At this stage, there are likely to be some bugs and other annoyances in the code. However, I hope that enough works for people to risk taking the plunge and trying it out. For those willing to try out siunitx v2.0, you can get:

• The ready to install TDS-style zip file
• The package documentation
• The source file (dtx)

You’ll need to have up to date installations of both expl3 and the xpackages to try out the code, as internally the new code uses the LaTeX3 internal syntax. The biggest change that users should see from version 1 is that I’ve re-thought the option names. They are mainly longer, but more informative, in the new code. Improvements to the names I’ve picked are of course welcome.

At this stage, I’m still working on adding more ideas to the code. So there are some omissions in the release that I know are there and am intending to sort out. Of course, different users have different priorities for improvement. That said, there are bound to be things which simply are broken, things I’ve forgotten and the odd item that I’m currently planning not to carry forward from version 1. Feedback by as comments here, by e-mail or at the BerliOS site is very welcome.

The current development plan is to see how much is wrong with the alpha code, and if necessary to have some more alpha-status snap shots. I’d then hope to have a beta some time in the spring (perhaps April or May), with a full release currently in my mind for June or July. Exactly how this will work out depends on other projects: I’d like, for example, to have some floating-point tools in siunitx, but for that I need to write them for LaTeX3. The feature list for the release certainly isn’t fixed, and I’d expect that once v2.0 is out there will continue to be more ideas to add on.
