November 2025 was focused on strengthening the authentication flow, stabilizing the user experience during login, and reducing backend load through smarter configuration fetching and caching. Key initiatives delivered in Stirling-PDF included a revamped login/session management flow with JWT coordination, a singleton app configuration pattern to prevent duplicate data fetches, and backend/security hardening that improves reliability and JSON-based error responses across API surfaces. The result is a smoother, more secure user experience with lower network and server overhead, ready for scale across customer deployments.

October 2025: Delivered the V2 Authentication System with SSO and rate limiting for Stirling-PDF, modernizing login UX and strengthening security. Implemented support for username/password and SSO login (Google, GitHub) with robust post-login flows, and configured rate limiting to protect endpoints while preserving access to select unauthenticated paths for UX resilience. Added SSO metadata storage (sso_provider and sso_provider_id) and migration-friendly user lookup to prevent duplicate accounts and authentication failures. Completed OAuth2 and SAML2 integrations with dedicated services and handlers, and updated front-end and security layers to reflect the new flow. Introduced configurable rate-limiting properties, a cron-based reset schedule, and a configurable max-requests cap. Backend config visibility and anonymous session utilities were added to improve reliability during outages. Overall, these changes reduce login friction, prevent account duplication, and improve system resilience and business velocity. Closes #3046.

September 2025 monthly summary for Stirling-Tools/Stirling-PDF: Implemented security hardening and reliability improvements to reduce risk and improve user safety.
