Python 3.12 was released a month ago, and it's time to prepare for the 
update in unstable, first adding 3.12 as a supported version.


There s a tracker for adding 3.12 as a supported version [1], also there 
are the first bug reports filed for issues related to 3.12 [2].


As usual, it's difficult to find about issues in higher stages before 
building packages in lower/earlier stages of the transition.  Therefore 
we started again adding 3.12 in Ubuntu, and then filing and fixing 
issues in unstable before adding 3.12 in Debian unstable.


This Ubuntu tracker can be seen at [3]. Note that i386 is only a partial 
architecture, and that Ubuntu doesn't run the tests on riscv64 during 
the build (so packages succeeding to build on riscv64 but not on the 
other architectures most likely show test failures instead of build 
failures).


Ubuntu's update_excuses for python3-defaults also shows autopkg tests 
failing with 3.12 supported, although this information is a bit out of 
date, due to infrastructure issues for the autopkg testers.


The plan is to make 3.12 supported in unstable at the end of November, 
or earlier if possible, so that other transitions aren't blocked by the 
addition of 3.12. Then planning for the defaults change in January.  
While this timeline is not that much needed for 3.12, it will be a good 
exercise for 3.13, so that we get 3.13 as the default into the trixie 
release.
