In Windows 11, support for a new scroll bar style was added, while for the macOS platform, system font loading was improved, which in some situations made it possible to open and switch to a new tab faster.
In the version for the platform Android, the selection in the history of visits to recently opened sites is implemented, as well as an improved display of images for recently added bookmarks on the home page. On the Android 12 platform, the issue of pasting links from the clipboard has been resolved.
While for the part of the novelties for developers the following stand out:
- Added support for the @scroll-timeline CSS rule and the animation-timeline CSS property, which allow animation timelines in the AnimationTimeline API to be bound to content scroll progress rather than time in minutes or seconds.
- Changed the name of the color adjustment CSS property to print-color-adjust as required by the specification.
- CSS has support for cascading layers by default, defined with the @layer rule and imported with the @import CSS rule using the layer() function.
- Added the scrollbar-gutter CSS property to control how much screen space is reserved for the scrollbar.
