  • add scored feature candidates and exact build metadata for the current RC 1 branch head
  • add the reader-facing RC 1 release-notes index

Build provenance

  • Base: v11.0.0-preview.7.26381.103
  • Head: origin/release/11.0.1xx-rc1
  • Runtime: 11.0.0-rc.1.26427.112

The RC 1 branch is still moving, so these artifacts will be refreshed against the final tag before publication.
