unicode-math or lua-unicode-math?

Question

I just noticed the lua-unicode-math package.

Question

I compile all my .tex documents using lualatex and therefore my question is as follows:

What are the main differences between lua-unicode-math and unicode-math and when should I use which package?

well lua-unicode-math is new and experimental. So try it and report if you see problems ... — Ulrike Fischer

the new one should be noticeably faster but has only had a couple of days of public use testing, the old one is noticeably slower but has a couple of decades of public use testing, take your pick.... — David Carlisle

The plan here broadly is that lua-unicode-math will be the basis for kernel-level support for OpenType Unicode fonts 'at some point' — Joseph Wright

@JosephWright Thanks for the explanation, Joseph. Can I make you create an answer? Then I can accept it and "close" the question. — Svend Tveskæg

@SvendTveskæg Sure - I think a combo of the comments is the answer ATM — Joseph Wright

unicode-math is well established and publically tested for decades. lua-unicode-math is potentially the "future" but hat only little public testing.
lua-unicode-math will be the basis for kernel-level support for OpenType Unicode fonts 'at some point'.
lua-unicode-math should be faster than unicode-math.
