There are also a couple of fixes in the repo (mainly performance improvements) so I should do a beta 5 as well.

Jeepers I came across as even more of an asshole than usual in that email. Anyway, doc patches would help - but I need to rewrite the examples to use the new 0.8 features, as some of it is now idiomatic for stuff that is pretty common. So it isn't *just* a case of adding the new features to the docs.

I'll try and get to it over the Christmas break. (I actually enjoy writing docs - but have been really short of time recently.)

Maybe if I do a 0.8 beta 5 release I should just do a full pypi release with it - at least that would get more people testing the new code... ;-)

All the best,

Michael

May you do good and not evil
May you find forgiveness for yourself and forgive others
May you share freely, never taking more than you give.
