Read from date phrases in Microsoft's text, not from notice metadata. A changed phrase can be a moved rollout, a new milestone or just rewording; "What changed" below shows which.

What the notice says

Microsoft’s text, with source markup removed
Updated June 11, 2025: We have updated the timeline below. Thank you for your patience. If an organizer updates an event that you have been invited to, you will now see Event Updated in the email and the updated location if applicable. This message is associated with Microsoft 365 Roadmap ID 491018 When this will happen: General Availability (Worldwide): We will begin rolling out on late June 2025 (previously early June) and expect to complete by late July 2025. General Availability (GCC): We will begin rolling out on late June 2025 (previously early June) and expect to complete by late July 2025. General Availability (GCC High): We will begin rolling out on late June 2025 (previously early June) and expect to complete by late July 2025. General Availability (DoD): We will begin rolling out on late June 2025 (previously early June) and expect to complete by late July 2025. How this will affect your organization: Users will now understand that their event is being updated when receiving event related emails, when applicable. If the user has already RSVP’d to an event, and the organizer makes an update to the title, subject, or location, the email update will show “Event Updated” and the updated location (if applicable). Previously, the email update would show the event time and not explain that the event has been updated. This feature will not affect events that the user has not responded to and will not affect event updates where the organizer changes the time.  New Experience: Old Experience: If an organizer updates the title, location, or description of an event that the user has already responded to, the email update will only display the event time.  What you need to do to prepare: This rollout will happen automatically with no admin action required. You may want to notify your users about this change and update any relevant documentation as appropriate.
