After installing recent updates to
l3kernel and packages (both packaged 2012-07-19) on my MikTeX 2.9 system, several things seem to have broken:
- docs relying on
unicode-mathno longer compile properly (math fonts all upright, not italic)
chemnumalso seems to have stopped functioning properly
So, beyond the specifics of the issue, when this sort of thing happens, what is the preferred course of 'reporting' such a problem? is there a way to get older versions of a package, to 'roll back' to confirm that the problem originates with the 'newest version' of a package?
Quick additional comment: although not a rigorous test - a colleague who is 'celver' enough not to have update l3kernel and l3packages reports no problem with compilations. Again, not rigorous, but consistent with my working hypothesis that l3kernel and l3packages updates are the culprit.
