feature differences from CVS

fast pre-buffering - burst a certain amount of data at connection time.
mp3 accepts artist and title separately on the url.
program invocation at stream start and end, per mount based.
on-demand relays, activated on first listener, disconnected when listeners 
falls to 0
initial implementation of multiple Ogg codec streaming, theora, vorbis and
speex. more work needed to start at theora key frame.

kh31
. fix for bug when adding clients from pending list.

kh30
. add make static for those who want it
. changed code on list processing for active and pending clients
. changed when format-specific client data gets freed up
. shuffle code around, OK response to source client only source_client_thread

. more re-sync work + various non-functional cleanups

kh29
. revert test harness code left from before which advertised private streams
  and cleanup unwanted messages
. more cleanups, more sync work with CVS
. source_t wasn't going after source client disconnection

kh28
. more re-sync work
. fixed a yp deadlock case for stuffed yp servers.

kh27
. fixed 2 possible deadlock cases
. fixed race wrt to alias lookup after HUP change
. reset ogg stream type to "Ogg Vorbis" even if it isn't, so that YP
  shows icons correctly.

kh26
. fixed YP related bugs, leaks + bad pointer access
. fixed rare segv case in format_mp3
. more cleanup work in source shutdown
. Changed how client http headers are sent back
. Implement on demand relay, enabled with <on-demand>1</on-demand> in <relay>

kh25

  - added Ogg multiplexing
  - added theora and speex streaming
  - URL updates removed from vorbis, due to multiple codec support, maybe added later.
. continue with more re-sync to CVS work
. fixed a few rare races that had shown up with the re-sync work.

kh24

. on-connect/disconnect scripts are started and not waited on.
. icy/ice headers cleanup
. initialise config correctly

kh22
. fix some rare lock races
. page samples fix on EOS flush, reset granulepos to 0 on new stream
. add /admin/streamlist.txt from beta3
. big update of the relay code, supports master relay now
. added yp-log-headers tag in <logging> to disable YP header logging, it
  can make for lots of noise in the logs

kh21
. only send a 200 OK for source connections that are from source clientts
  and not relays
. on failed source init, some setup was not cleared and the source count
  was not decremented

kh17
. cleanup some api bits

kh16
. made outgoing serial numbers unique, helps in fallback situations
. revert date field to where it was in access.log. That way it conforms
  to the common log format for analysers.
. changed interal api of the client write function so that handling of
  burst limits is better. Also allow the queue to be more format specific.

kh15
. Updated vorbis input to rebuild stream, forcing pages to contain around
  1 second worth of audio.

kh14
. use localtime_r when available
. compile time switch for enabling/disabling logging IP in access log
. handle source counts better.

  stated per mount as well as globally.

kh12
. terminate stream if inline metadata does not contain "StreamTitle"

. fixed up listclients, moveclients.
. re-implemented source fallbacks

kh5
. 2 lots of ;; caused compile problems on windows
. enable curl for YP access
. allow the format specific get buffer routine to return
  NULL for retry, needs to set running to 0 now

    Support listening on multiple sockets.

2003-03-08
    Support for shoutcast source protocol added.

2003-03-08
    Started implementing generic admin interface. Supports (so far): 
    - dynamic configuration of mount fallbacks
        /admin/fallbacks?mount=/mount&fallback=/fallback
    - setting of mp3 metadata
        /admin/metadata?mount=/mount&mode=updinfo&song=New%20Title

        /admin/rawstats
    - listing all connected clients on a mountpoint: 
        /admin/listclients?mount=/mountname

2003-03-05
    Implemented the ability to reread the config file on SIGHUP. For now, this
    does not affect configuration for currently running sources (only new
    sources and global parameters like max-listeners)

2003-03-02 
    More features:	 
    -- per mountpoint listener maxima   
    -- static configuration of mountpoint fallbacks   
    -- stream dumping (write incoming stream to disk)

2003-02-27
    Fix log buffering on win32 - previously, logs were never flushed, so they
    only got output every few tens or hundreds of lines.

2003-02-27
	Support new icy-audio-info header, to communicate various parameters to
    clients and yp servers, including sample rate, quality, channels, bitrate

2003-02-25
    Full support for relaying mp3 metadata (if turned on in config file)

2003-02-25
    Allow configuration of maximum client queue length (in bytes)

2003-02-14
    Finished full IPv6 support. 

2003-02-12
	Allow configuring local mountpoint seperately from remote mountpoint for
    relays

2003-02-12
	Per mountpoint usernames and passwords (for sources)

2003-02-11
	Now that it's been officially assigned, use application/ogg instead of
	application/x-ogg

2003-02-07
    Allow relaying of mp3 streams from icecast 1.x and shoutcast

2003-02-07
    Added ability to configure individual relays (rather than just all streams
    from a single server).

2003-02-03
    Added support for YP directory services listings
	are only used by the yp listing routines

2003-02-03
    Support command line parameter -b to run in the background (not supported
    on win32)

2002-12-31 
    Implement configurable mountpoint fallbacks (on source exit, clients are
    transferred to another mountpoint automatically, without disconnecting
    them)

2002-12-31
    Implemented full mp3 metadata support.

(older stuff is missing from here)
