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.

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.
