Tue Mar 5 2019:
[11]Version 4.0 released. Changes:
* 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.
* New translations: Chinese (Taiwan), Croatian, Korean, Norwegian
Nynorsk, Lithuanian, Valencian.
* Updated translations: Finnish, French, German, Italian, Japanese,
Polish, Swedish.
* Dropped support for Gtk+ 2.
* Bumped the minimum supported libpulse version to 5.0.
* Improved compatibility with newer Glade versions.
