This release focuses on stability improvements over v3.1.9, reverting the RTSP server to the proven v3.1.9 behavior for enhanced reliability. The cleanup process has been optimized to run every 5 minutes instead of every minute to reduce system noise, while improving VBR stream DTS timestamp handling for more stable recordings. Additional fixes include media file path parsing improvements and reduced log spam from frame rate and timestamp gap warnings. 

This also adds better support for RTSP streams that use VBR (CBR is still recommended).

  * FIX: Reduce log spam for frame rate and timestamp gap warnings
  * FIX: VBR stream DTS timestamp handling for improved recording stability
  * Improve storage management security and validation
