Jun 1, 2026June 2026 monthly summary for SpecterOps/BloodHound. Delivered key enhancements to node kind data integrity and schema flexibility by backfilling custom node kinds for schemaless nodes and relaxing the kind array minimum items, improving data representation, usability, and downstream analytics. Carefully managed backward compatibility by reverting a previous minItems adjustment on the OG node schema. These changes reduce data gaps, enable more flexible node definitions for customers, and support more accurate security graph modeling. Implemented and validated changes with targeted commits to ensure traceability and stability. Technologies involved include schema design, data backfill, and code hygiene practices across the repository.

Feb 1, 2026February 2026 monthly summary for SpecterOps/BloodHound: Delivered consolidation of OpenGraph pathfinding gating to improve reliability and reduce misconfiguration. Pathfinding now runs only when the required schema tables are populated and is gated by the opengraph_extension_management feature flag. This simplification eliminates the separate pathfinding flag and reduces deployment risk.
