Previously, authentication helpers were long and tedious to type out: new_refinery_user_session_path_the_quest_for_a_longer_method_name_part_two. It is unnecessary for them to be this long. login_path will do just fine, because the engine is now isolated. There's three new helpers: login_*, logout_* and signup_*.
I don't know how you deal with deprecation of the old ones, so I've just gone ahead and changed them now.
Shorten all authentication routing helpers
@ugisozols how would you like to write deprecations for the old paths?
This pull request passes (merged f928ab1 into 80416c8).
No idea but we'll figure out something.
@ugisozols were you saying that you worked out deprecations?
Haven't figured it out ...
Can we merge this in master without deprecations and figure out 2.0.x deprecations later?
This can't merge anymore; I guess we changed something!
Merged - maybe we can deprecate but we can for sure blog + tweet + changelog it
Add note to changelog about #1719.
