## What it is
The Java Version Almanac is a reference website and content repository documenting the history and future of Java releases, features, APIs, and JDK specifications. It is built with Hugo and published at javaalmanac.io under a CC BY-SA 4.0 license.

## Use cases
- look up which Java version introduced a feature
- check JDK release dates and EOL status
- compare Java APIs across versions
- find details about a specific JEP
- check which Java versions are LTS
- research the history of the Java language

## When to choose
- you need a quick, authoritative reference on Java version history and features
- you want to compare language, VM, or API changes across JDK releases

## When to avoid
- you need a runnable library or tool rather than reference content
- you need official or exhaustive specification documents instead of curated summaries

## Facets
- artifact type: learning-resource
- maturity: active
- function: documentation
- domain: programming-languages, documentation, tutorials
- platform: -
- tags: java, openjdk, reference-site, jep, static-site, hugo, web-server
