scheme: platform release train, major.minor (4.x)
current_version: '4.23'
cadence: roughly every 2-6 weeks
date_note: Release-note dates are published in mixed and ambiguous formats (both DD/MM/YYYY
  and MM/DD/YYYY appear across entries, and the ordering of 4.16 vs 4.17 is inconsistent
  with either reading). The `published_date` values below are recorded verbatim as
  the provider prints them; they have deliberately not been normalized to ISO.
scope_note: The release notes are product release notes covering the platform as a
  whole (UI, engine, connectors), not an API-only changelog. API-affecting entries
  are flagged with api_affecting below. Recent window only; the live page is the source
  of truth.
