NEXT RELEASE

• No breaking or major changes.

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
• Changed errors raised under certain circumstances
  • ConfigurationError if the passed auth parameters is not valid (instead of AuthError)
    • This improves the differentiation between DriverError for client-side errors and Neo4jError for server-side errors.
  • access_mode configuration option
    • ValueError on invalid value (instead of ClientError)
    • Consistently check the value (also for non-routing drivers)
  • neo4j.exceptions.UnsupportedServerProduct if no common bolt protocol version could be negotiated with the server

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
