How this list is chosen

Changes from 27 Apr 2026 – 3 May 2026 UTC and dates due up to 2 Jun 2026. 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 7 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.
