 All changes to Catstodon that aren't Mastodon or glitch-soc Mastodon changes will be documented here.
 
+## [v4.3.0-alpha.3+glitch+cat+1.2.7] - 2024-05-29

+- Upstream changes
+- Add ability to disable the suspicious sign-in detector
+  - The CatCatNya~ production config has an IP retention period of one day. That will cause suspicious login emails to
+    be sent out simply because we don't have any known IP data. Therefore, this fix is being applied.
