Version 5.3.0 2024-04

Version 5.3.0 2024-04

Version 5.2.1 2023-12

• Add options to inspection script to skip heavy operations - rel props or cardinality inspection #767
• Fixes database version parsing issues
• Fixes bug when combining count with pagination #769
• Bumps neo4j (driver) to 5.15.0

Version 5.2.0 2023-11

• Add an option to pass your own driver instead of relying on the automatically created one. See set_connection method. NB : only accepts the synchronous driver for now.
• Add a close_connection method to explicitly close the driver to match Neo4j deprecation.
• Add a DATABASE_NAME config option, available for both auto- and self-managed driver modes.
• Add neomodel_inspect_database script, which inspects an existing database and creates neomodel class definitions for all objects.
• Add support for pandas DataFrame and Series ; numpy Array
• Add relationship uniqueness constraints - for Neo4j >= 5.7

Version 5.1.2 2023-10

• Raise ValueError on reserved keywords ; add tests #590 #623
• Add support for relationship property uniqueness constraints. Introduced in Neo4j 5.7.
• Fix various issues, including fetching self-referencing relationship with same name as node labels #589
• Bumped neo4j-driver to 5.12.0

Version 5.1.1 2023-08

Version 5.1.1 2023-08

• Add impersonation
• Bumped neo4j-driver to 5.11.0
• Add automatic path inflation #715
• Improve code quality and tooling

Version 5.1.0 2023-07

Version 5.1.0 2023-07

• Bumped neo4j-driver version to 5.10.0
• Breaking change : When using neomodel along with Neo4j version 5, use StructuredNode and StructuredRel's element_id property instead of id. If you have Cypher queries which currently use the id() function, migrate them to elementId() instead.
  If you use Neo4j version 4.4, this change should be transparent to you, and you should keep using id() function in Cypher since elementId() is not implemented in 4.4.
• Bump Shapely to >= 2.0.0
• Fix schema scripts invocation
• Removed custom str method, part of NodeClassRegistry, from Database() (db) object.
