  • Swipe to navigate: swipe right or left to navigate backwards and forwards.
  • Support for accessing Physical Web content from the Today view.
  • Stability improvements and bug fixes.

Chrome 44 implements the following new features and updates:

  • Cache.add() - add() takes a RequestInfo object, fetches it and adds the response object into this Cache object.
  • Computed Property Names (ES6) - Allows expression for property names in object literals and class literals.
  • Document.scrollingElement - Simple API to indicate whether 'body' or 'documentElement' is used for scrolling. Used to ease transition to spec-compliant scrolling behavior.
  • and ServiceWorkerRegistration.getNotifications() - Support for the attribute, which allows authors to attach some (immutable) data to a persistent Web. Notification they are displaying. Support for the static ServiceWorkerRegistration.getNotifications() method for getting all existing persistent notifications created by the current origin.
  • Request.context - Request.context contains the context of the Request, such as "fetch", "image", "script", "frame", etc.
  • WebAudio: ChannelMergerNode Static Routing - This is to change the behavior of ChannelMergerNode when the input changes dynamically. There have been critical issues with the previous. implementation. To address these issues, a new proposal for the ChannelMergerNode was made. The proposal effectively makes the channel order in the merger node static after the instantiation.
  • WebAudio: Disallow setting AudioBufferSourceNode.buffer more than once - Setting AudioBufferSourceNode.buffer again after it has already been set to a non-null buffer is no longer allowed and will generate an exception. This feature was deprecated and is now being removed.
  • beforeinstallprompt event for web/native app install banners.
