I have just pushed ist.js version 0.5.6 to GitHub. This version fixes a bug that prevented building (with r.js) projects when using the ist! requirejs plugin syntax.

I'm sorry for the lack of updates lately; I'm currently working on ist.js v0.6, which will allow updating rendered nodes with a new or modified context, introduce some new built-in helpers and enhance performance. I plan to add JSDoc to the code and rewrite tests to be more thorough, better organized and so that they can be automated (and hopefully get ist.js on a continuous integration server).
