- Update from version 5.5.2 toi 5.6
- No change in rootfile
- Changelog
5.6
Things You Can’t Ignore
    Shairport Sync and NQPTP have both been updated to Shared Memory Interface 11
	(smi11). You should update and install NQPTP first, then update and install
	Shairport Sync. Then, restart NQPTP and Shairport Sync, in that order.
Security Updates
    The default ALAC decoder is now from the FFmpeg library. The Hammerton decoder is
	no longer the default ALAC decoder for Classic AirPlay builds; it remains an
	option but is strongly deprecated for security reasons.
    A number of memory allocation and out-of-bounds issues have been identified and
	dealt with. Thanks to Akhil Koul, Yegor Yefremov, Dirk Mueller, Haavar
	Valeur, Tristan, Filipe and memoriaru.
Remote Control for AirPlay 2.
	We are thrilled to announce that remote control of AirPlay 2 players is now
		available. Shairport Sync has had remote control facilities for
		Classic AirPlay players for some time -- for example, you could
		control play, pause, skip and change volume via Shairport Sync's
		MPRIS, D-Bus or MQTT interfaces, but this only worked only on
		Classic AirPlay (aka AirPlay 1) players, and "Advanced" controls were
		only available for iTunes or the macOS Music app.
	Most of these remote control facilities are now available on AirPlay 2
		players using the same Shairport Sync commands and properties. (This
		is still a work in progress: the RemoteControl.Available and
		AdvancedRemoteControl.Available properties remain false in AirPlay 2
		operation even though the facilities are available.)
Enhanced Metadata for Airplay 2
	AirPlay 2 provides much more metadata than classic AirPlay. This is now
		provided in the metadata pipe under the copl (for COmmand PList)
		type, and on the D-Bus interface alongside existing metadata. (The
		sample metadata pipe reader shairport-sysc-metadata-reader has also
		been updated and a few bugs fixed.)
Improved D-Bus and MPRIS interfaces
	    The MPRIS interface has been brought closer to the true MPRIS standard:
		Volume, Loop Status and Shuffle are now settable properties as
		specified in the standard, whereas up to now they were read-only
		properties.
	    The D-Bus interface has likewise been enhanced: Volume, Loop Status and
		Shuffle are now settable properties. Most of the RemoteControl and
		AdvancedRemoteControl suite of commands and properties are available
		on AirPlay 2 connections.
	    The D-Bus interface has two new properties: NowPlayingInformation and
		CommandInformation. Both of these are essentially raw feeds of
		metadata coming from AirPlay 2. The only exception is that raw
		picture data is removed from the NowPlayingInformation and is
		replaced by a local file reference to the same data.
	    The MPRIS Position property has been fully implemented, for Classic and
		AirPlay 2 operation.
	    MPRIS and D-Bus interfaces now check parameters and report errors before
		accepting a command or setting a property.
Full Support for macOS
    A new native CoreAudio backend is now available for use with macOS. This provides
	full audio synchronisation on Mac. NQPTP has also been updated for macOS,
	enabling AirPlay 2 as well as Classic AirPlay service on Mac. Thanks to
	Filipe for their work on this.
Support for Multiple Instances of Shairport Sync
	This refers to the possibility of running multiple copies of Shairport Sync
	 on the same hardware, which was not thought possible. However, thanks to the
	 work of Haavar Valeur and Jay Love, it now seems feasible. Please refer to
	 the Running Multiple Instances guide for further details.
PipeWire Volume Control
	    Shairport Sync can optionally control its own ("stream") PipeWire volume
		or the overall ("sink") PipeWire volume of the entire system. Use the
		new mixer_type setting in the pipewire section of the configuration
		file. If no mixer_type is specified, Shairport Sync's own mixer is
		used and no PipeWire volume settings are affected. Thanks to gearhead.
	    pipewire = {
	      ...
	      mixer_type = "sink"; // pipewire mixer_type either "sink" or "stream"
	    }
Other Enhancements
    Improved handling of clock mastership changes that occur when a player containing
	a new grandmaster is added to or removed from the set of output devices.
    Support for Mbed TLS 4, thanks to Yegor Yefremov.
    Support for uncompressed Linear 16-bit signed PCM (CD-quality) streams, thanks
	to Filipe.
    Very specialised configuration file settings have been added to force AirPlay 2
	reception to 44,100 frames per second only and to enable or disable 48K ALAC
	Lossless reception.
    Richer plist-encoded metadata is now used by default for AirPlay 2.
    TIFF album artwork is recognised and file-tagged correctly.
Bug fixes
    Fixed a bug causing AirPlay 2 sessions to stop unexpectedly due to periodic
	connections from other players. Thanks to mjardemalm for the detective work!
    Fixed a memory allocation bug in the pairing code. Thanks to Akhil Koul.
    Stopped a crash when metadata support is built in but metadata is turned off in
	the configuration file.
    Fixed a bug whereby setting a specific RTSP port for AirPlay 2 was ignored.
	Thanks to Haavar Valeur.
    Fixed a bug in the construction of Bonjour strings.
    Fixed an invalid memory free and a leak of the interface list in tinysvcmdns.
	Thanks to Yegor Yefremov. Note that tinysvcmdns remains deprecated for
	security reasons.
    Fixed a potential read overflow, thanks to Dirk Mueller.
    Fixed latency offset calculations by deferring them until the input rate is
	known. Thanks to prhodey.
Docker Enhancements
    Preserve user-supplied PULSE_SERVER and PULSE_COOKIE, thanks to Joel Town Road.
    Add ENABLE_NQPTP to opt out of starting NQPTP in Docker, thanks to Haavar Valeur.
Other
    The list of licenses in LICENSES has been updated.
    Software tests have been updated.
    The file structure of the repository is changing.
    Various Dependabot updates to the CI system have been made.
