Ubuntu introduces architecture variants
Michael Hudson-Doyle, a member of Ubuntu's Foundations team, has announced the introduction of an "architecture variant" for Ubuntu 25.10:
By making changes to dpkg, apt and Launchpad, we are able to build multiple versions of a package, each for a different level of the x86-64 architecture, meaning we can have packages that specifically target x86-64-v3, for example.
As a result, we're very excited to share that in Ubuntu 25.10, some packages are available, on an opt-in basis, in their optimized form for the more modern x86-64-v3 architecture level.
See the announcement for details on opting in to x86-64-v3 packages.
