Oct 1, 2025October 2025 CS-SI/eodag monthly summary focused on reliability and stability of provider configuration parsing and data access workflows. Delivered a critical fix to Providers.yml by correcting the escape character for a plus sign within a string literal, ensuring proper parsing of provider configurations and preventing runtime errors in provider setup or data retrieval. This change reduces failures, support tickets, and improves consistency of data access across providers.
