Added clearing the cached stats / playlist responses to the 'clearcache' admin method
Added a generic html5 audio player to the bottom of the stream summary and admin summary pages as a quick way to check what the stream is playing (mp3 streams only and relies on the browser default implementation)
Added caching of the public stats and other commonly accessed pages and resources (1 sec) and playlist (5 sec) responses from the server to improve response times under heavy loads
Added 'startrelays' and 'kicksources' admin modes for batch starting configured relays and batch stopping of all connected sources
Adding a lot of extra parameter validation based on reproduceable crashes and input validation failures
Added support for additional genres on the appropriate DNAS pages, api responses and listener connections (how to access this will follow later)
Added basic support on the Linux build to get some form of crash report with it creating a file like /tmp/sc_serv_segfault_<pid>.log (where <pid> is the process id)
Added better debug output for tracking transitions into and out of the advert plays as well as the number of successful plays
Added a debug column when admetricsdebug=1 is set for better tracking of advert issues in addition to the tooltip shown in the connected column
Added 'referer' and 'x-forwarded-for' values to the listener stats api responses (user request)
Added option on the server admin summary page for manually checking for new versions of the DNAS

Changed the ordering of the http requests and checks done to speed up commonly accessed pages (in-addition to caching changes)
Changed some of the curl instances to only be created when actually needed and to not be done for private stream instances
Changed the advert title display on the song history page to make it clearer what is sent to the clients to make it clearer when an advert title trigger was received and what the listener is sent once its processed
Changed the error messages when core authhash values are missing in the YP responses instead of showing a generic 400 error message
Changed 'streampath' handling to filter some inappropriate values seen including self-referencing addresses

Changed some common listener response strings to be initialised once instead of every time
Changed title updates to filter out duplicate title updates where applicable
Changed all url / ip config value checking to be done consistently and applied to all applicable cases
Changed the Windows builds timer resolution to a preferred method which will not affect the system wide timer resolution (that was a bad thing to be doing)
Changed the station name link to shoutcast.com to use the now preferred method
Changed the 'songhistory' default from 10 to 20 to provide an average of an hour's song history
Changed the 'metainterval ' default from 8192 to 16384 to better match other broadcasting platforms
Changed the display of the log / config files on the admin pages to just show the filename and not a complete / partial filepath with the full path as the tool tip for the items
Changed to show the relay icon for Icecast connections on the listener list so all known relays are clearly visible
Changed to cache the user-agent of the valid client connection to save re-querying them in other parts of the DNAS

Changed how some parts of the server are built to prevent data being modified when it should not
Changed w3c log archive name to better distinguish from normal log archive naming

2.4.2 Build 167 / 168
Fixed issues with not finding cacert.pem in the same location as the DNAS program file which was preventing YP connectivity working (2.4.1 build 164 specific)
Fixed broken relative config file handling not working correctly with init scripts and 3rd party control panels (2.4.1 build 165 specific)
Changed some of the log and admin page output to better show the actual filepath being used for log and configuration files (helpful for determining path loading issues)
Changed handling incase the cacert.pem file cannot be found to be more forgiving for the time being (futher changes will follow in later builds)
Removed 'Error writing to console' log messages when screenlog=1 (default) and the shell the DNAS was started in is closed whilst the DNAS is still running e.g. due to OS defined timeouts - always use screenlog=0 if running the DNAS and you do not need it sending log output to the console
2.4.1 Build 164 / 165
Added features relating to the 'DNAS+ for CDN' streaming solution
Added ability to preserve the peak listener numbers for a stream between DNAS sessions e.g. when updating the DNAS (subject to conditions) - this requires the stream being publically listed and will be disabled if found to be abused!
