Why did Neo4j change it's name to Neo5j? : <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><a href="https://i.stack.imgur.com/8PwiB.png" rel="noreferrer"><img src="https://i.stack.imgur.com/8PwiB.png" alt="enter image description here"></a></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>
