 # Changelog
 
+## Version 0.9.0
+
+This version adds the ability to `inherit` in override tables, matching a
+similar feature added to cibuildwheel 2.17's overrides. You can now write out
+extra metadata to `@{SKBUILD_METADATA_DIR}`. A new Hatchling plugin is provided
+as an experimental feature (will likely be made a separate package in the future
+like the setuptools plugin).
