 API changes, most recent first:
+2015-11-29 - xxxxxxx - lavc 57.16.101 - avcodec.h
+  Deprecate rtp_callback without replacement, i.e. it won't be possible to
+  get image slices before the full frame is encoded any more. The libavformat
+  rtpenc muxer can still be used for RFC-2190 packetization.
+
 2015-11-xx - xxxxxxx - lavc 57.16.0 - avcodec.h
   Add AV_PKT_DATA_FALLBACK_TRACK for making fallback associations between
   streams.
