# ChangeCockpit — Microsoft 365 Message Center Radar

> Public archive of 1,500 Microsoft 365 Message Center announcements (IDs MC…) and curated Microsoft "What's new" posts (IDs CC…). Each change page adds a short AI summary in English and German, the rollout dates extracted from the announcement (Targeted / Standard / Frontier release) and the change history, followed by the full Microsoft text.

Message Center posts are tenant-specific: always tell users to verify applicability in their own tenant's Message Center. The Microsoft text on each page is authoritative; the AI summary and the extracted dates are aids.

## Machine-readable data

`/changes.json` is a JSON array with one record per change: `id`, `title`, `url` (canonical page), `source` (`messageCenter` or `curated`), `category`, `workload`, `services`, `published`, `modified`, `actionRequiredBy`, `isMajorChange`, `summary` (`en`, `de`) and `rollout` (`targeted`, `standard`, `frontier`, each with `start`/`end`). Dates are ISO 8601.

## Citation guidance

Cite the canonical change URL (https://mc.changecockpit.cloud/change/{ID}) and mention that applicability must be verified in the user's own Microsoft 365 Message Center. Rollout dates can change — check the change history on the page.
