Currently behind paywall. But it includes this paragraph: -------- Improved support for math typesetting is hardly a surprise; TeX was originally created by Donald Knuth to help him typeset The Art of Computer Programming, and TeX is used heavily by math journals. Nevertheless, there is always room for advancement. LyX 2.1 improves on its formula-and-equation support by adding a document-wide "math font" setting (which will not get overwritten if one changes the font of other body text), by adding a unicode-math package that supports math OpenType fonts (such as STIX or XITS), and by adding a new inline "equation editor" mode. --------
I tried looking at my document settings/fonts, but I can't see what is meant: " by adding a unicode-math package that supports math OpenType fonts (such as STIX or XITS)" where would I see this feature?
