The first year of free-threaded Python
The first year of free-threaded Python
A recap of the first year of work on enabling support for the free-threaded build of CPython in community packages.

Why wasn't free threading a new version of python? Having everything suddenly going from thread safe to C level insecurity is a major change, not just a small feature update. In fact, if they had to redactor the interpreter to support it, that sounds like even more of a reason to make it a major version update. Doesn't python follow semver?
The free-threaded build is a patched version of the interpreter. This is not (currently) behavior normal users will be exposed to.
Why wasn’t free threading a new version of python?
It was part of the 3.13 release.

Sure, which is why it this behavior currently considered experimental and is not enabled by default; if you want to try it out, you have to specifically enable it when building Python from sources.

No, currently releases follow a regular schedule and every release bumps the second number and keeps the first.
