Liquigraph started when the first versions of Neo4j 2.0 were released. The project was still going towards 1.0 and release candidates were pushed. Time has passed, several major versions have been released and a new JDBC driver, for Neo4j 3.x, has been designed. This new JDBC driver is not feature-complete yet and cannot replace entirely the legacy JDBC driver (see this usecase matrix for more details).
See in the table below to pick the right Liquigraph version for your usecase.
|Liquigraph version||Neo4j version||Underlying JDBC driver||Supported connection modes|
|2.x||2.x||Legacy JDBC Driver (fork)||Embedded (2.x), HTTP (2.x)|
|3.x||3.x||Official JDBC Driver||HTTP (3.x), Bolt (3.x)|
|4.x||4.x||Official JDBC Driver||HTTP (4.x), Bolt (4.x)|
