- Python 3.14 is now available with new features like template strings (t-strings) and free-threaded Python.
- Template strings (t-strings) offer a new way to interpolate values into strings, evaluating to a Template type instead of str.
- Free-threaded Python (no-GIL) is no longer experimental, improving multi-threaded concurrency.
- Python 3.14 introduces a new interpreter type built with Clang, offering a 3-5% performance boost.
- New syntax warnings for using return, break, or continue in finally clauses to prevent unexpected behavior.
- typing.ByteString and collections.abc.ByteString are deprecated again, with removal delayed to Python 3.17.
- REPL improvements in Python 3.14 include syntax highlighting and import autocompletion.
- Python 3.9 is reaching end of life, with Ruff v0.14 increasing the default Python version to 3.10.
- Ruff and uv have been updated to support Python 3.14, with new rules for t-strings and other features.
