April 2026 monthly summary for erlang/otp focusing on security-hardening, packaging simplifications, and dependency reliability to improve release readiness and compliance. Delivered CI/CD enhancements, release automation, and packaging improvements across OTP and Stdlib, with notable fixes to the release flow and permissions model. Business value includes stronger security posture, reduced release risk, simpler packaging, and faster, more reliable merges and deployments. Key achievements: - OTP: Dependency pinning and scorecard compliance — pinned dependencies where appropriate, added a missing recompilation file, and fixed pin SHA; scorecard no longer flags unpinned deps in common scenarios. (commits 9c8b4b810b827da0409df88fe47ee86fccb39ed9; 37cc54fc9bd031d47f55f8428a85e8119b86d3b7; 1f622b05907797b738535f627da4b40a05e7860e) - Stdlib: packaging and test improvements — removed a binary-based test and created a jar file from a test script to simplify packaging. (commits c455122e8ed80ef5e754b4e9ce518f9531594558; db8364b9c7f1c61281095e9100fd1b63bcf72e6a) - OTP CI/CD workflow hardening and security — tightened GitHub Actions permissions to a safe default, added explicit required permissions, adjusted system-test dependencies, introduced a new build-otp workflow, and fixed template expansion to prevent code injection; updated GH Actions SHA. (commits be7fa3a8c573dcc0f71f3fd30da8058ad70a3f73; d9613a548d541c76df7fa0d79b9735eaca3b4287; 8d07effb7174af666a9e3f657833d742b1a8a052; 477751c3c5f0c129851912a6a2e665dfff64aa57; 1ee6d75f977536a99f5531e674d67391b7841051; 7ea0b5e00fd16fda5dff88093bc283001bdd46dd; 1fecc75236419c0c3ca4b12ef25ae13d92cd238d) - Release workflow and CI/config cleanup — added ratchet version to release workflows, fixed shell/script issues across Windows and Bash, corrected release artifacts handling, improved permission provenance, and introduced a ruleset-check in main.yaml to ensure deterministic gatekeeping. Notable commits include ratchet version, Bash/Powershell fixes, and release file handling. (commits 9e2f2d01d425d716fc673ced934586272c4959d7; e9c8b9a69b675ceee72b2b7ce211875c935ad001; 8f603eaa0a55cadaa42d732c8c45c8bd02e98cc4; 516b688a06558004bfccf21b638fc1dcab18c8ba; ce43bdc7e853cc2cb16a6d2dd727746a574251aa; d33a0e98e36093c260c5a3553142d7de3e6220f0) - CI/config cleanup and feedback integration — improved naming conventions and removed unnecessary variables; incorporated feedback into workflow refinements. (commits 4dfd69e085b50a282ce2c3655759e010c0a6aa6d; f3696e9cad4526fc6287cb2404a35b50ed2dfed4; f5464a64ef3ebcebee72fcd378de54569e7b40f4) Overall impact and accomplishments: - Strengthened security and compliance posture (scorecard, explicit permissions, safe defaults) while preserving release velocity. - More reliable, deterministic release and packaging workflows, reducing risk of broken releases or missing artifacts. - Improved maintainability through CI/config cleanup, clearer naming, and actionable feedback integration. Technologies/skills demonstrated: - GitHub Actions workflow design and hardening, permissions management, and release automation. - Shell scripting and cross-platform scripting considerations (Bash and PowerShell) and mitigation of template injection risks. - Dependency pinning strategies balanced with practical exceptions for frequent_sha changes (container image workflows). - Packaging simplification (jar creation from test scripts) and test modernization. - Scorecard compliance and fork handling strategies for better gatekeeping.