Added experimental support to allow streams using 1.x source clients to be able to provide stream branding artwork via 'artworkfile' and 'streamartworkfile' configuration options (this enables basic stream branding artwork support for legacy 1.x based streams subject to client support [as below] - for 2.x based streams, the source should already have the ability to provide the stream branding and now playing artwork)
Added ability to provide artwork to 1.x clients via the legacy in-stream metadata system when provided from a 2.x source or when using the experimental support mentioned above (subject to clients supporting this feature - see the wiki for more information)
Added 'email' configuration option so hosts can provide a generic contact address (which is used during authhash creation / updates if not manually specified)
Changed YP connections to use HTTPS - this means a valid cacert.pem must be present in the same folder as the DNAS program file otherwise the DNAS cannot list streams
Changed file permission defaults on non-Windows builds to be more consistent between the different APIs internally used for files created by the DNAS
Changed the update notifications to provide extra information where possible about the update
Fixed YP connectivity issues introduced during the change over to using libcurl in the 2.2.2 / 2.4 releases e.g. randomly stops updating or prevents the DNAS from being able to close correctly or does not correctly handle cases when the YP is not contactable
Fixed handling of custom streampaths with parameters (starting with /; or ;) always providing stream #1 (using /stream/x/ did not experience this issue)
Fixed rare issue leading to high CPU usage when using a single core non-Windows system
Fixed rare crash when accessing some of the admin pages on non-Windows builds
Fixed some IP formatting issues on the admin pages
Removed remaining ICY support so all client connections are now via standard HTTP requets as 2.4 did (ICY was a HTTP-like protocol)
Removed the 'disableicy' configuration option for controlling this support (not needed due to the prior change)
Updated to support newer YP requirements for authhash handling and listing modes as well as related tweaks to the authhash management pages
Updated to OpenSSL v1.0.1j
Return of the BSD 8.x build
Other miscellaneous code changes, improvments and related documentation updates (including handling immediate segfaults on start-up)
2.4.0 Build 147
Added support for the Radionomy advert and metrics platforms so you can earn money from overlaying some adverts on the stream and / or leveraging the online broadcasting tools from Radionomy (this is an opt-in feature and requires a Radionomy account - it does not prevent you using the DNAS like before)
Added 'publicip' to be used to specify a DNS / IP value to use for what the YP will see as your server address when 'destip' is used for binding against a non-public value e.g. anything in the loopback address range (see documentation for usage)
Added 'alternateports' which can be used to allow for client only connections on port(s) other than 'portbase' e.g. to deal with firewalls blocking client access on some networks
Added 'disableicy' to the options handled by the configuration reload action
Added 'rotateinterval' to allow for changing the time between automatic log rotations (default is 24 hours) and can be set to 0 to disable log rotation completely
Added basic command-line help into the DNAS itself (use /? or --help) which is based on the OS version being used without the need to consult the main documentation
Added better handling of the intro and backup files to ensure they match the stream format and will now reject files which do not match the bitrate
Changed 'disableicy=1' handling (default behaviour since 2.2.2) to allow 1.x clients which explicitly request in-stream metadata to still receive it e.g. VLC and foobar2000
Fixed crash when rotating the log and w3c files (this was mainly seen under Centova Cast installs) and some other log file handling refinements
Fixed authhash issues specific to the 2.2.2 release (mainly seen as a 462 error code when trying to use the management actions)
Fixed handling of unrecognised loopback addresses causing incorrect addresses in some of the DNAS responses e.g. the listen.* methods
Fixed MP3 intro files breaking stream playback (such as causing stuttering or just not playing anything else) when transitioning to the actual audio stream e.g. most Flash based players (this is an issue going all the way back to the v1.x DNAS!)
