Dec 1, 2025December 2025: Release readiness and robustness enhancements for NGWPC/ngen. Implemented extensive submodule updates to align with the 2025-12 RC1 official release across snow17, t-route, and related submodules; prepared RC1 candidate and official release assets, aligning development and release branches. Improved logging reliability and configurability by ensuring NGEN log levels respect configuration files, boosting observability and debuggability. Hardened CSV/JSON data handling in formulation workflows with enhanced error logging for missing/malformed data and explicit exceptions. Added validation for empty CSV forcing files and header checks in CsvPerFeatureForcingProvider, plus error message typo fixes.

Jan 1, 2025January 2025 focused on stabilizing the logging subsystem and improving release traceability for the ngen repo. Delivered a bug fix that reverts a problematic merge and stabilizes the logging system, including removing debug statements, enforcing INFO level, and eliminating stdout/stderr redirection to log files. In parallel, updated release candidate metadata by bumping version to rc-1.1.0 with refreshed date and commit hash to improve traceability for the upcoming release. These changes reduce log noise, stabilize runtime behavior, and accelerate deployment readiness.
