Nov 1, 2025November 2025: Delivered core platform enhancements for jellyfin/jellyfin, focusing on platform compatibility, parsing accuracy, sorting fidelity, and storage flexibility. Upgraded the project to .NET 10.0, refined network/IP parsing, switched to numeric sorting via CompareOptions.NumericOrdering, and removed the minimum free-space enforcement for temporary and log directories. Implemented robustness improvements for marker file searches and added safe-target checks to prevent follow errors. These changes reduce runtime errors, improve user-facing list accuracy, and enable more flexible resource management, contributing to a more stable, scalable streaming platform.
