Over six months, Jan Pišl contributed to FreeCAD/FreeCAD and prometheus-community/helm-charts by delivering targeted feature enhancements, codebase cleanups, and stability improvements. He modernized the Prometheus Postgres Exporter Helm chart using Kubernetes labeling best practices and maintained semantic versioning. In FreeCAD/FreeCAD, Jan refactored the Sketcher geometry history configuration, improved UI/UX sorting, and streamlined CMake build configurations by removing obsolete macros and dead code. He addressed Qt compatibility by updating conditional compilation for newer Qt releases and stabilized unit tests for pressure conversions. His work demonstrated depth in C++, Python, and build system management, consistently improving maintainability and onboarding for contributors.

November 2025 (2025-11) - FreeCAD/FreeCAD: No new features released this month; main focus on correcting unit test values for pressure conversions and stabilizing the test suite to prevent regression in core unit handling. The primary deliverable was a fix to the Imperial pressure test expectation, ensuring accurate testing of psi to MPa conversions.

August 2025 monthly summary for FreeCAD/FreeCAD focusing on codebase hygiene and stability. Completed removal of the unused DAGFilter from the GUI, including deletion of related source/header files and updates to build configuration. Cleaned references in DAGModel.cpp and adjusted CMakeLists.txt to reflect the simplified codepath. The change reduces dead code, shortens the GUI code path, and lays groundwork for future refactors without altering user-visible behavior.
