Heads-up: python-typeguard 4.0.0 coming to Rawhide

[Ben Beasley]

I plan to update python-typeguard from 2.12.3 to 4.0.0[1] in Rawhide.

Version 3 of typeguard included a number of breaking changes[2], and 
4.0.0 included a few as well[3].

Directly-dependent package compatibility with version 4.0.0 is as follows:

     - python-nptyping is compatible

     - python-signature-dispatch will be compatible with a concurrent 
update from 1.0.0 to 1.0.1[4]

     - python-stack-data has dropped the dependency in Rawhide

     - python-TestSlide is incompatible, but (1) the package already 
FTBFS in F38 and Rawhide, and (2) I opened PR’s to fix the existing 
FTBFS[5] and typeguard 4 compatibility[6] about a month ago. The 
maintainers can easily fix the incompatibility whenever they want to 
address the existing FTBFS.

While the Updates Policy prescribes one week’s notice for 
API-incompatible updates like this[7], the intent of that rule is to 
avoid breaking packages without notice. In this case, python-typeguard 
already FTBFS in Rawhide since python-typing-extensions was updated from 
4.5.0 to 4.6.2, and this incompatible update is required to fix that. If 
the package is not updated, python-typeguard and everything that 
directly or indirectly depends on it will fail in the Python 3.12 mass 
rebuild.

I have therefore asked FESCo for permission to update immediately rather 
than waiting out the usual one-week notice period.[8]