Fixed MP3 streams not starting on a full audio frame (this should improve client compatibility, more so with Flash based players)
Fixed the 'Block User Agent' column on the stream admin page not showing the correct action (it could be shown in the 'Reserve Client' in some cases)
Fixed repeated admin login prompt when trying to manage an authhash in some cases (mainly if having per-stream admin passwords)
Removed specific handling for the deprecated AOL shoutcast.com site / embeddable Flash player (that specific player is no longer officially supported hence removing support for it)
Other miscellaneous code changes, improvments and related documentation updates
2.2.2 Build 123
The first Radionomy provided SHOUTcast DNAS release after the sale of SHOUTcast (and Winamp) in January 2014
This is primarily a maintenance release to resolve issues and broadcaster requests with the 2.2.x DNAS since the last build provided under AOL ownership
Added 'pidfile' option to control the creation of the file containing the process id of the DNAS (this defaults to creating 'sc_serv_<portbase>.pid if not specified in the same folder as the DNAS)
Added ability to block user agents from connecting to the streams on a global and per-stream basis if required (via admin pages and admin api methods)
Added 'agentfile', 'streamagentfile' and 'saveagentlistonexit' configuration options to allow for where and how the sc_serv.agent file is stored (which is used for holding the blocked user agents)
Added 'blockemptyuseragent' configuration option to allow for preventing client connections without a user agent from connecting (note: some valid clients e.g. some hardware devices may not provide a user agent and enabling this may incorrectly block legitimate client connections)
Added 'Reload Banned List(s)' option to the server admin page to complement the 'Reload Reserved List(s)' option
Changed network handling on non-Windows builds to try to resolve the random crashes with large listener numbers and scale better (e.g. going over ~330 concurrent listeners)
Changed to use libcurl instead of a custom library for all YP requests to help resolve the YP connection reliability issues some users have seen with most of the 2.x releases
Changed 'disableicy' default from '0' to '1' so we now by default provide HTTP instead of ICY headers - this resolves all known HTML5 audio playback access issues
Changed the frequency and formatting of some of the log output
Changed 'unique' to also apply to the 'portbase' config option
Changed log file creation to use sc_serv_<pid>.log (where <pid> is the process id of the DNAS) if the default / fallback 'sc_serv.log' cannot be created e.g. due to file permissions creating / accessing an existing copy of the file (mainly affects non-Windows builds)
Changed 'maxuser' default from 32 to 512 listeners (you will need to ensure the OS can support this e.g. adjusting ulimit -n on non-Windows installs)
Changed 'relayreconnecttime' default from 30 to 5 seconds (based on usage feedback)
Changed 'adaptivebuffersize' default from 5 to 10 seconds (based on usage feedback)
Changed GCC version used to build the Linux / Raspberry Pi versions (now using GCC 4.7.2 instead of GCC 4.4.6 / 4.6.3 respectively)
Changed title update handling in respect to issues related to CVE-2014-4166 (which we were not informed about before it was disclosed!)
Fixed stream access issues (always providing stream #1) if streampath=/stream is set and providing multiple streams from the same DNAS
Fixed formatting error in the JSON version of the listener details (XML version was not affected)
Fixed some file handle leaks with log file handling (mainly happened when compressing older log files on rotation)
Fixed a number of YP error handling issues (mainly found from changing over to use libcurl) e.g. stuck on 'Processing...' when an error was logged
Fixed the 'city' value of the authhash not being correctly re-loaded when viewing the authhash
Other miscellaneous code changes, improvments and related documentation updates
Completed remaining 1.x compatibility improvements (specifically relating to YP availability issues so clients are now only blocked from connecting if there is no source connected)
Added experimental 'streamportlegacy' option to allow for supporting more than one direct legacy 1.x source connection to the server (see documentation for usage / limitations)
Changed Windows service install / uninstall messages when UAC elevation / admin access is required to undertake the action
Fixed issues due to a bug in the handling of the 'useicy' option which is now deprecated and replaced by the 'disableicy' option (see documentation for usage)
Fixed reported issues with the 'Source Login Details' page (mainly showing mode availability incorrectly)
Fixed missing 'UID' value for client disconnects in the main log output
Fixed some clients being incorrectly shown as 'HTML5' client types when they were not on the admin pages
Fixed compile issues preventing the BSD build from being built for the prior release
Other miscellaneous code changes, improvments and related documentation updates
Added a 'setup' mode which allows basic configuration of the server when run without a configuration file (see documentation for usage)
