  0.5.2 (to be announced) "orthogonal interior"
  ---------------------------------------------
  
 -      - The new sync synchronizes playback between multiple clients.
 +The new sync filter, the AES_CTR128 stream cipher and the overhauled
 +network code are the highlights of this release. It also includes a
 +fair number of smaller fixes and improvements not mentioned here.
 +
 +      - The new sync filter synchronizes playback between multiple
 +        clients.
 +      - Connections between para_server and para_client are now
 +        encrypted by means of AES rather than RC4 if both sides
 +        support it. RC4 is still available as a fallback. This
 +        feature is fully transparent, i.e. no command line options
 +        are necessary, and a client linked against openssl can
 +        speak with a server linked against libgcrypt and vice versa.
        - Major cleanup of the networking subsystem.
 +      - Improvements to para_fade: the new set mode, multi-channel
 +        initial volumes, better error logging.
 +      - The man pages of para_audiod, para_filter, para_recv, and
 +        para_write contain the relevant options for receivers, filters,
 +        writers. This broke in 0.5.0.
++      - ogg/vorbis latency improvements.
 +      - Improved user manual.
        - Minor fixes to avoid clang warnings.
