 - Bumped the SenseGlove Unreal Engine Marketplace Packager to `v0.6.1-85c5a6e`.
 - Bumped the copyright years.
 
+### Removed
+
+- Dropped support for Unreal Engine `5.4`, which was already deprecated via the `v2.7.x` release series.
+- Dropped support for Epic Native/Cross Toolchains `v22` (previously used for building UE `5.3` and `5.4` Linux dependencies), as they were already deprecated via previous releases.
+
 ### Documentation
 
 - Ensure deterministic dependency builds by pinning Rust toolchain.
