The NetBSD Project is pleased to announce NetBSD 9.0, the seventeenth major release of the NetBSD operating system. This release brings significant improvements in terms of hardware support, quality assurance, security, along with new features and hundreds of bug fixes.
Support for the ARM architecture seems to be a major pillar of this new release.
The support for all the aarch64 boards via generic kernels is huge, and may make NetBSD an attractive proposition for embedded work. The absolute worst part of embedded Linux on ARM is every board needing its own special snowflake kernel and the OEMs charging out the nose for updated kernel packages.
