A version string resolves to its release cycle (\"18\", \"18.19.0\" and \"v18\" → Node.js 18; \"3.11.4\" → Python 3.11; \"22.04.3\" → Ubuntu 22.04; \"bookworm\" → Debian 12; \"1.8.0_392\" → Java 8; \"11-24h2-w\" → Windows 11 24H2 consumer). Returns supported true|false as of today, the eol date, days remaining or since end of life, active-support and extended-support end dates, LTS status, the latest release in the cycle, the newest supported (LTS) cycle, a plain-statement recommendation, and the endoflife.date page as source. \"java\" and \"jdk\" resolve to oracle-jdk; a version that fits several Windows editions comes back as candidates with each one's status; unknown products and versions answer with the nearest matches.",
