NEWS: September 23rd 2026. Upgrades to SPARC m35, with gcc10, now available. This is a synthetic release with new packages atop m34 as the underlying OS - see the SPARC Release Notes. The latest SPARC ISO available for download remains at m34.

Important: 32-bit hardware support now completely removed.
