A new release of the 9front project is available, within which, since 2011, the community has been developing a fork of the distributed operating system Plan 9, independent of Bell Labs. The project's code is distributed under the Lucent Public License, which is based on the IBM Public License but differs by not requiring the publication of source code for derivative works.
Of the features of 9front, the addition of additional protection mechanisms, the expansion of hardware support, the improvement of work in wireless networks, the addition of new file systems, the implementation of the sound subsystem and encoders / decoders of sound formats, USB support, the creation of the Mothra web browser, the replacement of the bootloader and the initialization system, the use disk encryption, Unicode support, real mode emulator, support for AMD64 architecture and 64-bit address space.
The new version provides support for full-fledged work on the MNT Reform laptop, including support for graphics, sound, Ethernet, USB, PCIe, trackball, SD card and NVMe. MNT Reform does not yet support built-in Wi-Fi, instead of which it is recommended to use an external wireless adapter. The system has new programs bar (displaying a panel, for example, to display a battery charge indicator, date and time), ktrans (performs input transliteration), riow (hotkey manager) and doom (DOOM game).
The main idea behind Plan 9 is to blur the distinction between local and remote resources. The system is a distributed environment based on three basic principles: all resources can be viewed as a hierarchical set of files; there is no difference in access to local and external resources; each process has its own mutable namespace. The 9P protocol is used to create a single distributed hierarchy of resource files.
