v0.4.0 - Neo4j Knowledge Graph Skill

This release adds an open-source Codex/agent skill for Neo4j knowledge graph work.

Added:

• skills/neo4j-knowledge-graph/ with SKILL.md and OpenAI agent metadata.
• References for spreadsheet-to-graph modeling and safe Cypher/vector-index/GraphRAG patterns.
• profile_table.py utility for profiling CSV/Excel files before graph modeling.
• Tests for the profile_table.py utility.

Changed:

• Linked the skill from English and Chinese README files.
• Extended maintenance checks to compile and test the skill utility.
• Added GitHub topics for graphrag, codex-skill, and ai-agents.

Validation:

• Skill validator passes.
• Modern example tests pass.
• Skill utility tests pass.
• Python compile checks pass.

v0.3.1 - Project Positioning Polish

This release improves the project positioning without changing the repository slug.

Changed:

• Updated the README display title to Excel to Neo4j Knowledge Graph.
• Kept the historical repository slug neo4j-python-pandas-py2neo-v3 for continuity and existing links.
• Reworked the English and Chinese README introductions to frame the project as both a legacy py2neo v3 example and a modern Neo4j GraphRAG/vector-search example.
• Updated GitHub repository description to match the clearer positioning.

No runtime behavior changed.

v0.3.0 - Modern Neo4j GraphRAG Example

This release adds a modern Neo4j example based on the original invoice Excel project.

Added:

• examples/modern_invoice_graphrag/ with English and Simplified Chinese docs.
• Official neo4j Python driver integration through a CLI.
• Neo4j vector index and db.index.vector.queryNodes search Cypher.
• Deterministic local embeddings for keyless dry-runs and CI.
• Optional neo4j-graphrag[openai] requirements for production GraphRAG embeddings.
• CSV sample data that runs without pandas or external services.
• Offline unit tests for invoice normalization, embeddings, Cypher, and CLI helpers.

The legacy py2neo v3 example remains unchanged. This release adds a current Neo4j 5+/2026 GraphRAG/vector-search path without breaking existing users.

v0.2.2 - README Language Split

This release cleans up the project documentation for a more professional open-source entry point.

Changed:

• Reworked README.md as an English-first project entry point.
• Moved the full Simplified Chinese documentation to README.zh-CN.md.
• Added language switch links between the English and Simplified Chinese docs.
• Removed mixed-language duplication from the main README while keeping Chinese documentation available for existing users.

This is a documentation-only release.

v0.2.1 - OSS Maintenance Metadata

This release fills in the standard open-source maintenance metadata needed for a healthier public repository.

Added:

• MIT license.
• CONTRIBUTING.md, SECURITY.md, SUPPORT.md, and CODE_OF_CONDUCT.md.
• GitHub issue templates for bug reports, compatibility questions, and sample-data requests.
• Pull request template and CODEOWNERS.
• Lightweight GitHub Actions syntax check.
• README links for governance, support, security, and contribution paths.

This keeps the project positioned as an actively maintained legacy py2neo v3 / Neo4j 3.x educational example while dependency modernization remains tracked in #23.

v0.2.0 - Maintenance Restart

This release marks the restart of active maintenance for neo4j-python-pandas-py2neo-v3.

Highlights:

• Documented the current maintenance status and roadmap.
• Added compatibility notes for the original Python 3.6.5 / Windows 10 / Neo4j 3.x / py2neo 3 environment.
• Added quick-start guidance for Invoice_data_Demo.xls, local path setup, and Neo4j credentials.
• Added CHANGELOG.md for future release tracking.
• Started historical issue triage, closing resolved sample-data and compatibility questions while leaving the remaining reproducible compatibility issue open for follow-up.

This remains a legacy py2neo v3 educational/example project. Modern Python, pandas, Neo4j, and py2neo compatibility work is tracked in the README roadmap.
