 +0.6.3 (to be announced) "generalized activity"
 +----------------------------------------------
 +
 +- The ff command now accepts a negative argument to instruct the
 +  virtual streaming system to jump backwards in the current audio
 +  stream. The old syntax (e.g., "ff 30-") is still supported but it
 +  is deprecated and no longer documented. The compatibility code is
 +  sheduled for removal after 0.7.0.
 +- para_afh: New option: --preserve to reset the modification time to
 +  the value of the original file after meta data modification.
 +- Overhaul of the compress filter code. The refined algorithm should
 +  reduce clipping. The meaning of --aggressiveness has changed, see the
 +  updated and extended documentation of the compress filter for details.
 +- Cleanup of the audio format handler code.
 +- We now build the tree using the .ONESHELL feature of GNU make,
 +  which results in a significant speedup.
 +- Two robustness fixes for FreeBSD.
 +- para_client now supports RFC4716 private keys as generated with
 +  ssh-keygen -m RFC4716. In fact, this key format has been made the
 +  default, and the former PEM keys will be depreciated at some point.
 +- The ogg audio format handlers learned to detect holes and now report
 +  the correct duration also if ogg pages are missing in the file. This
 +  affects ogg/vorbis ogg/speex and ogg/opus.
 +- Robustness improvements for para_mixer.
 +- A fix for an old bug that could cause the server to crash or report
 +  garbage in its status output.
++- New para_play option: --end-of-playlist
