-## [unreleased]
+## [v4.4.8] - 2022-05-10
+### Changed
+- You can now join with a team ID not appearing in `teamids.txt`, 
+  as long as it is registered (in the `teams/` directory)
+
+## [v4.4.7] - 2022-05-10
+### Changed
+- Initializing an instance now truncates `events.csv`
+
+## [v4.4.6] - 2021-10-26
+### Added
+- State is now cached in memory, in an attempt to reduce filesystem metadata operations,
+  which kill NFS.
+
+## [v4.4.5] - 2021-10-26
+### Added
+- Images deploying to docker hub too. We're now at capacity for our Docker Hub team.
+
+## [v4.4.4] - 2021-10-20
+### Changed
+- Trying to get CI push of built images. I expect this to fail, too. But in a way that can help me debug the issue.
+
+## [v4.3.3] - 2021-10-20
 ### Fixed
 - Points awarded while scoring is paused are now correctly sorted (#168)
 - Writing a new mothball with the same name is now detected and the new mothball loaded (#172)
 - Regression test for issue where URL path leading directories were ignored (#144)
+- A few other very minor bugs were closed when I couldn't reproduce them or decided they weren't actually bugs.
 
 ### Changed
 - Many error messages were changed to start with a lower-case letter, 
   in order to satisfy a new linter check.
 - CI/CD moved to our Cyber Fire Gitlab instance
+- I attempted to have the build thingy automatically build moth:v4 and moth:v4.3 and moth:v4.3.3 images, 
+  but I can't test it without tagging a release. 
+  So v4.3.4 might come out very soon after this ;)
 
 ## [v4.2.2] - 2021-09-30
 ### Added
