The recent change in the MathJax rendering engine broke quite a few of my older posts in which I used \\[ and \\] for delimiting displayed math. I'm used to using \[ instead of $$ in my LaTeX-documents and thus did this here, too (by the way, this is in accordance with the suggestions of this question on tex.SE).

It appears that this isn't rendered properly anymore, see e.g. here or here among many others.

What should I do about this issue? I'm a bit reluctant to fix this myself manually (admittedly, laziness on my part is not the least of reasons). Is there an easy fix or should I simply ignore it?

PS. I became aware of this issue due to an edit of Didier Piau to one of my older answers (thanks for that, by the way!).

I added \[ as a Mathjax delimiter, it was missing in the latest upgrade. This should go out with the next build.

  • $\begingroup$ Ah, not quite perfect, though. Shouldn't it be a displayed math delimiter instead of just a math delimiter? The posts are human readable again, but the intent of using \\[ clearly is to get a displayed math environment. $\endgroup$
