Note: "Not announced" means the vendor has not published a date. "Ended (no date published)" means the source marks it ended without a date. Dates are compared as calendar days in UTC, so a date can flip up to a day earlier or later than your local calendar.

Data: endoflife.date (MIT license), snapshot 2026-09-23. Dates come from each vendor's published lifecycle. Always confirm with the vendor link before a purchase or migration decision.
