Nov 1, 2025November 2025 — PelicanPlatform/pelican: Delivered robust improvements across server metadata, downtime handling, authentication resilience, and local metadata management, delivering measurable business value through reliability, security, and maintainability gains. Key changes include dependency-injection for JWKS resolution to fix server metadata getter cycle, refactoring GetServerMetadata to return a structured ServerRegistration object for future extensibility, enhanced downtime management with granular scopes and cross-registry/origin synchronization, introduced authentication resilience with retry logic (up to 3 attempts) and tests, and advanced server local metadata alignment with Registry by introducing ServerLocalMetadata, updating models, and exposing a local-metadata API. These changes reduce risk, improve cross-service data consistency, and provide a clearer API surface for future enhancements.

Sep 1, 2025September 2025 delivered security hardening, reliability, and data integrity improvements across Pelican. Implemented cryptographic key matching with jwk.Equal to replace fragile string comparisons, added debugging support, and tightened consistency across code paths. Enabled CLI-driven server ID generation while preserving UI auto-ID behavior, storing IDs separately with server prefixes. Extended token signing to allow specifying private keys per token, updating CLI flows and tests for greater flexibility. Introduced XRootD auto-shutdown and configuration maintenance with health monitoring and metrics, along with comprehensive tests and docs. Standardized downtime data handling for server ads to ensure empty downtime slices when none, and improved nil/empty case handling with targeted tests. Business value: stronger security, improved reliability, better operability, and clearer ownership of server registrations and signing keys.

Feb 1, 2025February 2025 highlights for PelicanPlatform/pelican: Delivered a unified namespace approach with a server-hostname-based prefix for origins and caches, ensuring consistency in namespace registrations and cache advertisements. Improved container deployments and build hygiene by integrating the xrdhttp-pelican plugin (v0.0.3), cleaning the Dockerfile, removing unnecessary packages, and introducing a configurable PELICAN_USER for privilege dropping. Strengthened test reliability for DropPrivilegeSignaling by resetting test state to ensure clean environments. Hardened security and ownership with permissions changes that are conditional on service enablement and by aligning issuer keys directory ownership with the user returned by GetPelicanUser. Launched a centralized downtime management system with persistent storage, API endpoints, and director integration to manage downtime data across origins, improving availability.
