  pulseaudio (1:8.0-0ubuntu3.11) xenial; urgency=medium

  * Backport the snap policy module to make access to audio recording
    conditional on plugging the "pulseaudio" or "audio-record" interfaces
    (LP: #1781428):
    - 0450-modules-add-snappy-policy-module.patch: rewrite to query
      snapd for the client's plugged interfaces.
    - 0451-enable-snap-policy-module.patch: enable the module in the
      default configuration.
    - Build depend on libsnapd-glib-dev.
  * Backport libjson-c dependency removal from Pulse Audio 10. This is
    required by the snap policy module due to a symbol name clash with
    libjson-glib.
    - 0805-remove-libjson-c-dependency.patch: new file.
