OSMF – Release 1.5 is now available
This release includes lots of bug fixes plus support for FMS 4.0 Multicast and FMS 3.5.3 Stream Reconnect. The stream reconnect logic will try to reconnect you to the FMS server if you switch from wired to wireless, for example. If the reconnect happens before the buffer empties, you get a seemless experience. If the buffer does empty, it will try for 2 minutes to reconnect and if successful, it will start right where it left off. Both of these new features require Flash Player 10.1.
