The title is referencing this line (not TFA's actual title):
> In the unittest module, a number of long deprecated methods and classes were removed. (They had been deprecated since Python 3.1 or 3.2).
I doubt your projects are using 3.1 or 3.2 (or older, except perhaps 2.7, but then you wouldn't care that 3.12 was removing something deprecated vs 3.11 which has it)?

#5The changes seem to be in modules.
What is the relation between a new Python version and changes in modules?
Are some modules considered to be part of the language?

The stdlib is linked to the version of the language, yes.

They're in the standard library, like `std` or (ish) Node API, etc.

I tried out teyit when it was a "Show HN" 10 months ago (at https://news.ycombinator.com/item?id=29948813 ).
It not only pointed out places where I was using a deprecated alias, but also fixed a few places where I was using the API poorly (using "assertTrue(a binop b)" instead of "assertBinOp(a, b)".
I recommend it.

#9The changes seem to be in modules. What is the relation between a new Python version and changes in modules? Are some modules considered to be part of the language?
Those modules are parts of the standard library.
As far as CPython is concerned, most of those modules are implemented in C, and therefore for practical purposes part of the interpreter itself.
> How can a language be released?
If we really want to be pedantic, a new version of the language spec can be released.
Translated to C++ terms, this is like if the ISO committee approved a change to the stl in the new standard.

#10While it's been coming for a long time, it's still frustrating to see the cgi module go. It's going to create a load of busy work to rewrite some low-traffic scripts.
Modules being removed [edit: in 3.13]: https://docs.python.org/dev/whatsnew/3.12.html#pending-remov...
Updating CGI scripts will be a bit fiddly: https://peps.python.org/pep-0594/#cgi
