 ## Breaking Changes
 
+- `New-Guid` now generates Version 7 (time-sortable) UUIDs by default instead of Version 4
+  (random). The output format is unchanged. Scripts that depend on fully random GUIDs should use
+  `[guid]::NewGuid()` directly. ([#27033][27033])
 - Add `ValidateNotNullOrEmpty` attribute to the `-Property` of `Format-Table`, `Format-List`, and
   `Format-Custom` ([#26552][26552])
 - Use ArgumentException.ThrowIfNullOrEmpty for not-null-not-empty argument validation.
