Up to 12 section headings from retained before/after evidence. The current source may have changed again.

Why this was flagged

The changed words, with a few words around them, matched these rule categories: dates and deadlines, supported platforms. These matches identify subjects to assess; they do not establish a policy change or applicability.

Observation time is not publication time, and a comparison does not establish an effective date. Full source bodies are not published; this page holds generated summaries, section headings and, as the page's license allows, Microsoft's changed wording. A documentation edit does not confirm feature availability in an environment.

Timeline

From the capture of 19 Oct 23:40 UTC

Relative periods

Counted from an event the source describes, such as installing an update; they are not calendar dates.

Requirements, exceptions and scope

Extracted automatically from Microsoft's wording. Confirm dates, conditions and whether they apply to you in the source before acting; a month or quarter is a window, not a day.

How this timeline changed

Changes between ChangeIntel's readings of the page, between commits of its source file where Microsoft publishes it, in Internet Archive copies of pages that keep no other history, and entries from Microsoft's own change log (dated as Microsoft dates them). Edits between readings that neither records are unknown.

Review priority. Extracted assertions require review · Publisher marks guidance tentative · Applicability or exceptions require review

0 date changes and 0 condition changes across 2 compared revisions. Suggested check interval: 6 hours.

Earlier unavailable versions and edits between checks are unknown. A missing statement requires review; it does not mean the policy was cancelled. Recovered historical statements are not original revision snapshots.

Compact evidence remains available after full document bodies expire. Earlier extractions can have different vocabulary or capture limitations.

Microsoft's edits

History on GitHub

Commits to the page's source in MicrosoftDocs/azure-management-docs, with Microsoft's own messages. Commit dates can be hours or days before Learn publishes the change. ChangeIntel keeps a copy of each diff, so an edit stays readable here if GitHub stops serving it. Read 19 Oct 23:40 UTC.
