Oct 1, 2025

Month: 2025-10 | For the spm/spm repository, the month focused on delivering a reusable asset workflow and strengthening CI to support the latest Matlab release. Key features delivered: - Save Generated Logos as PNG: Added a save option to spm_logo.m that saves the generated logo as spm_logo.png when the input flag S.save is true, using saveas. This enhances asset reusability and streamlines downstream usage across projects. Commit: b385fe... (Enhancement: added save option to spm_logo.m). - CI Improvement: Support Matlab R2025a: Updated GitHub Actions workflow to expand the matrix to include Matlab version R2025a, ensuring testing against the latest Matlab release for compatibility and reliability. Commit: c66a321... (Updated Github Actions for Matlab 2025a). Major bugs fixed: None reported this month. Overall impact and accomplishments: - Business value: Faster asset generation and reuse (logos), reduced manual steps, and a more reliable CI pipeline that aligns with customer environments. - Technical accomplishments: MATLAB function enhancement, automated asset export, and version-aware CI matrix updates that mitigate regression risk. Technologies/skills demonstrated: MATLAB scripting and file I/O (saveas), feature flag handling, GitHub Actions CI matrix expansion, cross-version compatibility testing, and release engineering.

April 2025 for spm/spm: Focused maintenance on installation guidance reliability. Core effort: fix Installation Link Path issues in spm_check_installation.m so that, on compilation failure, users land on the correct installation docs, including platform-specific anchors. This reduces dead links and accelerates onboarding for new users and developers.
