List of "Bug" Functionality?

[JacobBeaudry]

Hi there,

I was just wondering if there is a list of functionality that exists on KaTeX but not LaTeX that has been flagged as a bug (and so will likely be removed at some point)?

E.g. Because of an issue with backslashes being escaped on our initial setup, I was using \cr[#pt] instead of \\[#pt] for setting spacing of aligned environments, so tons of the content I've written was broken when our programmer updated to a newer version (I'm not a programmer, so I'm not very familiar with GH's setup and am not 100% certain when this particular fix was merged - it looks like it might've been in Sept.).

This isn't a big deal, in this particular case, as I can just map \cr[#pt] to \\[#pt] using a renewcommand for now, until I can replace all uses in the code, and it's 100% on me -- I should've checked the expected functionality for \cr in LaTeX -- but I would like to avoid similar issues, in the future, if possible, so was wondering if there is a special tag for "behaviour that diverges from LaTeX that results in additional functionality that should not be used" or something along those lines?
