Following the release of version 2 of siunitx, you might have noticed that there have been rapid minor updates (v2.0a, v2.0b and v2.0c). I thought I’d just say that most of this is to make sure that the version that ends up in TeX Live 2010 is as good as possible. There are the inevitable bugs to sort, especially with compatibility with version 1, and I want to get things working as well as possible. I suspect there will be a few more releases in quick succession!
