March 2026 monthly summary for neo4j/import-spec: Delivered Vector Types for Property Mapping and Serialization, enabling advanced vector-based properties. Implemented validation to prevent dimensions on non-vector types and updated serialization/deserialization to accommodate new vector types, ensuring reliable data ingestion and round-trip integrity. This work is anchored by the commit 'feat: add vector types (#398)' (83fa31d97157c01cb902c25cf18a43ee16dd4ac4). Business value includes enabling vector-enabled analytics workflows, improving data quality, and accelerating development of AI-assisted features.

January 2026 monthly summary for neo4j/import-spec focused on strengthening code quality, data integrity, and development velocity. Implemented CI static analysis integration with Semgrep and introduced an import data validator to catch invalid characters in node labels and relationship types during imports. Improved artifact clarity by renaming extra-validators to import-spec-extra-validators and adding a module name for consistency, while also rolling back the release from 1.0.0-rc11 to a development snapshot to enable further testing. These changes collectively reduce import errors, improve maintainability, and accelerate safe iteration in downstream tests and releases.
