Update History page missing May 12, 2026 Patch Tuesday release for Microsoft 365 Apps (Current Channel Version 2604, Build 19929.20164)

The "Update history for Microsoft 365 Apps (listed by date)" page at:

https://learn.microsoft.com/en-us/officeupdates/update-history-microsoft365-apps-by-date

is missing the May 12, 2026 Patch Tuesday security update entries in the Version History table.

Current state:

  • The "Supported Versions" table at the top correctly shows Current Channel Version 2604 (Build 19929.20136, May 5, 2026)
  • However, the "Version History" table below does NOT include the May 12, 2026 security update row with Build 19929.20164

Expected:

  • Version History table should include a row for May 12, 2026 showing:
    • Current Channel: Version 2604 (Build 19929.20164)
    • Monthly Enterprise Channel: Version 2603 (Build 19822.20182)
    • Other channels as applicable

Additionally, the related security updates page:

https://learn.microsoft.com/en-us/officeupdates/microsoft365-apps-security-updates

should also reflect the May 12 CVE details for this release.

This delay impacts downstream automation that depends on the Version History table to track Office 365 security update builds. Could you please update these pages at the earliest?

Thank you.

    The May 12, 2026 Patch Tuesday security update entry for Microsoft 365 Apps (Current Channel Version 2604, Build 19929.20164) is not present in the Version History table for 2026 in the provided context. The latest Current Channel entry shown there is Version 2604 (Build 19929.20136) with a release date of May 5, 2026, and there is no May 12, 2026 row yet. The security updates page content for that date and build is also not present in the context.

    Because these pages are owned and maintained by Microsoft’s documentation team, the only supported action is to wait for the official content to be published or updated. Once the May 12, 2026 release is processed, it will appear in:

    • The “Supported Versions” table when that build becomes the latest supported Current Channel build.
    • The “Version History” table for 2026 with the corresponding release date and build.
    • The Microsoft 365 Apps security updates page with the associated CVE details.

    For automation that depends on these tables, the safest approach is to design workflows to tolerate a delay between Patch Tuesday and the time when the documentation tables are updated, and to re-poll the pages periodically until the new row appears.