Added a 'builder' mode which allows for the configuration builder to be run within the server (broadcasting is disabled in this mode)
Added automatic authhash generation when a stream source is connected on a public stream and an authhash was not already present (can be disabled using autoauthhash=0)
Added /statistics which consolidates all of the /stats?sid=# results for all known and active streams
Added 'flashpolicyserverport' allowing the DNAS to serve up the Flash policy file (as per 'flashpolicyfile') on port 843 or a custom port (as well as on 'portbase')
Added serving of 'shoutcast.swf' for custom flash players to be handled in the same domain as the server (see documentation for usage)
Added listen.xspf and listen.qtl to the /listen* playlist options available (so now pls, m3u, asx, qtl and xspf are available on a stream)
Added 'portlegacy' to allow changing or disabling the port legacy 1.x sources connect on (see documentation for usage)
Added 'publicport' to allow changing the port reported to the YP servers and any clients using the /listen.* playlists where 'portbase' is not the port externally seen
Added option on 'Server Summary' page (accessed from admin.cgi?sid=0) to allow for manually setting the stream authhash e.g. if needed for a relay
Added 'Stream DJ' (if known) on the stream admin pages as well as <DJ/> in all statistics for getting the current DJ of the connected source (more formal specification than fiddling the IRC / AIM / ICQ values as used with 1.x DNAS setups)
Added 'streammaxbitrate' and 'maxbitrate' options for per-stream or global limiting of the source bitrate allowed for a connection
Added 'streambackupurl' option for per-stream fallback if the original source (direct or via a relay) fails to keep the stream alive (see documentation for usage)
Added server bandwidth usage reporting for the server administrator via the admin.cgi?mode=bandwidth action (see documentation for usage)
Added JSON and JSON-P responses to the /stats?sid=# and /statistics responses by appending &json=1 for JSON and appending &callback=<function> for JSON-P
Added XML, JSON and JSON-P support to the /played response as well as to support &pass to allow song history access to the XML, JSON and JSON-P responses even when public display of them is disabled
Added admin.cgi?mode=viewjson as a JSON and JSON-P equivalent of admin.cgi?mode=viewxml (see documentation for usage)
Added ability to kick all connected clients on a stream via the stream admin summary page in addition to the existing single client kicking
Added 'redirecturl', 'streamredirecturl' and 'streamhidestats' options for per-stream or global redirection / blocking of publically accessible pages when 'hidestats' or the new 'streamhidestats' options are enabled
Added SIGUSR1 and SIGUSR2 support in non-Windows builds for reloading the configuration file from the console (see documentation for usage)
Added SIGWINCH support in non-Windows builds for reloading the Reserved IP file(s) from the console (see documentation for usage)
Added support for GZIP (RFC 1952) encoding of appropriate page and data responses if supported by the requesting connection and will provide a bandwidth saving
Added a 'View Source Login Details' page to the server summary page to make it easier to get the login details required for all appropriate stream configurations
Added sp=<streampath> support to all web methods which support sid=<streamid> to be able to access a page by streampath instead of streamid - streamid is still the preferred method (see documentation for usage)
Added 'admin.cgi?mode=viewlog&viewlog=save' method to allow for downloading the server log output as a GZIP compressed archive (useful for checking the log output remotely or for support issues)
Added 'streammovedurl' option for per-stream redirection of permanently stopped or moved streams from the server
Added archiving of log, w3c and streamw3c files when rotating these files would cause them to be deleted (which happens when there are usually five rotated copies already)
Added 'logrotates' and 'logbackup' options to provide finer control over the rotation (default of 5 files) and backup (default off) of the log files during rotations
Added icy=http parameter detection on 1.x client connections to return a HTTP instead of a ICY header response type e.g. server:port/?icy=http
Added 'url' parameter to the 'updinfo' action to replicate 1.x DNAS functionality which had not been re-implemented in the 2.x DNAS
Added 'dj' parameter to the 'updinfo' action to allow for scripted updating of the 'DJ' reported for a stream (useful for legacy source software)
Added 'ypstatus' method for the server administrator via the admin.cgi?mode=ypstatus action (see documentation for usage)
Added reporting of the stationid for public listings on the server and stream administrator pages
Added 'streamuptime' to the /stats and /statistic responses to aid in monitoring of the length of source connections to the server
Added /streamart?sid=# and /playingart?sid=# methods as a public version of the verions viewable via 'admin.cgi?mode=art&sid=#'
