Changelog

Source: NEWS.md

Version 3.1.2

• Vignettes and package website with {pkgdown}

Version 3.1.1

CRAN release: 2026-08-05

• Fix Import with neo4j >= 2025

Version 3.1.0

• Improvement of neo4j result processing

  • API v2: paths handled correctly
  • new possible value for the result parameter: "source". With this value the cypher and multicypher functions return the result as returned by neo4j API. Caution: The format is inconsistent between the two versions of the API.

Version 3.0.0

CRAN release: 2026-05-18

• Use the ‘httr2’ package instead of the ‘httr’ package.

• Add support for the Neo4j Query API v2 (/db/{database}/query/v2), required for Neo4j Aura and available on self-managed Neo4j >= 5.19. startGraph() gains an api parameter ("auto", "tx", "v2"); Aura URLs (*.databases.neo4j.io) are detected automatically and default to "v2". Self-managed instances continue to use the legacy Transactional HTTP API ("tx") unless api = "v2" is set explicitly. Note: with api = "v2", graph nodes expose elementId (a string) instead of the integer id returned by the legacy API.
