OpenBSD 6.4 Released

Contributed by rueda on from the When-I'm-6.4 dept.

The release of OpenBSD 6.4 has been announced:

We are pleased to announce the official release of OpenBSD 6.4.
This is our 45th release.  We remain proud of OpenBSD's record of more
than twenty years with only two remote holes in the default install.

Rather than reproducing the full list of new features here, we refer readers to the official OpenBSD 6.4 page.

Selected highlights include:

  • Support has been added for qcow2 images and external snapshots in vmm(4)/vmd(8).
  • "join" has been added for Wi-Fi networks.
  • Security enhancements include unveil(2), MAP_STACK, and RETGUARD. Meltdown/Spectre mitigations have been extended further, and SMT is disabled by default.
  • rad(8) has replaced rtadvd(8).
  • bgpd(8) has undergone numerous improvements, including the addition of support for BGP Origin Validation (RFC 6811).
  • smtpd.conf(5) uses a new, more flexible grammar.
  • For the first time, there are more than 10,000 (binary) packages (for amd64 and i386).

Those upgrading from version 6.3 should read the upgrade guide.

Readers are encouraged to show their appreciation in the conventional manner.

    Just upgraded my little VM from 6.3 to 6.4 flawlessly... As always.

    I will send a small donation to the OpenBSD Foundation.

    And a huge "thank you!" to all the programmers who have worked on this new release. I have been following OpenBSD for many years now, and I am always very very appreciative of all your hard work.
