>which is going to be a bit hairy for people accustom to <= Rail 3.x finder syntax and ancient plugins that somehow manage to still work. Yeah, but that pain will come regardless. Better I think to wait until the dust settles on turbolinks et al and plugin authors update. You could always update first to 4.0.x (for mild to large values of x) or what have you before jumping over to 4.1. Point is, if you've got a large app it's not worth pushing back any deadlines. Someone's gotta do it! and much to love to the rails-core team, but being 3 months behind the release schedule still counts as "bleeding edge" in most of the rest of the software world ;).
