 We follow Semantic Versions.
 
+## Version 0.0.3
+
+### Features
+
+- We now use `Z` as the default code for our errors
+- We have shuffled errors around, changing code and formats
+- Now all name errors share the same class
+- Adds `PrivateNameViolation`
+- Now imports inside any structures rather than `Module` raises an error
+- Adds `file` and `klass` as restricted names
+- Now `__import__` is just a bad function name, not a special case
+- Now version is defined in `poetry.toml` only
+- We now have configuration! And it covers all design errors
+
+### Bugfixes
+
+- Fixes issue with missing `parent`s :batman:
+- Fixes issue with `_$NAME` patterns being ignored
+
