I just installed mate bionic. It's been a while since last install. Lots of changes and improvements since last installed. I did come to an interesting installed program/font: mathjax.
Googling revealed its much more than just fonts.
My question is what prompted the inclusion of 'mathjax', as it is in mate?
I did see this:
Drop support for win32, osx and hildon
Drop useless mate-icon-theme dependency
Drop embedded MathJax in favor of using a distribution packaged version
Make smclient mandatory
