Rollout

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 we saw
  • Seen 31 May 2024 late May 2024 → late June 2024
  • Seen 3 Apr 2024 early March 2024, mid-March 2024, late March 2024 → late April 2024, mid-May 2024, late May 2024

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.
