Google has published this blog post about version 85.0.4183.83. According to this Google blog post, Chrome 85 is also available for Android. Chrome 85.0.4183.83 for the desktop contains a number of fixes and improvements. The Google-Blog contains this post about the organization of new tabs in Chrome 85.

  • For example, the tabs in the browser should now load 10 percent faster when switching. The new compiler optimization technique known as Profile Guided Optimization (PGO) makes this possible (see also this Google Blog post and this article at Bleeping Computer). 
  • Tab groups can now be grouped by topic or task for better visual differentiation. Tab groups can be folded in and out (see the animated image here). 
  • For tablets, the tabs should now be more touch-friendly.

In the article linked above, a number of further optimizations in the area of chrome tabs are listed and presented in animated images. Chrome 85 comes with extensive new features.

  • Among them are a QR Code generator, 
  • AVIF image support (the AV1 Image File Format (AVIF) compresses images using the AV1 codec and has proven to drastically reduce image sizes without significant loss of quality)
  • better protection against mixed content downloads, mixed content downloads are files that are delivered over an insecure HTTP connection when first launched from HTTPS sites With this release, Chrome displays a visual warning when downloading audio, video, image, and ext files (e.g., .png, .gif, .jpg, .mp4 files) with mixed content.
  • further secure cookies from the same website and application links for PWAs.

Bleeping Computer has published this article with some information about this. In the new Chrome 85 version, 20 vulnerabilities have been fixed by Google in the Chrome browser for the desktop.
