Sep 1, 2025September 2025 monthly summary for i4Ds/Karabo-Pipeline. The CI/CD foundation was significantly modernized, delivering a robust, maintainable automation strategy for GitHub Actions and Conda builds. A new main workflow was introduced, replacing the legacy workflow to streamline CI, and a dedicated conda-build-test workflow was created and iteratively refined to ensure reliable conda build validation across environments. The conda-build CI configurations were updated extensively to improve build steps, YAML reliability, and release readiness. These changes culminated in a more predictable release process and faster feedback for developers.
