 #### Note regarding Java 1.8.x support:
+v24.0.0 features an upgraded protoc-protobuf dependency that requires an upgrade to JDK 11. This version is incompatible with Java 1.8 and and requires an upgrade to Java 11.

+The following is only applicable to dgraph4j versions < v24.X.X. 
 * If you aren't using gRPC with TLS, then the above version table will work for you with Java
  1.8.x too.
 * If you're using gRPC with TLS on Java 1.8.x, then you will need to follow gRPC docs [here
