OpenBSD 7.3 released

Calgary and elsewhere, 2023-04-10:
The OpenBSD project today announced the release and general availability of its latest stable version, OpenBSD 7.3.

Eagerly anticipated by users, engineers, enthusiasts and industry pundits all over the world, this release contains a number of improvements over earlier versions, including but not limited to

• Improved hardware support, including new arm64 variants and numerous network and graphics driver updates
• Improved general and network performance due to steadily improving multi-core support
• More flexible network configuration,
  now supporting lladdr-based config
  [See earlier report.]
• retguard for amd64 system calls
  [See earlier report.]
• Enhanced memory and process security [See earlier report]
• Relinking of network exposed daemons at boot time
  [See earlier report.]
• execute-only (xonly)
  [See earlier report.]

• Support for disk encryption in the installer
  [See earlier report.]
• X11 Mesa shader cache enabled.
• More aggressive randomisation of the stack location for all 64-bit architectures except alpha
  [See earlier report.]

You may notice that the list of OpenBSD Innovations has grown a bit too, while the detailed changelog offers more detail.

All reasonably modern architectures had install sets and complete binary packages available on the mirrors at the time of the announcements.

Some slower (historic or just weird) architectures are still building but OpenBSD still supports 14 architectures.

While you are waiting for your downloads, installs or upgrades to complete (or even before starting either), please remember to visit the donations page and/or buy OpenBSD swag to support the project financially.

And finally, this release is the first since OpenBSD 7.0 to feature a release song. The Wizard and the Fish is the new obligatory addition to your hacking playlist.
