NetBSD 10.1 is now available. Discover what's new: AMD Zen 5 support, RAID improvements, ZFS on Xen and key security patches.

---

The NetBSD Project has released **NetBSD 10.1**, the first maintenance update of the 10.x branch, officially launched on **December 16, 2024**. It consolidates the stable line that started with NetBSD 10.0 and ships hundreds of bug fixes, new device drivers and security improvements gathered during the development cycle.

## Key highlights

- **New x86 hardware support**: NetBSD 10.1 adds compatibility with **AMD Zen 5** CPUs, plus specific fixes for Ampere processors and improvements to x86 virtualization.
- **RAID improvements**: the RAIDframe subsystem now handles hot removal of components and offers a simpler command-line configuration, which makes storage administration easier.
- **More network and USB drivers**: support arrives for the Realtek E2600 Ethernet, TP-Link USB adapters and various serial devices, so compatibility with modern equipment widens.
- **Virtualization and ZFS**: **ZFS performance on Xen** has been tuned, and the random number generator now reseeds automatically when a virtual machine is cloned. That matters a lot in cloud environments.
- **Network interface protection**: `bridge(4)` adds an isolation feature similar to "protected-port", handy for segmenting network traffic.
- **Strengthened security**: the SSH daemon patches the **CVE-2024-6387** vulnerability, `libarchive` is updated to version 3.7.7, and Mozilla root certificates are refreshed.

NetBSD is a free, Unix-like operating system descended from the Berkeley BSD branch, famous for its motto "Of course it runs NetBSD". What sets it apart is **portability**: it runs on a huge variety of architectures, from x86 and ARM servers to embedded hardware and vintage machines. Its clean, well-documented design makes it a fine choice for systems developers, researchers, embedded environments and anyone who values stability and code consistency.

If you want a solid, maintained system, NetBSD 10.1 is the release we'd point you to. You can review all the technical details on its entry in our directory: [NetBSD](/en/netbsd).
