As part of our commitment to enable you to easily build on Facebook Platform, today we are announcing a roadmap which includes a series of changes and improvements that will roll out over the next two quarters.
These updates are designed to simplify communication for users and developers, improve app discovery and engagement, and provide you with more comprehensive tools for building or expanding your business with Facebook.
Through these new APIs and tools, we are giving all developers building with Facebook and those in our largest application category — gaming — new ways to attract and engage users.
Those are some significant changes that they plan to roll out without much notice. Over the next one to two months they are going to break functionality across thousands of apps. This road map is the least they could have done.
