> Backbone and Knockout are continually maintained I don't know for Knockout but Backbone is a zombie. His creator basically says no to any new feature and has very little time to manage the project anyway. See the commit logs for this year ,they are merely "cosmetic". A lot of things could be fixed or added -- a better router(with states and sub states) , composite views , composite models that do not need verbose hand plumbing -- without even breaking backward compatibility , but there is no plan to add anything significant to the core. I Never tried CanJS though , It looks like an interesting alternative to Backbone.
