Among the changes to find with Chrome 86 include:
- Easier/better file-system access with the Native File System API where users can grant web apps access to a given file/folder for reads and writes. This can be useful for video/image editors, code editors, office suites, and more within the web browser.
- A back-forward cache has been added to allow instant navigation on previously-visited pages.
- New APIs to support cross-screen window placement for better multi-screen experiences on the web.
- WebCodecs as a low-level codec API for game streaming, transcoding, and similar uses.
- The WebHID API for supporting human interface devices directly from the browser that may not otherwise be supported by the underlying operating system.
