Improvements to Close desktop apps
We've recently launched updated versions to both the Windows and Mac OS X desktop Close applications.
Both the Mac and Windows apps were re-written for speed and stability, using an updated version of the same rendering engine that Chrome uses. They also included improvements that will result in better call quality and many causes of crashes were fixed.
The Windows app now also joins the Mac app in having spellcheck and in-app audio playback for voicemails and call recordings.
