The deadline for inclusion in TeX Live 2009 is approaching (some time in May, I think). I’ve got a few things I’d like to get in, so they are keeping me busy. The updates to rsc, achemso (which had a bug fix today) and trivfloat should all be included, and I want to fix one thing in siunitx and look at some chemstyle issues. As well as that, there have been some things for LaTeX3 to get sorted out: it now includes a new “messages” module l3msg. So work on siunitx version 2 is currently a little delayed. Hopefully I’ll get back on to that next week.
