v2.0.1

What's Changed

• Support Python free-threaded builds (PEP 703). The extension now opts into the no-GIL ABI via Cython's freethreading_compatible directive, so it is loaded on python3.13t / python3.14t without re-enabling the GIL. All module state is set once at import and the encode/decode hot paths keep per-call state on the C stack, so the extension is safe to call from many OS threads concurrently. Bumps the build-time Cython requirement to >= 3.1. A new threaded stress test (scripts/run-threaded-test.py) is run in CI on every free-threaded build identifier produced by cibuildwheel.
