py2neo-history
Python client library and toolkit for Neo4j
Decision gist · record as of 2026-08-14
Yes, but only as a last resort: install this package if you have a project pinned to a specific py2neo version that has been deleted from PyPI and you cannot upgrade. Do not use it for new projects—use the active py2neo package instead. The package is dormant and explicitly will not receive maintenance beyond version 2021.2.3, so treat it as a one-time compatibility workaround, not a long-term dependency.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires a running Neo4j instance (local or remote) accessible via Bolt or HTTP; no Python version constraint is specified in the package metadata.
- High install friction due to no runtime dependencies but dormant maintenance—last release was 1029 days ago and the package explicitly will not receive updates past version 2021.2.3.
- Use only if you need a specific archived py2neo version; newer projects should use the active py2neo package.

What it is and what it does
py2neo-history is a snapshot of the py2neo Neo4j client library preserved to restore access to deleted version history on PyPI. The original py2neo package supports both Bolt and HTTP protocols for connecting to Neo4j databases and provides a high-level API for graph queries, an ORM layer, and administrative tools. This archive package exists solely to allow projects with strict version pinning (e.g., `py2neo ~= 4.1.0`) to continue installing when those versions are no longer available on PyPI; it will not receive any updates beyond version 2021.2.3.
The package is intended as a compatibility bridge for legacy projects. If your codebase works with py2neo 2021.2.3 or later, you should use the active py2neo package instead. This archive is useful only when you have a hard dependency on a specific older release that has been deleted from the main package index.
Use it for
- Restore builds for legacy projects pinned to py2neo 4.1.x or other archived versions when the original release is no longer available on PyPI.
- Maintain reproducible builds in environments where py2neo version history was lost due to package deletion.
- Provide a fallback for CI/CD pipelines that fail because a specific py2neo version cannot be downloaded from the standard index.
