 A place for pydantic types that probably shouldn't exist in the main pydantic lib.
 
 See [pydantic/pydantic#5012](https://github.com/pydantic/pydantic/issues/5012) for more info.
 
-This is just a stub to reserve the name `pydantic-extra-types`.
+**Currently a work in progress.**
+
+This package will be officially released as V2 when pydantic V2 is released.
