Rollout

Roadmap
557184

Rollout dates are often only in the text. When Microsoft moves them, the change shows under "What changed".

Schedule dates changed in the text

Date phrases in schedule sentences differ between the versions this installation saw
  • Seen 28 May 2026 late April 2026 → late June 2026
  • Seen 24 Feb 2026 mid-March 2026, late March 2026 → early April 2026, mid-April 2026, late April 2026

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.
