alt Hacker News> Get rid of the pseudo SemVer where you can deprecate functions and then break in minor releases.
I agree, but I think there's a bigger, cultural root cause here. This is the result of toxicity in the community.
The Python 2 to 3 transition was done properly, with real SemVer, and real tools to aid the transition. For a few years about 25% of my work as a Python dev was transitioning projects from 2 to 3. No project took more than 2 weeks (less than 40 hours of actual work), and most took a day.
And unfortunately, the Python team received a ton of hate (including threats) for it. As a natural reaction, it seems that they have a bit of PTSD, and since 3.0 they've been trying to trickle in the breaking changes instead of holding them for a 4.0 release.
I don't blame them--it's definitely a worse experience for Python users, but it's probably a better experience for the people working on Python to have the hate and threats trickle in at a manageable rate. I think the solution is for people like us who understand that breaking changes are necessary to pile love on doing it with real SemVer, and try to balance out the hate with support and
I had a client who in 2023 still was on 2.7.x, and when I found a few huge security holes in their code and told them I couldn't ethically continue to work on their product if they wouldn't upgrade Python, Django, and a few other packages, and they declined to renew my contract. As far as I know, they're still on 2.7.x. :shrug:
That’s probably true. I do think part of the anger is that a lot of the changes didn’t clearly improve the code around it. The obvious example is the change to print from a statement to a function. It makes the language a little cleaner, but it also breaks existing code for little practical benefit. More insidious was the breaks with strings and byte strings. It was a good and necessary change that also could lead to weird quiet breakages.
At least for me, the real blocker was broad package support.
Maintainers should think carefully about whether their change induces lots of downstream work for users. Users will be mad if they perceive that maintainers didn’t take that into account.
