ucw development has slowed down a bit recently (to be precise it's moved to other sub projects).
cl-icu is currently in a workable (even under cmucl!!) but un polished state. the next thing to do is create a yaclml and tal interface to icu (tags like <:current-time, <:current-date and <:currency-value which use the client's locale and icu to properly format the data).
the cps transformer (the base of all the action vodoo) has undergone a major rewrite. it's now much more complete than it was before and much easier to read and modify and tramploines so that stack overflowing is no longer a problem. it can even transform and run itself (but don't try and read the output of that).
as far as ucw itself: i'm currently refactoring the request<->response loop code trying to make it easier to understand and extend. to goal of this is to add action transactions, and should happen shortly. before that however the distinction between named actions and actions will be removed, we'll simply use a builtin function to handle actions, this will allow a lot more flexibility in where to send action requests to and greatly simplify the request response loop (basically we won't have any special cases).
