Release Notes

This is the fourth public release of Woof! and is intended to allow people to try out Woof! and provide early feedback. The API is stabilizing but still subject to change.

Unfortunately, Woof 0.5 has some incompatibilities with previous versions. The page layout system in particular has been changed due to the underlying YUI CSS libraries no longer being developed by Yahoo.


See for install instructions. Upgrades are not yet supported.
