  note: >-
    A rolling nightly build of master is republished as a GitHub release; assets are Brick.ttl,
    Brick+imports.ttl, Brick-only.ttl, Brick+extensions.ttl, imports.zip and extensions.zip.
cadence: >-
  The v1.2.0 release notes state Brick "will be targeting a 6 month cycle for 'minor' releases (e.g.
  Brick v1.x.y)". Observed practice since then has been looser — 1.4.0 (2024-04-15), 1.4.1
  (2024-08-23), 1.4.2 (2024-09-20), 1.4.3 (2025-03-20), 1.4.4 (2025-05-02), then a 13-month gap to
  the 1.5.0 release candidate.
release_notes_practice: >-
  Every release ships a machine-generated diff of ADDED and REMOVED ontology classes, produced by
  tools/compare_versions in the Brick repository, alongside a contributor credit list. RELEASE.md
  documents the process.
