Workflow Changes ============================================================= 

The following changes may disrupt established workflows for the connector.

1.1.0 ------------------------------------------------------------------------

Version History ==============================================================

1.0.2 ------------------------------------------------------------------------

Released 2022-08-30

Enhancements & New Features

 * [NEOO-132] Cypher-backed Views
   
   You can now define views based on a Cypher query. To use Cypher-backed 
   Views, in the connection string, specify the full path to the View 
   Definition file using the ViewDefinitionFile property. For more 
   information, see the Installation and Configuration Guide.

 * [NEOO-64] Join passdown support

   The connector now supports join passdown. When a JOIN clause is 
   provided in the SQL query, it is now passed down to the Neo4j server, 
   which performs the calculation. This feature improves performance for such 
   queries. For more information, see the Installation and Configuration 
   Guide.

 * [NEOO-43] Query timeout

   Query timeout, using course granularity, is now supported. Cypher query
   executions, and certain SQL Engine processes cannot be timed out, however.

   When retrieving data, you can now cancel the operation. Cypher query 
   executions cannot be cancelled, however.

   The connector has been updated to use version 1.1 of the RapidJson 
   dependency.

 * [NEOO-136] Updated Neo4j Go Driver

   Previously, the connector used version 4.3.


1.0.1 ------------------------------------------------------------------------

Released 2022-05-13

Enhancements & New Features

 * [NEOO-60] Distinct passdown support

   The connector now supports distinct passdown. When a DISTINCT clause is 
   provided in the SQL query, it is now passed down to the Neo4j server, 
   which returns unique rows. This feature improves performance for such 
   queries.
   
 * [NEOO-61] Sort passdown support

   The connector now supports sort passdown. If an ORDER BY clause is provided 
   in the SQL query, it will be passed down to the Neo4j server, which will 
   perform sorting. This feature improves performance for such queries.
   
 * [NEOO-62] Aggregation passdown support

   The connector now supports aggregation passdown. If an aggregate function 
   is provided in the SQL query, it will be passed down to the Neo4j server, 
   which will perform the calculation. This feature improves performance for 
   such queries.
   
 * [NEOO-128] Updated OpenSSL library
   
   The connector has been updated to use version 1.1.1n of the OpenSSL 
   library.
