Changes in Pannellum 2.2.1
--------------------------

New Features:

 - NPM support

Improvements:

 - Set `Accept` header to request images
 - Ensure `hfov` is a number
 - Better restriction on yaw range


Changes in Pannellum 2.2.0
--------------------------

New Features:

 - An API has been added instead of just a standalone viewer; the API should be
   considered experimental at this point and may be subject to change
 - The `PosePitchDegrees` and `PoseRollDegrees` XMP tags are now supported
   (used by the Ricoh Theta S)
 - Optional fade animation for transitioning between scenes using the
   `sceneFadeDuration` parameter

   for a specific period of time before stopping

   (`hotSpotDebug`)
 - Parameter to disable keyboard zooming (`keyboardZoom`)

Improvements:

 - Much better equirectangular video support using Video.js
 - High-DPI support
 - Unified configuration files; tour configuration files can now be used
   directly with the `config` parameter

   instead of a web server

   release; tour JSON configuration files can be used with the `config`
   parameter
