 - `minetest` has been renamed to `luanti` to match the upstream name change but aliases have been added. The new name hasn't resulted in many changes as of yet but older references to minetest should be sunset. See the [new name announcement](https://blog.minetest.net/2024/10/13/Introducing-Our-New-Name/) for more details.
 
+- `poac` has been renamed to `cabinpkg` to match the upstream name change but an alias has been added. See the [new name announcement](https://github.com/orgs/cabinpkg/discussions/1052) for more details.

 - `racket_7_9` has been removed, as it is insecure. It is recommended to use Racket 8 instead.
 
 - `rofi` has been updated from 1.7.5 to 1.7.6 which introduces some breaking changes to binary plugins, and also contains a lot of new features and bug fixes. This is highlighted because the patch version bump does not indicate the volume of changes by itself. See the [upstream release notes](https://github.com/davatorium/rofi/releases/tag/1.7.6) for the full list of changes.
