Software end-of-life date changes — which dates moved and what they were before

Canonical, always-current version: https://referencesource.org/software-eol-change-feed/ Machine-readable: https://referencesource.org/software-eol-change-feed/data.json — this mirror is a point-in-time copy.

Last verified: 2026-09-28
Stale after: 2026-10-12 (past this date, prefer the canonical copy — it re-verifies on a cadence this snapshot does not)
Records: 1273

A change log of software end-of-life and end-of-support dates across 462 products, built by diffing the endoflife.date API between snapshots: for each changed date, the product, release cycle, which field moved, the old value and the new value. Answers 'did the Python 3.9 EOL date change?', 'which Node.js support dates were extended this month?', and 'what EOL dates moved in July 2026?' — the question shape nobody publishes. endoflife.date tracks current state; endoflife.ai publishes a free monthly digest of what is critical now; neither publishes the before-and-after diff. New product additions are also captured. This is a parser case: the API returns structured JSON, no model supplies values.

Provenance — what every record carries

Every record carries source (the URL the value was read from) and source_quote (a verbatim quote from that page stating it). A value you cannot check against its page is indistinguishable from an invented one; these can all be checked. Each record is also individually addressable on the canonical site at its url.

Facts are not copyrightable; what this dataset takes from each source is a fact plus a short attributed quote linking back to the page that states it.
