Facebook introduced the Facebook Developer Roadmap on October 28, 2009. This is what the description of the roadmap reads:
For the first time in this level of detail, we will provide a roadmap to help you anticipate future changes and opportunities. Like all roadmaps, it may shift slightly, but we will share insight into what is happening as these details are available. We’ll keep you posted about the progress of these changes and what they mean for you over the next two quarters.
For the month of November Facebook had 4 new features to be launched, and while most of them are now live, one of the most anticipated ones is nowhere to be seen. I’m talking about the new email sharing feature, which allows developers to gain access to the application’s users’ primary email address. This means that app developers can store real email addresses and contact their users directly. Currently applications can request permission to email users, but the emails get sent via the Facebook API and are not visible and cannot be stored.
Also, once this feature is live, the new notification methods will become active (after 30 days) and most likely this is when the new redesign will be activated.
