The OpenBSD project produces a free, multi-platform 4.4BSD-derived UNIX-like operating system. Emphasizing portability, standardization, coherency, correctness, proactive security and integrated cryptography. It comes with almost 9000 software package in its ports, including a custom X11 environment (Xenocara), desktop environments, web and multimedia applications, compilers and programming languages. It also harbours the OpenBSD-maintained software projects OpenSSH, LibreSSL, OpenIKED, OpenBGPD, OpenOSPFD, PacketFilter, OpenNTPD, OpenSMTPD, OpenCVS, pfsync, spamd, tmux, sndio; which are designed with portability to other BSD and Unix-like operating systems in mind. OpenBSD itself runs on over 40 different hardware platforms.

Removed hardware support: lofn(4), art(4), urio(4).
Generic network stack improvements:
The routing table is now used for most of the address lookup operations superseding the RB-tree and IPv4 address list.
The SipHash algorithm is now used for PCB hashing, trunk(4) loadbalancing, pf(4) and bridge(4).
Traffic destinated to link-local IPv6 addresses can now be seen with tcpdump(8).
A carp(4) now needs to be configured with an explicit carpdev parent interface.
The mbuf(9) layer has been made mpsafe.
Introduce mbuf_list and mbuf_queue structures and APIs.
Support changing the IPv6 input queue length via sysctl(1) and net.inet6.ip6.ifq.
The etc and xetc sets are now part of base and xbase and are not distributed separately anymore.
