▶ [minor] #5995
Generic Worker: Adds task.payload.feature.loopbackAudio for loopback audio device support on Linux.
The snd-aloop kernel module must be installed on the host system for this feature to work, although it does not need to be loaded. Generic Worker loads the module with modprobe and generates the virtual audio device with a snd-aloop command. Under the multiuser engine, it also manages file ownership of the device with chown to ensure that only tasks with suitable scopes have read/write access to the virtual device.
For tasks that enable the feature, the virtual audio device will be found at /dev/snd. Devices inside that directory will take the form /dev/snd/controlC<DEVICE_NUMBER>, /dev/snd/pcmC<DEVICE_NUMBER>D0c, /dev/snd/pcmC<DEVICE_NUMBER>D0p, /dev/snd/pcmC<DEVICE_NUMBER>D1c, and /dev/snd/pcmC<DEVICE_NUMBER>D1p, where <DEVICE_NUMBER> is an integer between 0 and 31, inclusive. The Generic Worker config setting loopbackAudioDeviceNumber may be used to change the device number in case the default value (16) conflicts with another audio device on the worker. Future releases of Generic Worker may provide the capability of having more than one virtual audio device; currently only one virtual audio device is supported.
▶ [patch] #6481
Allow git SSH urls in metadata.source.
▶ [patch] #6476
Generic Worker now checks the Index to see if there is a new version of an Indexed Artifact available. If there isn't, it is fine to use its cached copy, but if there is, it updates its cache.
▶ [patch]
Generic Worker: If a Docker Worker payload is received, the resulting, d2g-translated Generic Worker payload will be logged out to the user.
▶ [patch] #6438
dependencies are no longer removed from the task definition when you Edit or Retrigger a task.

▶ [minor] #6269
Generic Worker now provides configuration property maxTaskRunTime as an upper bound for task payload property maxRunTime. Tasks with maxRunTime exceeding this value will be resolved as exception/malformed-payload.
