See also https://github.com/neo4j/neo4j-python-driver/wiki for a full changelog.

NEXT RELEASE

• No breaking or major changes.

Version 6.4

• Python 3.15 support added.
• Deprecate configuring drivers with URIs containing a path (e.g. neo4://example.com/some/path) or fragment (e.g. neo4://example.com#some-fragment).
  This information is currently being ignored anyway. This deprecation will be turned into an exception in a future version.

Version 6.2 - 6.3

• No breaking or major changes.

Version 6.1

• Python 3.14 support added.

Version 6.0

• Python 3.7, 3.8, and 3.9 support has been dropped.
• Remove deprecated package alias neo4j-driver. Use pip install neo4j instead.
• Remove setup.py. Please use a recent enough packaging/build tool that supports pyproject.toml
• Remove deprecated modules:
  • neo4j.conf
  • neo4j.data
  • neo4j.meta
  • neo4j.packstream
  • neo4j.routing
  • neo4j.time.arithmetic
  • neo4j.time.clock_implementation
  • neo4j.time.hydration
  • neo4j.time.metaclasses
  • neo4j.work
  • neo4j.work.query
  • neo4j.work.summary
• Remove deprecated exports from neo4j:
  • log, Config, PoolConfig, SessionConfig, WorkspaceConfig (internal - no replacement)
  • SummaryNotificationPosition (use SummaryInputPosition instead)
• api.Version has been removed as it's unused now.
  ServerInfo.protocol_version now is a tuple[int, int] insteadof a api.Version. This should be drop-in replacement is most cases:
  • Version was a sup-type of tuple[int, int]
  • ServerInfo.protocol_version was already documented and typed as tuple[int, int]
  • Version's additional methods were undocumented and shouldn't have been used
