See issue #1402
I did NOT implement the usage for "Namespaced::Model.new.errors.add(...)" as I am a bit short in time currently. I basically brought back the changes from "jfirebaugh" in commit "5b8dbb0".
This means you can write your yaml file like this:
item: "Invoice::Item dot notation"
invoice/item: "Invoice::Item slash notation"
name: "Invoice::Item.name slash notation"
name: "Invoice::Item.name dot notation"
Brought back alternative convention for namespaced models in i18n.
I believe this one should be backported to 3-1-stable as well, because it's a bug fix.
3-1-stable pull request please? :)
This has been backported in #1562
