Why you can’t switch to Python 3.10 just yet
Python 3.10 is now available–but should you switch to it immediately?
And if not now, when?
The short answer is, no, you probably don’t want to switch immediately; quite possibly you can’t switch immediately.
To understand why, we need to consider Python packaging, the software development process, and take a look at the history of past releases.
We can then make a guess about when Python 3.10 will actually be usable.
The problems with a new major Python release
I’m writing this article on October 5th, 2021, the day after 3.10 was released… and far too early to start using Python 3.10.
As with many open source projects, Python, Python libraries, and most of the toolchain and packages mentioned in this article are based on volunteer labor.
