+## [UNRELEASED]
+
+### Added
+
+* Added a button to issue/PR/commit messages that updates the embed with the latest details.
+  * For example, if you run `/gh issue issue:1`, and then the title of issue #1 is changed, pressing the refresh button will edit the embed title to match the new issue title.
+  * This button can only be used once per minute by unauthenticated users (calculated using the message's last edit time).
+
+### Changed
+
+* The "Show GitHub issues" message command now includes the issue description if the message only contains one issue reference.
+
+### Notes
+
+* The previous release should have been `0.3.0` instead of `0.2.4`, since a new feature was added.