Added back /7(.html) support due to issues in getting legacy reporting tools updated to support the recommended 'stats' methods
Added admin.cgi?mode=history as an admin page equivalent of played.html?sid=# so stream administrators can easily see the played history of the stream
Added 'useicy' option to control if the DNAS will provide ICY (default) or HTTP (HTML5 compatible) headers for client connections
Improved YP interaction when the IP address of the DNAS changes whilst it is still broadcasting (requires YP update for this to work fully)
Improved handling of source relay connections especially via the server's admin pages e.g. a pending source relay connection can be aborted
Improved handling with large client numbers to reduce CPU usage as well as not crashing when exhausting the imposed maximum file descriptors (e.g. ulimit -n)
Changed 'streampath' to default to / for streamid=1 to improve compatibility (/stream/<sid>/ is still default on all other streams)
Changed config file handling to automatically use 'sc_serv.ini' or 'sc_serv.conf' if present if no config file is specified (better replicates 1.x DNAS behaviour)
Changed relayconnectretries to accept zero (relayconnectretries=0) to keep trying to reconnect to the relay source and changed the default to 0 from 3
Changed reporting of the YP connection state on the admin pages to make it clearer if the authhash is invalid or empty
Changed the 'Stream Configurations' xml response to fill <STREAMAUTHHASH/> with EMPTY or INVALID on error as applicable
Changed YP2 connection attempts to not be made if the authhash is determined to be invalid or empty
Changed 'hidestats' to allow for more control over the pages which are able to be disabled (see documentation for usage)
Changed 'updinfo' to not need 'type=xml' as it now auto-detects how to process the title information received
Changed 'configrewrite' to accept 'configrewrite=2' so now 'configrewrite=1' generates minimal configurations (only saves values not at the default) and 'configrewrite=2' outputs all configuration options (like 'configrewrite=1' used to do)
Changed YP2 handling to show the stream number, outputting of detailed error messages (where provided) and not output /yp/resp/updatefreq errors
Changed handling of the SHOUTcast site player client connections to not send in-stream metadata to workaround issues with title changes
Changed song history and current song titles shown in any reports to use the pre-formatted title from the source if available (does not change titles in clients)
Changed handling of introfile to attempt to strip any tags from the raw file to improve client compatibility
Changed client listener reports (via the stream administrator page and xml reports) to now be sorted oldest to newest
Changed w3c log handling to output header information to improve tool compatibility (replicates 1.x DNAS behaviour)
Changed handling of 'streamid' so if not specified then a stream configuration will be created if any appropriate stream* options are read on loading
Changed SHOUTcast 2 source logging to only output complete metadata and connection details when using uvox2sourcedebug=1 (instead of always as before)
Changed all /listen* playlist options to output the 'backupserver' provided by the YP where possible
Changed some of the server and stream admin page header links to better hide invalid options and to make navigation easier, etc
Changed the configuration reload option ('admin.cgi?mode=reload' on the 'Server Summary' page) to also update the debugging options and other options (see documentation for additions)
Changed Reserved IP handling to allow connections from 127.0.0.1 through even if not specified (allows access to admin pages)
Changed the Ban and Reserve IP administration actions to save changes (if enabled) at the time instead of only on exit
Changed YP2 stream registration to wait until the source has provided a title to allow the station listing to appear sooner (requires YP update for this to work fully)
Changed handling of authhash changes via the update option to update the current stream information without requiring the stream(s) to be restarted
Changed server summary page to count inactive relay configurations (if correctly specified) as available streams so it is possible to restart them easier
Changed the user agent (mainly for relay connections) to now be 'Ultravox/2.1 SHOUTcast Server x.x.x.x' (where x.x.x.x is the version and build numbers)
Changed the stream admin page to also report the type (1.x or 2.x) of the connected clients
Changed the current listener list on the admin summary page (admin.cgi?sid=#) to group client connections from the same IP address (make non-unique connections easier to find)
Changed all /listen.* handling to use the public IP of the DNAS as reported by the YP when publically listed (requires YP update for this to work fully)
Changed 'flashpolicyfile' handling to use an internal copy if a custom file is not specified (which has the benefit of specifying the actual ports used)
Changed console output to highlight errors in red, warnings in yellow and debug output in green to make them more obvious (cannot be disabled)
