- Update to version 4.0:
* There can now be only one pavucontrol window open at a time.
Trying to start pavucontrol for a second time brings the first
window to foreground.
* Added a "Show volume meters" checkbox to the Configuration tab.
Disabling the volume meters reduces CPU use.
* Improve the use of space (remove useless margins and paddings).
* Use a more appropriate icon for the channel lock button.
* Better channel label layout, prevents volume sliders from getting
unaligned.
* Maximum latency offset increased from 2 to 5 seconds to
accommodate AirPlay devices that often have higher latency than
2 seconds (this is not that useful on newer PulseAudio versions,
though, because the latency is reported much more accurately
than before).
* New --version command line option.
* Dropped support for Gtk+ 2.
* Bumped the minimum supported libpulse version to 5.0.
* Improved compatibility with newer Glade versions.
* New translations: Chinese (Taiwan), Croatian, Korean, Norwegian
Nynorsk, Lithuanian, Valencian.
* Updated translations: Finnish, French, German, Italian,
Japanese, Polish, Swedish.
