Again, I checked and there is a considerable switch done from 9996 to 9997,
and that is:
* Unicode/OpenType math implementation now based on HarfBuzz's MATH
  table support, for easier ongoing maintenance.
The associated code changes are considerable (roughly:
 14 files changed, 197 insertions(+), 600 deletions(-)
)

That is not something I want to push to stable. 

Best

Norbert

It is not about the version differences, but about the amount of changes
introduced. Stable updates are considered very critical.

I will see what I can do, but that is a very vague promise ;-)

The unstable version is based on TL2017 already and will transition to
testing sooner or later.

Thanks

That doesn't look possible. Updates to stable are very rare, and in this
case we would need to push a rather uncomfortably large set of changes.

If there is a simple and confined patch to fix this, that would be fine,
but I don't see it.


Hi Norbert,

thank you for letting me know. That's unfortunate, although the 
difference in the last digit of the XeTeX version seems minor to me.


I guess, in this case feel free to view it as a bug report against the 
xetex version in testing... (I did not try to install the version from 
unstable/experimental so far, but if it is brand new, the bug is likely 
to be fixed there.)


Best,
Leon

Bug#865396: xelatex + unicode-math + \big = ↯

2017-06-20 Thread Leon Meier

Package: texlive-xetex
Version: 2016.20170123-5
Severity: minor

Details:
http://tex.stackexchange.com/questions/375355/xelatex-unicode-math-big

In short, the output of xelatex on

\documentclass{article}
\usepackage{unicode-math}
\begin{document}
\(\bigl[
,
  \mathchoice%
  {}%
  {}%
  {}%
  {\hbox{$\scriptscriptstyle a$}}
\bigr]\)
\end{document}

is buggy.

XeTeX Version 3.14159265-2.6-0.6 has the bug, and 
3.14159265-2.6-0.8 doesn't. Could you suggest the newer version into 
stable?
