No GIL, and JIT enabled (even if experimental), kudos to the team.

New features * PEP 779: Free-threaded Python is officially supported * PEP 649: The evaluation of annotations is now deferred, improving the semantics of using annotations. * PEP 750: Template string literals (t-strings) for custom string processing, using the familiar syntax of f-strings. * PEP 734: Multiple interpreters in the stdlib. * PEP 784: A new module compression.zstd providing support for the Zstandard compression algorithm. * PEP 758: except and except* expressions may now omit the brackets. Syntax highlighting in PyREPL, and support for color in unittest, argparse, json and calendar CLIs. * PEP 768: A zero-overhead external debugger interface for CPython. UUID versions 6-8 are now supported by the uuid module, and generation of versions 3-5 are up to 40% faster. * PEP 765: Disallow return/break/continue that exit a finally block. * PEP 741: An improved C API for configuring Python. A new type of interpreter. For certain newer compilers, this interpreter provides significantly better performance. Opt-in for now, requires building from source. Improved error messages. Builtin implementation of HMAC with formally verified code from the HACL* project. A new command-line interface to inspect running Python processes using asynchronous tasks. The pdb module now supports remote attaching to a running Python process. More details: https://docs.python.org/3.14/whatsnew/3.14.html https://docs.python.org/3.14/whatsnew/3.14.html

I've created a library that use t-strings to prevent shell injection that even works on Windows. It's written in Rust. https://github.com/aspizu/tshu https://github.com/aspizu/tshu $ uv run --with tshu python -m asyncio >>> from tshu import sh >>> username = "aspizu; rm -rf /" >>> await sh(t"echo {username}") aspizu; rm -rf /

  Does the library handle arguments that begin with a dash? Does this code print out the contents of the file named `--help`, or does it print the documentation for the `cat` command? filename = "--help" await sh(t"cat {filename}")
