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-math
no longer compile properly (math fonts all upright, not italic)
see - Cambria Math becomes plain Cambria
chemnum
also seems to have stopped functioning properly
see- Chemnum does not work since last l3package udpate
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.
unicode-math
) is aware of the update and I am sure will update the CTAN version in a few days. As noted in the linked thread,chemnum
has already been updated on CTAN. My ownsiunitx
has already been updated on CTAN to use the updatedl3kernel
code, and to check that it is in use. Keeping packages absolutely 'in sync' is always tricky as synchronised release to CTAN does not guarantee the same will happen in TeX Live or MiKTeX.make localinstall
: the log shows when we are sending snapshots to CTAN.
