+* **internal:** implement indices array format for query and form serialization ([97a9bb7](https://github.com/Mozilla-Ocho/tabstack-python/commit/97a9bb7241ad0c7a98483d81f74bbb5ee40e1b93))
+
+
+### Bug Fixes
+
+* **deps:** bump minimum typing-extensions version ([1946504](https://github.com/Mozilla-Ocho/tabstack-python/commit/194650472a951f76bd180e1dd08507fcf2670577))
+* **pydantic:** do not pass `by_alias` unless set ([a32962e](https://github.com/Mozilla-Ocho/tabstack-python/commit/a32962e54563d7073726b4463d70017fc2a40331))
