Sep 1, 2025Month 2025-09 — Delivered stability-focused feature improvements and a critical code clarity fix in FreeCAD/FreeCAD. Implemented non-recursive freeze/unfreeze behavior applied to the selected object with read-only properties enforced when frozen, improving data integrity and preventing unintended mutations. Renamed DeriVector2::crossProdNorm to DeriVector2::crossProdZ to accurately reflect the z-component cross product when treating 2D vectors as 3D, enhancing code clarity. Overall impact includes reduced risk of cascading freezes, safer data states for users, and clearer math semantics that streamline future Sketcher and core enhancements.

Mar 1, 2025During March 2025 (2025-03), delivered cross-module core-property protection and improved file-save reliability in FreeCAD/FreeCAD. Implemented a new 'locked' attribute in property definitions and propagated core-property protections across 11 modules (DocumentObject, Assembly, BIM, Draft, FEM, Measure, OpenSCAD, Part, PartDesign, Points, TemplatePyMod) to prevent deletion or modification of core properties, thereby boosting data integrity and stability. Enhanced save operations with richer error messages from the writer and added system-level checks (disk space, access issues) to report failures during writes, addressing FreeCAD#19588 and reducing data loss risk. These changes improve reliability, user trust, and debugging efficiency, while showcasing strong cross-module collaboration and maintainability.
