We are pleased to announce the official release of OpenBSD 6.3. This is our 44th release. We remain proud of OpenBSD's record of more than twenty years with only two remote holes in the default install.
Notable changes include:
- SMP is supported on arm64 platforms.
- amd64 Intel CPU microcode is loaded on boot.
- Many improvements have been made in vmm/vmd.
- Several parts of the network stack now run without KERNEL_LOCK().
- slaacd now generates stable IPv6 stateless autoconfiguration addresses (RFC 7217), and supports any prefix size as required by RFC 4862.
- Multiple security improvements have been made, including Meltdown/Spectre (variant 2) mitigations.
- pledge() has been modified to support "execpromises" (as the second argument).
- Filesystem handling in suspend/hibernate has been improved.
As usual, there are updated versions of OpenSMTPD, OpenSSH, and LibreSSL.
