Summary
- Microsoft has released a new update for Microsoft 365 Apps on the Current Channel.
- The update will be delivered automatically to clients that use the Office CDN for updates.
- If your organization manages Microsoft 365 Apps updates directly, you can download the release and deploy it yourself.
- Review the linked Current Channel release notes for version details and any app-specific changes.
Microsoft released fresh updates for Current Channel clients starting late September 2026. Organisations relying on the Content Delivery Network will receive these changes automatically. Administrators managing local software deployment should review the release notes and prepare to distribute the new version according to internal testing schedules.
Administrator impact: Review the release documentation and prepare local deployment packages if you do not use automatic updates.
End user impact: Users will receive the latest client features and security improvements through the standard update process.
Score rationale: This is a standard routine software release requiring local deployment action only if automated update channels are not used.
