Re: ActiveResource (was: [ANN] 1.1.3 available.)

Where can I find info about the “CRUD/resource-based features” that will be
in 1.2.0?

In blogs. Especially about Railsconf and DHH’s keynotes.

In trunk : http://dev.rubyonrails.org/browser/trunk/activeresource

In DHH slides :

Transcription of some slides from DHH’s talk at RubyKaigi 2006
