+## [1.2.3] - 2023-08-06

+### Added
+
+- Added `update-game-ids` command to manually update the Game Title ID registry.
+- Added warning when Game Title ID registry is older than 30 days.
+
+### Changed
+
+- Game Title ID cache no longer expires, therefore is no longer considered cache and is now known as the Game Title ID
+  registry.
+- Game Title ID registry is now part of the project/package files and will be updated on each release.
+- Replaced usage of ImageMagick with Pillow; ImageMagick is no longer a dependency.
+
+### Fixed
+
+- Fixed API call within `get_game_title_ids()`, though it still sometimes errors with HTTP 500.
