February 2026: Delivered FMU build optimization for OpenModelica by simplifying the FMU runtime header handling in CMake, reducing header surface area and streamlining the build process for faster compilation and easier maintenance.

Month: December 2025 (2025-12). Focused on stabilizing UI initialization for Qt 6.10 in OpenModelica. Delivered a compatibility fix to the coordinate system initialization flow, preventing build failures and preserving existing behavior across Qt versions. This work reduces downstream maintenance costs and improves cross-version reliability for users upgrading to Qt 6.10.

October 2025 monthly summary for ERGO-Code/HiGHS: Implemented API usability improvement by introducing named callback data structures in public headers, enabling forward declarations and clearer API usage. This change enhances developer experience and reduces integration risk for downstream users, aligning with product goals for more maintainable, extensible APIs.

September 2025 focused on delivering reproducible builds and enabling HPC-based model evaluation. Delivered a new 'othpc' tool in the staged-recipes repository to evaluate simulation models on SLURM-based HPC clusters, and improved OpenModelica build reproducibility by pinning bootstrapping sources to a tarball. These changes enhance reliability, speed up validation, and reduce CI churn across conda-forge and OpenModelica.

June 2025 highlights for ERGO-Code/HiGHS: Improved build clarity and CI efficiency through targeted build-system refinements. Delivered a corrected CMake build status message, and implemented Unity Build support in CMake with CI integration. Targeted adjustments (disable for several targets, skip a source) resolved redefinition issues while preserving speedups. Result: quicker feedback loops, reduced user confusion on outputs, and more reliable builds across targets.

April 2025 monthly summary focusing on stability and build reliability for OpenModelica/OpenModelica. Delivered a critical backend build fix by linking the expat library (FMIL namespace) to omcbackendruntime, addressing a blocking build failure and improving CI reliability. This work enables downstream backend features and smoother integration with FMIL-based components.
