What I've been surprised about is the number of python packages that require specific python versions(e.g., works on 3.10, but not 3.11. Package versioning is already touchy enough without the language itself causing it in minor upgrades.
And will python 3.14 be named pi-thon 3.14. I will see myself out.
Today someone's pipeline broke because they were using python:3 from Dockerhub and got an unexpected upgrade ;-)
Specifically, pendulum hasn't released a wheel yet for 3.13 so it tried to build from source but it uses Rust and the Python docker image obviously doesn't have Rust installed.
