[ Josselin Mouette ]
* Set the team as primary maintainer. Closes: #523538.

[ Luca Bruno ]
* New upstream release. Closes: #526798.
  + Features a MP2 audio profile. Closes: #502059.
* debian/control.in:
  - Build-Depends:
    + Add libcanberra-gtk-dev 0.4.
    + Add libunique-dev.
    + Bump libglib2.0-dev to 2.18.2.
* debian/patches/01_vumeter_nodisplay.patch:
  - Remove, vu-meter isn't being built by default since 2.23.

[ Josselin Mouette ]
* Update build-dependencies, include libpulse.
* Explicitly enable the gst mixer.
* Install the autostart file in /usr/share/gnome/autostart.
* Install OMF and sound files.
* 10_applet_tryexec.patch: new patch. Only run 
  gnome-volume-control-applet when pulseaudio is installed.
* Split install targets for gnome-volume-control and gst-mixer. 
  Install selectively what comes from each of them.
* Install both gnome-volume-control.pulse and 
  gnome-volume-control.gstreamer. The real gnome-volume-control is now  
  a wrapper script.
* Depend on x11-utils for the wrapper script to work.
* Suggest pulseaudio.
