 - Add `dependency_hash` method to the `environment` interface
 - The state of installed dependencies for environments is saved as metadata so if dependency definitions have not changed then no checking is performed, which can be computationally expensive
 - The `build` command now supports backends other than Hatchling
+- Allow the use of `features` for environments when `skip-install` is enabled
 - The default is now `__TOKEN__` when prompting for a username for the `publish` command
 - Bump the minimum supported version of Hatchling to 1.17.1
 - Bump the minimum supported version of `click` to 8.0.6
