-What: raw1394: requests of type RAW1394_REQ_ISO_SEND, RAW1394_REQ_ISO_LISTEN
-When: November 2005
-Why: Deprecated in favour of the new ioctl-based rawiso interface, which is
- more efficient. You should really be using libraw1394 for raw1394
- access anyway.
-Who: Jody McIntyre <[email protected]>

What: Video4Linux API 1 ioctls and video_decoder.h from Video devices.
When: July 2006
Why: V4L1 AP1 was replaced by V4L2 API. during migration from 2.4 to 2.6
