March 2026 monthly summary for validmind/validmind-library focusing on CI/CD reliability and automated release workflows. The key accomplishment is fixing the release tag trigger by switching from the default GITHUB_TOKEN to a Personal Access Token (PAT), enabling downstream workflows to trigger correctly on tag pushes. This change improves release automation, reduces manual steps, and supports continuous delivery of PyPI artifacts.

October 2025 monthly summary for validmind/validmind-library focusing on release automation improvements and CI/CD modernization. Key feature delivered: Tag-based Release Workflow replacing the prior branch-promotion approach. This feature reads the project version directly from pyproject.toml, creates a vX.Y.Z tag, and generates GitHub release notes automatically. It also updates PyPI publishing to trigger on tag pushes (vX.Y.Z) instead of the previous release_prod workflow dispatch. Additionally, obsolete release workflows (release_prod.yaml and prod_patches_to_main.yaml) were removed to simplify maintenance. Major bugs fixed: No major bugs reported for this repository in October 2025. Overall impact and accomplishments: The new tag-based release workflow reduces manual steps, increases release determinism, and accelerates time-to-market by automating tagging, release notes, and PyPI publishing. This improves traceability and reliability of production releases, aligning with semantic versioning and CI/CD best practices. Technologies/skills demonstrated: GitHub Actions, YAML-based CI/CD pipelines, pyproject.toml version parsing, semantic versioning, automated Git tagging and release notes, PyPI publishing automation, and cross-team collaboration.
