 ## Next Release
 
+### Remove Support for targeting Python 3.8
+
+Mypy now requires `--python-version 3.9` or greater. Support for only Python `3.8` is
+fully removed now. Given an unsupported version, mypy will now default to the oldest
+supported one, currently `3.9`.

+
+### Initial support for Python 3.14
+
+Mypy is now tested on `3.14` and mypyc works with `3.14.0b3` and later.
+Mypyc compiled wheels of mypy itself will be available for new versions after `3.14.0rc1` is released.
+
+Note that not all new features might be supported just yet.
