# FactClock

> A living reference of current software versions, supported release lines and end-of-life dates for 460+ products — each with an as-of timestamp, a primary source, and a change history. Regenerated daily; Markdown and JSON on every page. More sections to come.

Every fact page exists in three forms: HTML (`/<section>/<slug>/`), Markdown (`/<section>/<slug>.md`) and JSON (`/api/<section>/<slug>.json`). Each states the current value, an as-of date, the primary source URL, whether the product is still supported, and a change history. Per-page Atom feeds at `/<section>/<slug>/feed.xml`. Regenerated daily. Page text CC BY 4.0.
