Oct 1, 2025Monthly summary for 2025-10: Focused on security posture and transparency for OTP. Implemented an OpenVEX status disclosure for the OTP repository (erlang/otp), declaring that OTP is not affected by CVE-2025-9230, CVE-2025-9231, and CVE-2025-9232. The change is captured in make/openvex.table and committed with 'add openssl openvex statements' (commit 9600cd1fd5701ab03b900d46b3165dad5ba411ea). This work enhances security communication, supports compliance initiatives, and reduces user uncertainty without altering runtime functionality.

Aug 1, 2025Month: 2025-08 | Repository: erlang/otp Concise monthly summary focused on business value and technical achievements. 1) Key features delivered - Licensing compliance for generated code across OpenGL, wxWidgets, and documentation. Consolidated licensing updates, added SGI-B-2.0 and Apache-2.0 headers, updated license folders and approved lists, and improved review processes. This reduces legal risk and accelerates release readiness. Related work spanned OpenGL documentation, wx code generation, and license header hygiene, reflected in commits across c4728997, 623cf75f, 11cbeb9e, eb0b835d, c38626f4, 3e17771f, 14206973, and 1b0da672. - Automated OpenVEX vulnerability statement generation for OTP advisories. Implemented verification, fetching, and generation of OpenVEX statements, plus PR creation for missing advisories and improved VEX handling. This enhances transparency and speeds coordinated disclosures. Commits include ed9a430e, ff62574b, and c96f1ea4d. - CI workflow improvement: correct Renovate actor handling. Adjusted GitHub Actions workflow to correctly identify Renovate’s actor for dependency updates, ensuring reliable processing and fewer false positives. Commit: e8fa19e2cb94. 2) Major bugs fixed - Fixed 'under_investigation' key in openvex.table to ensure accurate vulnerability statuses in OpenVEX data. - Resolved gaps in licensing code generation (wxWindows-free license handling and related header insertions) to maintain consistent licensing compliance across generated assets. These changes were implemented alongside ongoing license review updates (multiple commits cited above). - Corrected wxwidget code generation for the wxwindows-free license to prevent misalignment between generated code and license terms. 3) Overall impact and accomplishments - Reduced legal and security risk by ensuring licensing compliance is enforced consistently for all generated assets, enabling safer distribution of OTP components. - Shortened vulnerability disclosure cycle through automation of OpenVEX creation, verification, and PR workflows, improving trust with users and downstream developers. - Improved CI reliability for dependency updates, leading to more predictable release pipelines and faster integration of upstream changes. 4) Technologies/skills demonstrated - Licensing governance and policy enforcement for multi-licensing environments. - OpenVEX automation, verification, and governance for advisories. - GitHub Actions and CI workflow tuning, with attention to actor identification and reliability. - Automation of vulnerability data pipelines and PR automation for faster remediation. Business value summary: The month delivered a more compliant, transparent, and automated release workflow for erlang/otp, increasing trust with users, reducing legal risk, and accelerating vulnerability response and dependency maintenance.
