I updated PyLucid, so now it can be used with the current django trunk version ;)

Django changes are:

• newforms admin branch merged
• Moved django.newforms to django.forms
• Changed the way URL paths are determined

Needed PyLucid changes: changeset 1719-1723

pages updates:

• new page: update PyLucid from v0.8.x to v0.8.5
• insert install instruction into /documentation/using/blog/
