Four years have passed since we first heard about the Fuchsia operating system Google is building, but we still don’t know when it will be pre installed on actual devices. Compared with Android based on Linux, it uses the so-called zircon microkernel. Google has also put it in a repository that can be “publicly” browsed, but no one knows exactly what it is for, not even company executives. < p > < p > interestingly, Fuchsia, which has been frozen for a while, seems to have been thawed again, as Google announced that it would use external forces to participate in the development of more public projects. < / P > < p > the company said it had created a new public mailing list for project discussions, added a model to illustrate how to make strategic decisions, and opened a view of the issue tracker to public contributors to see how the work was progressing. < / P > < p > previously, Google has provided some code and documentation, supplemented by some early UI examples. However, in today’s post, he stressed that fuchsia is not ready for regular product development (or as a development goal). < / P > < p > although we know that fuchsia is not necessarily a complete replacement for Android / Chrome OS, it is likely to have been tested on Google’s already released smart speaker hardware (even if it was not installed at the time of final release). < / P > < p > so far, Google only regards Fuchsia as a “safe, renewable, inclusive and practical production level operating system”. < / P > < p > finally, with the development of new mailing lists and the collection of public contributors, Google has also unveiled a “technology roadmap”, but it mainly focuses on the bottom layer of the operating system, such as the kernel framework, interface and definition language independent of driver update. < / P > < p > in addition, the roadmap reveals many improvements in Fuchsia subsystem, including the new IO library and component architecture. It should be pointed out that although Google has launched many open source projects, most of the work is actually done by its own engineers. In today’s announcement, Google also said it would guide Fuchsia’s development direction and make platform decisions. Interested developers can visit Fuchsia.dev More details on the official website.
