Apple changes for IT admins

Vendor-announced Apple retirements, end-of-support dates, and admin-impact changes — normalized, dated, and verified against official sources.

The IT Admin Change Calendar summarizes vendor-announced changes from official public sources, normalized for administrators. Every entry links to its first-party source and shows when it was last verified. It is informational — it cannot confirm how a change affects your specific tenant, and it is not a complete mirror of every vendor release note.
