What is the newest Anthropic Claude version tracked here?
Claude Haiku 5.5, released 2026-10-07. This is the newest release included here, not necessarily the newest vendor release. Unresolved releases may be omitted while their dates or support status are checked. See the linked vendor source for current releases.
Where do these Anthropic Claude dates come from?
From the vendor sources linked at the top of this page (vendor lifecycle page) and the source entry. Vendors can revise dates, so confirm there before you schedule a migration.
Note: "Not announced" means no confirmed date is shown here; check the linked vendor source. "Ended (no date published)" means the source marks it ended without a date. Dates are compared as calendar days in your own time zone. A published end date counts as the last day of support.
Data: endoflife.date (MIT license), feed retrieved 2026-11-04. Retrieval does not mean every displayed value was verified that day. Some values are retained from earlier reviews, and unresolved releases or dates may be omitted. Confirm with the linked vendor source before a purchase or migration decision.
