NetBSD 11.1, released November 2, 2026, is the first point release of the NetBSD 11 stable branch. Its main purpose is to deliver security fixes and resolve bugs quickly, rather than introduce a major set of new features. Existing users can upgrade by booting installation media and selecting Upgrade; those updating by other means should install the kernel and modules first, reboot, and then update the userland.

The fixes span a wide range of supported hardware, including repaired boot, stability, and processor issues on Alpha, ARM, MIPS, Atari, and Sun systems. Kernel and driver work addresses a potentially denial-of-service-causing IPv6 packet-parsing flaw, a virtual-memory race, snapshot problems, RAID reconstruction, SAS controllers, and USB Wi-Fi hotplug panics. Build improvements cover modern compilers, parallel debug builds, and cross-compilation from Apple Silicon Macs. Updated third-party software includes OpenSSH 10.6, Xorg 21.1.25, and Unbound 1.26.1, alongside security fixes in Brotli and libXfont2 and refreshed root certificates. The release provides binaries for dozens of architectures, from amd64 and aarch64 to RISC-V and many older workstation, embedded, and console platforms; ia64 is included but is not fully supported. NetBSD remains free and openly licensed, with source and signed distribution hashes available.
