OpenBSD 6.3 Released

Contributed by rueda on from the cranking-the-handle dept.

April 2, 2018: The OpenBSD project has announced the availability of the newest release, OpenBSD 6.3:

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.

The release page contains a more complete list of changes, and the upgrade page gives recommendations on how to upgrade to the new release.

    First of all, all my thanks to all the programmers!

    OpenBSD 6.3 is, so far, a great release, and I did note the OS was checking automatically for possible syspatch on each reboot. The updates to OpenSSH and LibreSSL are also greatly appreciated.

    One (innocent) question is: are all the relases going to go "live" in advance of the official release date?

    In any case, kudos to everyone involved, and, to the OpenBSD Foundation: take my money, please!

      We intend to use the May 1 and Nov 1 dates as the latest dates for a release. For internal scheduling reasons, we will often be ahead of those and will release when we are ready.

      So while it may be often/always true that we release early, we aren't guaranteeing it.

          You are both right! :-D

          But, again, I am not complaining: OpenBSD is definitely one of the most polished OS out there.

          Thank you all, donation has been sent to the usual suspects.
