Feb 1, 2026February 2026 — Taylor-CCB-Group/MDV Key features delivered: - Spatial Data Conversion Server Enhancements: Improved functionality and reliability by updating dependencies and pinning setuptools, leading to better performance in spatial data handling. - Standalone MDV Library Build for Web App Integration: Introduced a standalone build option to embed the MDV library in web applications, with build configuration updates and developer-facing documentation. Major bugs fixed / stability improvements: - Dependency stability: Locked setuptools version to prevent regressions and ensure consistent deployments for the spatial data conversion server. - Default server alignment: Updated the default server in spatial data conversion to reduce misconfigurations and improve reliability. Overall impact and accomplishments: - Enhanced reliability and performance of spatial data processing, enabling smoother production workflows. - Lower integration friction for customers through web-embeddable MDV library and clearer build/docs. - Improved maintainability with explicit configuration changes and updated documentation. Technologies / skills demonstrated: - Python packaging and dependency management (setuptools pinning) - Build configuration for standalone web integrations (standalone/jbrowse builds, MDV.js placement) - Documentation and developer-oriented guides for deployment and embedding MDV in web apps - Version control discipline and targeted commits enabling traceability (refs: 69e323c98f4d0dfe83766b3bb70f905068bc6fd5, 0ef9bf31f03ee7cd70ae24d93069f4dcbfa80ad5)

Jun 1, 2025June 2025 (MDV) focused on robustness and backward compatibility in core data access. Delivered a targeted DataStore bug fix that improves filter reliability and reduces edge-case issues for legacy configurations. The change standardizes the noClear filter handling, addressing a case-sensitivity mismatch and ensuring undefined noClearFilters default to false, strengthening filtering behavior across datasets.
