In order to leverage the latest technologies and industry standards, future versions of Adobe Bridge CC (starting in Q2 2017) will support HTML 5 plug-ins based on the Adobe Common Extensibility Platform (CEP), and will end support for Flash/ActionScript based plug-ins.
Customers can continue to use older versions of Adobe Bridge (7.0 and older) for existing Flash/ActionScript-CEP plug-ins, but will not be able to take advantage of new features and performance enhancements in future versions of Adobe Bridge CC. Troubleshooting support for Flash/ActionScript plug-ins will not be offered following the next release of Adobe Bridge CC.
Customers interested in previewing Adobe Bridge support for HTML 5 can sign-up for early access via the Adobe Bridge pre-release program. Information on how to develop plug-ins for future versions of Adobe Bridge can be found here.
