Google Inc. operating system release , based on the Linux kernel, upstart init system, ebuild/portage build tools, open components, and web browser . The user environment of Chrome OS is limited to the web browser, and instead of standard applications, web applications are used; nevertheless, Chrome OS a full-fledged multi-window interface, desktop, and taskbar. The Chrome OS 79 build is available for most of Chromebook. Enthusiasts have created unofficial builds for regular computers with x86, x86_64, and ARM processors. texts are under the open Apache 2.0 license.
changes in :
- The ability to control multimedia playback directly from the system's lock screen, without activating the session, has been implemented. This feature is available for YouTube, Music, Spotify, and some other applications.
- Settings have been updated to allow enabling or disabling acceleration support for the mouse.
- The capabilities related to the use of virtual desktops have been expanded. When opening a new link, it now always opens in the current virtual desktop, simplifying user workspace separation.
- A new overview mode has been introduced for tablets, allowing for easy scrolling of open windows on the touchscreen. This mode works well even on small screens. To split the screen, simply long-press on a window, after which the window can be moved to the left or right side.
- Application management in settings has been unified — a new App Management section has been introduced for changing app settings and permissions;
- In the Crostini subsystem, designed for running Linux applications, restrictions on network port numbers that can be used for launching network handlers in the Linux environment (e.g., for testing web applications) bound to the local network interface (localhost) have been removed. The upcoming Chrome OS 80 release is expected to transition the base Linux environment to Debian 10 components (currently using Debian 9) and allow USB device passthrough for use in the Linux environment.
- For locally connected printers, an advanced settings block has been added to the preview window, allowing changes to PPD attributes in CUPS such as stapling, perforation, tray selection, etc.
In one of the upcoming releases, printing through connections to external print servers is expected. - In the ARC++ environment (App Runtime for Chrome, a layer for running Android applications on Chrome OS), access to the Google Play directory is enabled by default. Previously, Google Play was disabled by default and could only operate in a mode offering a limited set of applications. This limitation has now been lifted, and Google Play is available for all corporate user accounts without the need for administrator privileges.
- the verified boot algorithm, which uses the dm-verity module for cryptographic verification of the root partition. Until now, the SHA1 algorithm was used to generate a hash for integrity assessment of the partition, which, despite earlier , the risk of collision is quite low in a branched hash generation structure made up of hashes from different data blocks. Nonetheless, it was decided to replace SHA-1 with a more reliable SHA256 algorithm. To avoid slowing down the boot process, as SHA256 requires more computational resources, numerous optimizations were conducted, enabling performance very close to that of booting with SHA-1.
