Neo4j 2026 Community on Ubuntu 24.04

## Neo4j 2026 Community on Ubuntu 24.04 by cloudimg

Neo4j 2026 Community Edition — the world's most-deployed graph database — built on Ubuntu 24.04 LTS noble for Microsoft Azure and maintained by cloudimg. Used in fraud detection, knowledge graphs, recommendation engines, and increasingly as the backing store for RAG / agentic AI memory and entity-relationship reasoning.

Neo4j switched to calendar versioning (CalVer) in 2025; the 2026.x line is the current production release.
