I just noticed that the amsmath package was updated lately. Sadly, I am unable to find the package history? texdoc amsmath does not seem to help and the documentation available online seems limited.

The amsmath changelog has always been in the README linked from
https://www.ctan.org/pkg/latex-amsmath
so I kept to that for now at least.
changes since 2000 are

2016-03-03 amsmath.dtx 2.15a
One missing % added to mathstrut handling.

But updating typesetting features of amsmath is a delicate topic that does not just affect one or two users.
