description: >-
  Structured capture of Rerun's dated release changelog. Rerun uses semantic
  versioning across a single lockstep-versioned monorepo (SDKs, viewer, CLI all
  share a version). Minor releases (0.x.0) routinely carry breaking changes;
  patch releases (0.x.y) are bug fixes. Recent window only; the CHANGELOG.md is
  the source of truth.
