Python 3.13.1 | Released Today

The free-threaded future is coming. The JIT is coming. But today, we got a quieter gift: a Python that crashes less, pastes correctly, and respects your terminal.

Let me cut through the noise and tell you what actually matters. Python 3.13.1 is a bugfix release — the first in the 3.13 series. If you're running 3.13.0 (released October 7, 2024), you'll want this update. If you're still on 3.12 or earlier, this isn't your cue to upgrade just yet, but it's worth knowing what's coming. python 3.13.1 released today

The team is effectively saying: "We'll push major features, but we'll clean up fast."

3.13.1 arrived just after 3.13.0, compared to the typical 90–120 days for past .1 releases. Why? Because 3.13.0 shipped with more experimental flags ( --disable-gil , --enable-experimental-jit ) than any release in a decade. Each flag is its own parallel universe of bugs.