Changed the 'view logfile' administration pages to highlight errors, warnings and debug output to make them more obvious (colours can be changed via css)
Changed /stats?sid=# to support &pass to allow stats access even when public display of them is disabled
Changed Windows builds to only send warning and error messages to the event log in service mode or if a critical error happens on startup before file logging occurs
Changed autodumpsourcetime and streamautodumpsourcetime to be known as autodumptime and streamautodumptime respectively to better reflect the general usage of these options
Changed server summary page to display configured but non-running configurations along with active sources and inactive relay configurations
Changed 'yptimeout' default from 60 to 30 seconds
Changed 'Shoutcast Metadata Puller' handling to only return the title update (if enabled) instead of the audio data to help save bandwidth on popular listed streams
Changed GCC version used to build the Linux versions (now using GCC 4.4.6 instead of GCC 4.1.2 from CentOS 5.8)
Changed 'admin.cgi?sid=#&mode=kickdst' to support IP address(s) in addition to the existing unique client id(s) support
Removed Ultravox 2.0 (old Aol Radio) client and source support (reduces memory and cpu usage - amount depends on the setup used)
Removed 'yp2' configuration option and the ability to run the DNAS in YP1 mode
Fixed all reported issues with the authhash management system since it was first released for public use

Added 'faviconfile' and 'faviconmimetype' to allow for a local icon / image file to be served as the favicon.ico for the server webpages
Added 'robotstxtfile' to allow for a local robots.txt to be served as the robots.txt for the server
Added supporting features for in-stream artwork (related to March 2011 protocol changes) with online verions viewable via 'admin.cgi?mode=art&sid=#' for admins to check (see documentation for usage)
Added /stats?sid=# to allow easier access to the stream information (this mirrors admin.cgi?sid=#mode=viewxml&page=1) and is the effective replacement of 7.html
Added 'hidestats' to allow disabling of the new /stats?sid=# mode (see documentation for usage)
Added 'admin.cgi?mode=rotate' and SIGHUP support to rotate 'logfile', 'w3clog' and 'streamw3clog' whilst sc_serv is running (see documentation for usage)
Added ability to restart a kicked relay source via the administration pages
Added 'relayconnectretries' to control how many times a relay attempts to reconnect to the specified source before it is failed
Added a 5 second refresh delay when 'admin.cgi?mode=reload' is used and results in changes to source connections / relays unlikely to be displayed immediately

Added UNIQUELISTENERS to admin.cgi?mode=viewxml to complement REPORTEDLISTENERS (as the server status pages display)
Added STREAMPATH to admin.cgi?mode=viewxml for pages 0, 1 and 6 to show the 'streampath' of the specified stream configuration otherwise will output /stream/<sid>/
Changed the ban action for connected clients on the administation pages to also kick the client connection used for the ban action
Changed accessing stream and root urls (i.e. http://ip:port or http://ip:port/stream/1) in a browser to show the html pages (index.html) instead of providing the stream (replicates 1.x DNAS behaviour)
Changed the /listen* handling to improve auto-filling of the server IP in the generated playlist files
Changed the /listen* handling to attempt to provide a title much like the YP generated playlist files instead of just an address
Changed the delimiter in file paths read from the configuration file to be converted to the correct format for the OS being used
Changed the admin.cgi?mode=viewxml action to return a slimmer xml response compared to prior builds (to save more bandwidth)
Changed the rotate action to reset the 1 day delay until the next automatic rotation if a rotate is manually run
Changed how the SHOUTcast Directory metadata puller / tester is handled in client statistics to no longer skew listener totals
Changed how the version of the DNAS is reported to make it more like the 1.x DNAS as well as fixing it not being reported in some error response
Removed REPORTEDLISTENERS from admin.cgi?mode=viewxml for pages 0 and 1 as it duplicated the CURRENTLISTENERS entry
Removed POINTER from admin.cgi?mode=viewxml for page 3 as it duplicated the UID entry
Removed direct support for specifying 'relayport' and 'relayserver' (though if found then they are mapped to streamrelayurl against streamid=1 and will be removed if using configrewrite=1)
Fixed 'autodumpsourcetime' and 'streamautodumpsourcetime' not being applied correctly especially if either were set to 0
Fixed usage of 'streampath' in the listen playlists generated to ensure the formed playlist entry will work where possible for client connections
Fixed connection issues with YP directory listings when no 'streampath' is specifed (now ensures /stream/<sid>/ is set as the path so connections will be made against the correct stream)
Fixed some client connection issues when 'streampath' has been specifed (could lead to sid=1 being played even if the streampath_2 was attempted)
