Summary

With WebGPU support enabled by default in Safari 26 (shipped with macOS 26 Tahoe and iOS 26) a bunch of WebGPU features were enabled. All the features marked in this PR with "version_added" : "26" were already available in previous Safari versions with the WebGPU flag enabled, and are now enabled by default.

Both core-features-and-limits and texture-formats-tier1 are enabled at least in Safari 26.2. I don't have access to a machine with 26.1 or 26.0 and I haven't found when they were added.

LGTM overall, except:

  • One feature was added in 26, not 26.2.
  • All Safari iOS support statements should be changed to "mirror", cf. failing lint.
