 ### v3.6.7
 - Fix: remove regression caused by optional chaining and nullish coalescing in check for `window.CSS` check for aspect-ratio (fixes #2174)
 ### v3.6.6
 - Improvements to how aspect ratio is handled. Use `aspect-ratio` CSS property instead of the legacy method (still used as fallback). Also automatically determined aspect ratios are rounded to the nearast standard ratio. This fixes issues with the YouTube embeds showing a 1-2px black bar.
 - Hide the YouTube poster image container when paused so that the controls underneath can be used.
 ### v3.6.5
 - Migrate color formatting to colorette (thanks @jorgebucaran)
 - Fix: issue with IE detection
 - Fix: missing styles for embeds
 - Fix: regression regarding poster image
 - Add all required props to vimeo iframe allow attribute - fixes #2151 (thanks @didrip)
 ### v3.6.4
 - Remove unnecessary calc from media query (thanks @naomiaz)
 - Enhance types (thanks @lunika)
 - Fix: Object.values for the providers must be used (thanks @syteknet-core)
 - Fix: Improve support inside iframes (thanks @ajgagnon)
 - Added --plyr-video-background for having control over the background of a video with alpha channel (webm) or a poster image with alpha channel (thanks @nepomuc)
 - Fix issue with not entering iosfullscreen of vimeo videos with playsinline=true (thanks @lordon and @Frosch)
 - fix: use new syntax for iframe allow attribute
 - chore: package updates
 - chore: add @babel/plugin-proposal-class-properties
 - fix: use bound arrow functions in classes
 ### v3.6.3
 - Fix volume when unmuting from volume 0 using YouTube (thanks @stephanefbouchard)
