Concise July 2025 monthly summary for ubicloud/runner focusing on business value and technical achievements.

June 2025 — Actions Runner Controller: implemented default metrics exposure to prevent crashes when metrics config is missing; ensured metrics are exposed by default, improving reliability and observability. This change reduces risk of nil pointer dereferences and simplifies monitoring setup for deployments.

May 2025 summary for ubicloud/runner: Significant authentication and release-management enhancements delivered to improve deployment reliability, security, and speed of migrations. Implemented selective error suppression during auth migration, background token-claims consistency checks, and authv2 integration in runner configuration. Completed environment, tooling, and release readiness work to support the 2.324.0 release, including runtime/tooling upgrades, automated dependency updates, TLS verification bypass control, and formal release notes/version bumps.

April 2025 monthly summary for ubicloud/runner focusing on simplifying session management, strengthening authentication migration, and hardening security, with clear business value and technical gains. Key outcomes: - Reduced complexity and maintenance by removing broker session creation/deletion logic during message listening, simplifying session management and eliminating related broker migration tests. - Strengthened authentication migration: migration triggers on config refresh, added support for authUrlV2 in Runner/MessageListener, enabled default migration for self-hosted runners, and improved error handling and test coverage. - Security hardening: added JWT PS256 support with RSA-PSS padding; enabled FIPS-compliant cryptography by default (RequireFipsCryptography = true). Impact: - Higher reliability in message listening flows, fewer migration edge cases, and a stronger security posture with modern cryptography standards. Improved test coverage reduced risk of regressions in authentication flows. Technologies/skills demonstrated: - JWT PS256 with RSA-PSS, FIPS cryptography, config-driven migrations, and robust error handling.
