What happened
NetBSD 11.0 ships with 64-bit RISC-V support, improved Linux system-call compatibility, POSIX.1-2024 and C23 compliance, and a dedicated MICROVM kernel that boots in roughly 10 milliseconds on 2020-era x86 processors. The release also adds preliminary Qualcomm Snapdragon X Elite (Arm64) support and a virt68k port for running Motorola 68000 NetBSD under QEMU.
Why it matters
The MICROVM kernel's ~10ms boot time is the one detail worth noting if you're evaluating lightweight VM isolation for short-lived workloads or serverless-style execution, though NetBSD's minimalism and lack of out-of-box tooling mean most teams will stick with Linux or a mainstream hypervisor. RISC-V support matters only if you're already experimenting with RISC-V hardware or emulation.
Discussion angle
Whether a 10ms-booting MICROVM kernel changes the calculus for lightweight VM-based isolation versus containers, and why almost no one in the room will actually switch to NetBSD to get it.
