In the guides for upgrading from Rails 3.0 to Rails 3.1, it would be helpful to document that the session_store key needs to be changed.
AppName::Application.config.session_store :cookie_store, :key => 'SOMETHINGNEW'
This migration step is also documented in this ticket #2509 (comment)
Come on, Nic, didn't you see we don't accept feature requests in Issues!
Regardless, I've pushed rails/docrails@1664093, which will take care of this for you. :p
Thanks for bringing it up. ❤️
I think it should be backported to 3-2-stable. This will go to edgeguides.
Open the pull request please.
This guide doesn't exist on the 3-2-stable branch...
I couldn't quite figure out where the guides were now to make a patch; so I thought to quickly document what I learnt. Thanks guys!
@drnic no worries, I'm just messing with you. Better to bring it up than to not!
Add upgrading note to 3.1 release notes.
Update 3.0 -> 3.1 session information.
