  Roughly every two weeks. 30 dated releases published between 2025-10-03 and 2026-08-31, moving
  from weekly beta drops in late 2025 to a fortnightly minor cadence through 2026.

note: >-
  AAICO publishes a genuinely dated, itemised release-notes section on its developer hub, indexed
  in llms.txt, with every release reachable at its own URL and individual changes carrying stable
  IDs (e.g. v2.6-001). Releases are badged Minor/Major but no entry in the published window is
  marked breaking, and there is no separate API changelog — platform and API changes are mixed
  into one product stream, so an API consumer cannot filter for contract-affecting changes.
sections_per_release: [Digital Twin, Discover, Build, Run, Optimize]

  - Process-level metadata side drawer (objective, volume, duration, systems, pain points)
  - Minimap for large process canvases
  - Reworked Members page; org-unit tagging across the File Library
  - Builder: copy node as Markdown, copy every variable at once, dates that resolve at run time
  - OCR fixed on PDF inputs; input node accepts batches of 150+ files

gaps:
- No API-specific changelog; contract changes are not separable from product changes.
- No release is flagged breaking, and there is no migration-notes convention.
- No RSS/Atom feed or machine-readable changelog format is published.
