July 2025: PelicanPlatform/pelican delivered critical policy and server reliability improvements. Fixed policy default scopes handling in policies.qdl by using proper set operations and removing an unnecessary default_scopes initialization, then increased Tomcat HTTP header size to 1MiB to support larger requests. These changes reduce policy misconfig risks and improve resilience to large headers, enabling smoother deployments and better reliability for token-heavy traffic. Changes were implemented via small, well-documented commits to ensure traceability and maintainability.
