I must have seen the 2015/10/01 announcement but I was busy on 
other things, nevertheless I was only half surprised when bug reports

(*) one, so far

no wonder then that I when I started looking for info on the luatex
side I found none

(also I do not keep for a long time the messages I receive from
my subscriptions to mailing lists)

thus the fix will be easy and I will be able to push immediately to CTAN
a patched mathastext
