February 2026 monthly summary for spm/spm: Delivered targeted bug fixes and test infrastructure enhancements that improve numerical accuracy, cross-version compatibility, and test reliability. These work items reduce runtime errors in MSP source localization, extend MATLAB compatibility, and provide clearer diagnostics during CI runs, contributing to product stability and faster issue resolution.

January 2026: Focused on performance optimization in the spm/spm repository. Implemented a targeted refactor of the spm_logdet function to remove overhead from a try...catch error path by replacing it with a conditional check on the number of input arguments. This change reduces exception handling overhead in the hot code path, improving runtime speed for common usage patterns. The work was tracked as a feature in spm_logdet.m with commit a72ec615d5b51a0066f4ba9dbed2ef32f9f3c504. This aligns with performance goals and improves scalability for larger datasets.

January 2025 monthly summary: Focused on strengthening the SPM installation experience for MATLAB users through enhancements to the spm/spm-docs documentation. Delivered clear version compatibility, standalone package contents, and MATLAB Runtime installation examples to reduce installation errors and support onboarding. No major bugs fixed this month; emphasis was on documentation quality, reliability, and developer-facing guidance. This work improves user confidence, reduces support overhead, and aligns with product readiness goals.
