How this list is chosen
Changes from 20 Jan 2025 – 26 Jan 2025 UTC and dates due up to 25 Feb 2025. Dates are the source's own, or labelled as the day ChangeIntel observed a change; never inferred effective dates.
Ranked by kind: exploited vulnerabilities, then up to 3 dates, open known issues, and other notable changes, with at most one entry per feed. Service incidents are on the status board; security baseline downloads, first captures of a document, and metadata-only documentation checks are left out. This is a view of retained evidence, not a reconstruction of everything known at the time.
The briefing is selective. Browse every dated change, review upcoming dates or check the period's coverage.