Fixed non-english title compatibility with 1.x sources i.e. titles with accented characters, was leading to title issues (also affected legacy DNAS builds)
Fixed some specific stream configuration issues with not all values being correctly mapped to the expected stream configuration
Fixed 'admin.cgi?mode=viewlog' to escape the log file contents correctly so appears correctly in the html output
Fixed issues with 'admin.cgi?mode=reload' where it could cause a lockup (non-Windows versions), caused incorrect removal of a configuration groups, source password changes not always applied, relays not being updated or started in all cases
Fixed logfile not being correctly set if no config file is passed but a selection is then made from the list shown
Fixed kicking and banning not working in some cases
Fixed issues handling invalid stream id values on source counnection attempts

Fixed listen.m3u not always providing a valid stream url especially when using 'streampath'
Fixed 'configrewrite' to no longer write some old / invalid configuration options when enabled
Other miscellaneous code changes, crash fixes, improvments and related documentation updates
Changed password handling to not allow 'password' to be the same as 'adminpassword' with relevant checks on the per-stream passwords
Changed Ultavox 2.0 Winamp clients (typically prior to v5.60x) to receive a 1.x SHOUTcast stream instead of an Ultravox 2 stream to resolve missing stream titles
Changed some of the reported details in the http headers used for SHOUTcast 2 (Ultravox 2.1) streams
Changed the stream admin page to also report the user agent of the connected clients
Fixed some more issues with password handling related to the changes in builds 17 and 18
Added per stream versions of the following configuration options (prefix with 'stream' to use them in addition to the master options e.g. streampassword): password, adminpassword, publicserver, allowrelay, allowpublicrelay, riponly, autodumpsourcetime, autodumpusers, listenertime, songhistory, uvoxcipherkey, introfile, backupfile, banfile, ripfile
Added 'logclients' configuration option to allow for client connections and disconnects to not be logged (default behaviour is to log these events)
Added summary administration page accessed via admin.cgi or admin.cgi?sid=0 instead of going to the default stream summary page (only works with 'adminpassword' access)
Added '&iponly=1' support to 'admin.cgi?mode=viewxml' so listener stats (in standard mode or when using &page=3) will only output the listener's IP address instead of all other information
Changed 'admin.cgi?mode=reload' to only be available via the new summary administration page instead of on each stream administration page
Changed the /currentsong and <songtitle> values to be a formatted title as 'artist - title' if the 2.x stream source metadata allows instead of just showing 'title'
Changed the /listen* actions to auto-fill the server IP in the generated playlist files if 'dstip / destip' is not set so the playlist is more likely to be valid
Changed the /home action to open the stream url in a new window / tab instead or replacing the current view of the admin pages
Changed the server to not load if appropriate passwords have not been specified (including per stream configurations) to improve security especially with per-stream password support
Changed the title produced for 1.x clients to be 'artist - title' instead of 'artist - album - title' to resolve some legacy client related issues
Changed some of the admin page text spacing and other misc html changes
Changed administration pages to not allow access to the 'tail logfile' and 'view logfile' pages when using 'streamadminpassword' to prevent information from other stream configuration groups being seen
Fixed the Ban and Reserve IP administration actions to not re-add an already banned or reserved IP (overlap of single vs subnets still happens)
Fixed stream configuration options not being applied correctly when using the plain name (without _X on the end) for streamid=1 configurations
Fixed /stream/sid client access not working correctly if an invalid station id (sid) was passed on the connection attempt
Fixed the root index.html page occassionally reporting streams as available when they are not

Fixed 'admin.cgi?sid=#&mode=updinfo' only updating the default stream configuration instead of the stream configuration required
Removed invalid link for the IRC stream entry on the administration pages
Updated Configuration Builder to latest version
Updated documentation to reflect new options and related errata
Improved handling of the mimetype reported by legacy mp3 sources to improve usage of 1.x sources (maps more mimetypes to audio/mpeg as applicable)
Added /nextsongs?sid=# to show the next coming songs in an xml form (if known) when using a compatible 2.x stream source
Added 'admincssfile' option to allow for using 1.x DNAS / SHOUTcast 2 / custom css styling of the index.html and the admin pages (check documentation for usage)
Changed 'admin.cgi?mode=reload&sid=#' to also update 'password' and 'requirestreamconfigs'
Changed 'configrewrite=1' to not output 'include' on exit
