Recently Google announced, Through a blog post, the release of the new version of “Fuchsia OS 14” and in this latest update for the Google Nest Hub and Nest Hub Max, Fuchsia OS 14 fixes Bluetooth related audio errors, improves compatibility with Matter and finally solves the detection of “false events during the night”.
For those who do not know about Fuchsia OS, you should know that This is an OS based on the Zircon microkernel, derived from LK developments. It uses dynamic libraries run in user space, loaded by the devhost process, and managed by the device manager.
La Fuchsia OS graphical interface is written in Dart with Flutter, and the project includes tools such as Peridot for creating user interfaces, Fargo as a package manager, libc as a standard library, Escher for rendering, and support for various languages such as C/C++, Dart, Rust and Go.
The system It has file systems like MinFS, MemFS, ThinFS (FAT in Go) and Blobfs, along with FVM partition manager. In application development, Scenic and Magma are used as a composite manager, as well as a Vulkan driver. The boot process includes appmgr, sysmgr, and basemgr to configure the initial environment, boot environment, and user environment, respectively.
