This is a VERY early version of the module and should not be used in production (at least not if you don't know what you are doing.) Please report any problems you may encounter in the issue queue!
Modularity: Now it's possible to use the core sign-in functionality without using the standard UI and widgets (useful for custom sign-in UI implementations).
Profile 2 and User fields are now supported in addition to the (deprecated) Profile core module.
Integration with the Rules module, providing "Linked account added (deleted)" events that can be used to invoke actions when a 3rd party identity is added or deleted.
Complete Engage user profile data mapping support (with an easy to use Engage data field browser).
