Stubtest errors

These are currently ignored in a dedicated "allowlist":

Once this isn't needed anymore; scipy-stubs can be considered to be compatible with scipy 1.15.0[rc1]

Looks very organized! In case it isn't obvious, I may be slightly delayed on the exact days for branching and RC1.

Looks very organized!

Thanks :)

In case it isn't obvious, I may be slightly delayed on the exact days for branching and RC1.

No problem!
I'll try my best to sync the scipy-stubs 1.15.0.0 with the scipy 1.15.9 one as much as possible. And I expect that the RC window of 4 weeks should be more than enough for that 👌🏻.

[jorenham]

everything appears to be valid with 1.15.0rc2 now, too 👌🏻
