Hi everyone, I've put in support for 1D and 2D data in yt/trunk. It's currently not well-documented, or documented at all, but you should be able to slice along axis '2' for 2D data and you should be able to add_ortho_ray to a PlotCollection for 1D data. Additionally, support for dx!=dy!=dz has been shored up, and support for non-cubic domains has also been improved. There may still be funniness there. The biggest change, though, is the generalized field containers. This probably won't mean much to you unless you do a lot of work with your own custom fields; it should be completely compatible with what you currently do, but if there are problems, let me know. The new generalized field containers allow for different sets of fields based on the type of StaticOutput and Hierarchy created; if you have a particular set of fields you are always adding, or modifying existing fields, it might be worth your time to subclass EnzoStaticOutput and set up your own field container. Again, this is mainly just a feature enhancement notice, but if you are running off trunk and you run into problems with fields, let me know. If you're running off yt-1.0, which you are if you installed from the Enzo 1.5 sources, then none of this should affect you. -Matt
