps ([#506](https://github.com/ArtalkJS/Artalk/issues/506))
+* **gravatar:** add `gravatar.params` config option ([#508](https://github.com/ArtalkJS/Artalk/issues/508))
+
+### Bug Fixes
+
+* **api:** comment IP data loss after editing ([#504](https://github.com/ArtalkJS/Artalk/issues/504))
+* **editor:** prevent editor reset on comment failure ([#507](https://github.com/ArtalkJS/Artalk/issues/507))