Fixed Windows version logfile path generation if none or an invalid configuration file is passed (relates to change of default logfile path to %temp%\sc_serv.log in previous build)
Fixed Windows service not running and being identified as sc_trans in the system event logs
Updated some of the example configurations to resolve issues with platform specific path handling
Added 'streammaxuser' to the stream configuration group options to allow for a per stream limit with 'maxuser' still ensuring a maximum client limit on the server
Added support for wildcards via the 'include' feature e.g. 'include=stream/*.conf' to allow for a specific file for each stream configuration on the server
Added a new 'admin.cgi?mode=reload&sid=#' mode to the administration support which will make the server reload its stream configurations by adding / removing / updating any streams on the fly where it can (unless '&force=1' is also passed) otherwise it will kick sources and clients as applicable
Added YP connection status on the 'Server Status' message on index.html and the admin page to make it easier to see if a YP connection on a public server exists
Added more information to the log generated to indicate if a YP connection has worked or not without having to enable debugging in the configuration file or completely cryptic messages
Added &page=5 additional param handling to the admin.cgi?mode=viewxml stats action to provide the currently held metadata of the playing song (amount of information depends on the source and what metadata it provides)
Added &page=6 additional param handling to the admin.cgi?mode=viewxml stats action to provide the currently known stream configurations (amount of information depends on the number of stream configurations specified)
Added Configuration Builder (see config_builder folder) as a graphical way of making working configuration files (in combination with forum user thinktink)
Now ships in linux 64-bit - is identified as 'posix(linux x64)' with the 32-bit version now identified as 'posix(linux x86)'
Changed YP2 connection failures to be reported more clearly instead of an obscure /yp/resp/updatefreq missing error or requiring 'yp2debug=1' to be enabled
Changed default location of the log file on Windows installs to %temp%\sc_serv.log instead of c:\sc_serv.log (resolves some issues on Windows Vista / 7 and write permissions)
Changed pvt_update(..) to not spam the logs when 'yp2debug=1' is enabled in the configuration file if a connection attempt to the YP2 fails
Changed http header checks to allow empty values from a 'key:value' pair to resolve some client connection issues
Changed the 'Server Status' message on the index.html and the admin pages to show 'There is no source connected or no stream is configured for stream #X' when the stream is not active or there is no source connected
Changed the reported configuration file on the index.html and the admin pages to be the base file loaded instead of the last included file if 'include' is used in the configuration files
Changed handling of 1.x sources to autofill the aim, irc and icq entries with N/A or 0 as appropriate if not set in what the source sends to the server e.g. Nicecast on Mac
Fixed an api dependency issue preventing this from running on Windows 2000
Fixed /nextsong?sid=# to show the unescaped version of the <soon/> metadata tag if received from the source
Fixed clients trying to connect via Ultravox 2.0 (e.g. Winamp 5.5x and older versions) not being able to connect or causing non-Windows versions of the server to terminate incorrectly
Fixed logging not working when passing certain invalid configuration files
Fixed admin.cgi?mode=resetxml not working - now will reset <peaklisteners> and <streamhits> fields to mimick 1.x DNAS handling
Disabled the <webdata/> block in the admin.cgi?mode=viewxml stats (as well as via the &page=2 additional param) for the time being
Disabled some of the admin.cgi?mode=viewxml stats entries not currently being filled in just to cut down on unnecessary bandwidth usage - better use the &page=# option to get specific sets of stats instead of all in one go to keep bandwidth usage down
Updated documentation based on user feedback and related changes, added sc_serv_simple.conf as an ultra simple configuration example, minor other issues & changes made
Added a disconnect message indicating the duration, number of bytes sent and agent of the connection being closed
Added a current and next song pages (/currentsong?sid=# and /nextsong?sid=#) along with <NEXTSONG> in the xml report for consistency
Added description for the Win32 service so it's clearer the service is ours
Accessing any admin / info pages with no stream id or the stream id is less than or equal to zero will show a summary of any available streams (if there are any)
Fully enabled SHOUTcast 2 (Ultravox 2.1) protocol support with server output (used with YP2=1 in config and a compatible connecting client)
Changed 'yp2' configuration setting default to 'on'

Minor log message changes to sort of standardise the message style
Fixed segfault issue when attempting to connect to YP2 (may have been an internal thing, not sure)
On Windows versions 'ctrl + break' is now handled as a valid quit command instead of just having the running instance closed
