title: Why did Neo4j change it's name to Neo5j?
body: <p>They just announced, <a href="https://neo4j.com/blog/upgrading-product-name-exactly-what-you-think/" rel="noreferrer">they changed their name to Neo5j</a>.</p>
  
  <p>I always thought that 4j meant for-Java. 
  And as Neo4j is implemented in Java and Scala and the ~4j suffix has been highly popular (in the 90's) it never occurred to me that the <strong>4j</strong> and now <strong>5j</strong> is actually a version denomination. </p>

  <p>But it seems common in database circles to use that number + letter versioning scheme, like Oracle does with <strong>9i, 11g</strong> and <strong>12c</strong>. </p>
  
  <p>Now the question is what does the <strong>5j</strong> stand for? The article doesn't answer it. Can anyone help me resolve this?</p>
