This month is fruitful with new packages to collection and update-add listen is touching 55 count.

Due to Pandas 3 landed on the python-team branch, we need to be prepared - #Astropy is bumped to 8.0.0rc2 to support it.

Having fresh Pandas is a great thing, but having everything working again is another goal for the current #guixpythonteam cycle

#Dask has been refreshed without any issues
#Modin needs some love, but it looks like there is no open PR bringing Pandas 3 compatibility upstream

Moving slowly for Cython/NumPy stack refresh in #Guix about 200 on the list with 1-30%

Pandas 2 failed 20 tests, but v3 is out there, time to refresh -- help wanted

Scipy passed all 8k tests on the latest refreshed version.

Ending spring with new blossoms of Python freshness, and it queued to QA
