I don't mean to belabor the point, but my first try at the woven tutorial example produced a DeprecationWarning as part of its traceback. My first thought seeing that was that I probably needed an *earlier* version of Twisted, rather than a *later* one, to make the example work.
As it turns out, that warning was misleading, since I was apparently using an older Twisted version with a newer server script. I'm not going to bother sorting out exactly what is deprecated, current, and phased out... but I think I've figured out enough to determine that Glyph has the better advice: less than everything stays backward compatible.
