Hi,

I'm about to file ~40 bugs for autopkgtest regressions with NumPy 2.4.
Most of them are caused by expired deprecations. You can find them in 
the release notes together with their suggested replacements [1]. The 
most prominent ones seem to be the `trapz` function (replaced by 
`trapezoid`) and attempts to cast arrays to scalars.

I am going to file the bugs with severity "important" and wait a couple 
weeks before uploading to unstable and raising bugs to "serious". A DD 
list is attached.

I know these kinds of updates, while unavoidable, create some annoying 
churn. I tried to keep the disruption small by waiting for a few patch 
releases which fixed a bunch of regressions in NumPy already. Feel free 
to contact me or reply to this thread if any unexpected issues surface.


Cheers
Timo
