Watching for changes since 26 Sep 2026. Revisions Microsoft made before then were not observed, which does not mean there were none.
Nothing about Microsoft 365 Copilot yet in: open known issues, versions.
A change belongs to Microsoft 365 Copilot when it comes from a source about the product or one of its names (Microsoft 365 Copilot, Microsoft Copilot (Microsoft 365), Copilot Chat), when a roadmap entry, Windows release, or known issue lists it, or when an MSRC CVE, CISA entry, or lifecycle date names it. Another product's notes and community posts that only mention Microsoft 365 Copilot are listed under "Also mentioned in" and are not counted as its changes. Sources marked quiet are about Microsoft 365 Copilot alone and have had nothing new for 30 days; check the source before reading silence as "no change".
