[Zope-Annce] Zwiki 0.57 released

[Simon Michael]

Good day all!

Zwiki 0.57 has been released. If you feel like it's been a while since 
last announcement, you're right. I have been in an intense phase of 
travelling, work hunting, adapting to a new job, and could not avoid the 
hiatus, for which I apologise. 

To be precise, in september, 0.56 was released but not announced on 
zope-announce; in august, 0.55 was released but not announced on 
zope-announce or zwiki.org; and in july, there was no release. Ack! Thus 
ends my four-year run of monthly releases. If you're interested in 
helping out with release management, or have ideas for simplifying Zwiki 
processes, get in touch.

Thanks for your support. Peace,
-Simon
