 - `conftest` since `0.60.0` has moved to use rego `v1` as default. To continue using `v0` use `--rego-version v0`. For more information about upgrading to Rego v1 syntax, see the [upstream docs](https://www.openpolicyagent.org/docs/latest/v0-upgrade/).
 
+- Zig 0.12 has been removed.

 - `stalwart-mail` since `0.13.0` "introduces a significant redesign of the MTA’s delivery and queueing subsystem". See [the upgrading announcement for the `0.13.0` release](https://github.com/stalwartlabs/stalwart/blob/89b561b5ca1c5a11f2a768b4a2cfef0f473b7a01/UPGRADING.md#upgrading-from-v012x-and-v011x-to-v013x).
 
 - Greetd and its original greeters (`tuigreet`, `gtkgreet`, `qtgreet`, `regreet`, `wlgreet`) were moved from `greetd` namespace to top level (`greetd.tuigreet` -> `tuigreet`, `greetd.greetd` -> `greetd`, etc). The original attrs are available for compatibility as passthrus of `greetd`, but will emit a warning. They will be removed in future releases.
