SimplyRestfull ? Where to download the latest version ?

Nuno,

  The REST functionality provided by the simply_restful plugin has
been in edge for quite some time now. The plugin was a testing ground
and now is simply of historic value. Simply rake rails:freeze:edge or
wait a few days/weeks for Rails 1.2 to be released.

Hope this helps.

Nuno,

Yes, edge rails is the latest copy from the trunk of the rails svn
repository. If you're just starting a project I would say it's safe
if only because rails 1.2 should be coming out shortly. At that point
you can freeze to 1.2.
