Monthly summary for 2025-10 focused on stabilization of the Graylog2 server development baseline. No new features were released this month. Major action: reverted the graylog2-server version to 7.0.0-SNAPSHOT to undo a prior version bump and restore a stable development state. This change minimizes risk to CI/build pipelines and downstream workflows while enabling resumed feature work on a solid baseline. The revert is captured in commit f48396ab1ad4c170f140ff7fbe16015b293d366d with the message "Revert version to 7.0.0-SNAPSHOT".

April 2025 – Graylog2-server: Delivered five core features enhancing plugin flexibility, security, and developer experience. Implemented keep_value in EncryptedFieldValue for safer encrypted data handling; added titles to pluggable login forms to clarify authentication flows; introduced NonApiResource to support non-API plugin resources; set up /sso proxy context prefix in DevServer for development routing; and added ContextClassLoader utilities (Switcher and LoggingClassLoader) to improve plugin loading management and debug visibility. This work improves business value by enabling flexible integrations, safer data handling, clearer user experiences, and faster development cycles. Note: no explicit bug fixes were recorded in this data set.

March 2025 delivered reliability improvements for plugin support in Graylog2-server. Implemented a class-loading fix for ObjectMapperModule to enable plugin-provided types to be discovered at runtime by passing a ChainingClassLoader, and tightened initialization to require a ClassLoader, with test scaffolding preserved. These changes reduce runtime class-loading errors, improve plugin reliability, and enhance testability, delivering business value through more stable plugin functionality and safer deployments.
