- 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)

New in SHOUTcast DNAS 2.4.2.167 (Nov 25, 2014)
- 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
New in SHOUTcast DNAS 2.4.1.165 (Nov 25, 2014)
- Fixed the DNAS not finding cacert.pem which breaks all DNAS-YP connectivity due to issues processing relative filepaths
New in SHOUTcast DNAS 2.4.1.164 (Nov 25, 2014)
- 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 (if people don't use this, then it will be dropped permanently)
- Other miscellaneous code changes, improvments and related documentation updates (including handling immediate segfaults on start-up)
New in SHOUTcast DNAS 2.4.0.147 (Sep 10, 2014)
- 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, improvements and related documentation updates
New in SHOUTcast DNAS 2.2.1.109 (Dec 5, 2013)
- Completed remaining v1.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 v1 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
New in SHOUTcast DNAS 2.0.0.29 (May 29, 2012)
- Changed SHOUTcast 2 client header to show the DNAS's actual version instead of just 'SHOUTcast 2.0'
- Fixed SHOUTcast 2 compatible clients only allowed to connect as a SHOUTcast 1 client (build 27 / 28 specific)
- Fixed more config files being shown than allowed on non-Windows versions when no configuration file specified
New in SHOUTcast DNAS 1.9.6 (Jun 20, 2006)
- fixed "/content/" exploit #2
- html in source info
