There’s security content in the releases, let’s dive right in.

- [gh-108310](https://github.com/python/cpython/issues/108310): Fixed an issue where instances of [`ssl.SSLSocket`](https://docs.python.org/release/3.10.13/library/ssl.html#ssl.SSLSocket) were vulnerable to a bypass of the TLS handshake and included protections (like certificate verification) and treating sent unencrypted data as if it were post-handshake TLS encrypted data. Security issue reported as [CVE-2023-40217](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2023-40217) by Aapo Oksman. Patch by Gregory P. Smith.

Upgrading is highly recommended to all users of affected versions.

## Python 3.11.5

Get it here:

> **[Python Release Python 3.11.5](https://www.python.org/downloads/release/python-3115/)**
>
> The official home of the Python Programming Language

This release was held up somewhat by the resolution of this CVE, which is why it includes a whopping 328 new commits since 3.11.4 (compared to 238 commits between 3.10.4 and 3.10.5). Among those, there is a fix for [CVE-2023-41105](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2023-41105) which affected Python 3.11.0 - 3.11.4. See [gh-106242](https://github.com/python/cpython/issues/106242) for details.

There are also some fixes for crashes, check out the [change log](https://docs.python.org/release/3.11.5/whatsnew/changelog.html) to see all information.

Most importantly, the release notes on the [downloads page](https://www.python.org/downloads/release/python-3115/) include a description of the Larmor precession. I understood some of the words there!
