+## [2.2.1] - 2023-01-16
+
+Added official support for Python 3.11. No changes were actually made to do this, and most all previous versions of pytiled-parser should work fine with 3.11. We are just now including 3.11 in the matrix of Python versions we run tests for.
+
+Improved compatibility for pre-1.0 Tiled JSON formats([#65](https://github.com/pythonarcade/pytiled_parser/pull/65)). This does not necessarily mean we guarantee support with older versions of Tiled, support for older versions will be on a best effort approach.
