Some of the key features of OpenBSD 5.1 include:
- Support by default for Synaptics touch-pads through the xf86-input-synaptics X.Org Input driver.
- Intel Sandy Bridge graphics support (it appears to be back-ported to UMS right now rather than Intel KMS on OpenBSD).
- An Assembler implementation of the AES-GCM module for new Intel and AMD CPUs with AES support.
- Improved IPv6 support.
- General networking improvements.
- Small improvements to Linux compatibility on i386.
- OpenBSD amd64/i386/sparc64 now supports the root file-system within a softraid volume, but the kernel needs to be booted from a non-softraid partition.
- OpenSSH 6.0 brings many changes and new features.
- There's over 7,000 ports available with major performance and stability improvements in the package build process.
- Some of the package highlights for OpenBSD 5.1 include GNOME 3.2.1 (only with the fall-back desktop mode), KDE 3.5.10, Xfce 4.8.3, Mozilla Firefox 3.5/3.6/9.0, LibreOffice 3.4, Mono 2.10.6, and Chromium 16.
