Release Notes

astral-sh/ty (astral-sh/ty)

v0.0.39

Compare Source

Released on 2026-05-22.

This release removes the Python 3.9 branches from our vendored standard library stubs. ty now only has "full" support for
Python 3.10 and later, but will still report version-specific syntax errors and other diagnostics when --python-version 3.9
is provided via the CLI.
