Here are expedited security releases of Python 3.15 and 3.14, and a special security release of 3.13.
They all upgrade the bundled pip to version 26.2.2, which includes certifi 2026.10.19 to address the eMudhra / emSign CA certificate security incident.
We don’t normally update pip for security releases like Python 3.13 because of backward compatibility concerns, but since 3.13 only just entered security-only mode, doing a special release with installers seemed prudent.
See the Discourse announcement for more information.
For all existing virtual environments on your system, please upgrade pip and uv to the latest versions.
To upgrade pip securely within a virtualenv:
python -m pip install "pip @ https://files.pythonhosted.org/packages/3f/06/3e4420302363fbb71be3c7f35ce042f54bfca330e3e66b3a2e3c4cca579f/pip-26.2.2-py3-none-any.whl#sha256=fd7f4dfa8190e014013b9f08f3e973f4e4c26ffd179a204895533a7254813a70"
If you cannot immediately upgrade to this release, you can upgrade certificates for a Python 3.15 macOS installation and pip itself via:

macOS 27.0 IDLE and tkinter
Additionally, the macOS installer for this release is built with a pre-release of Tk, fixing a possible hang on macOS 27.0 in applications using tkinter, like IDLE, in older releases.
