Nov 1, 2025November 2025 (topoteretes/cognee) focused on strengthening data integrity, cross-database compatibility, and test/infra quality to reduce production risk and accelerate delivery. Key outcomes include reliable data deletion flows across vector collections and datasets, expanded delete support for single-database graphs, enhanced test coverage for Neo4j and KUZU, and targeted infrastructure improvements that simplify local runs and improve lint and code hygiene. A version bump to 0.5.0.dev0 signals ongoing maturity and readiness for broader feature parity. Business value realized includes fewer production incidents, faster validation cycles, and broader database support with maintainable, infra-oriented design. Technologies demonstrated include Python-based testing, end-to-end test automation, LLM output mocking, graph databases (Neo4j/KUZU), vector store optimization, and infrastructure-level access control and linting practices.
