After the major release of OpenBSD 6.8, here comes NetBSD 9.1, another popular and one of the oldest free and open source operating system from BSD family.

NetBSD 9.1 is the first point update for the NetBSD-9 release branch, bringing new features, bug fixes, enhancements, and stability improvements for ZFS and LFS.

What’s New In NetBSD 9.1?

Last month, we reported about the switch of the default X11 window manager from TWM to a new CTWM (Claude’s Tab Window Manager) in the NetBSD-current development branch. So now, it has landed in the stable NetBSD version 9.1 as well.

In addition, v9.1 also includes improvements to its X11 windowing system, LFS, and ZFS file system support.

If you use NetBSD on Lenovo ThinkPad laptops, then with NetBSD 9.1, you’ll experience better default input behaviour with clickpads and trackpoints.

Furthermore, v9.1 has added support for the Xen 4.13 hypervisor and updated NVMM hypervisor to bring improved emulation, performance, and stability.

For security purposes, version 9.1 has brought Parallelized disk encryption support with CGD cryptographic disk driver. You can even now use USB security keys in raw mode for several applications like Firefox.
