 ## [Unreleased]
 
+### Added
+
+- Added NV12 stream format parsing for UVC uncompressed descriptors.
+
 ### Fixed
 
 - Fixed regression from version 2.5.0 where unreasonably large URBs could be allocated, leading to out-of-memory scenarios. Now, if urb_size == 0, we allocate URB of size 4x MPS. For other urb_sizes, user's value is used to provide flexibility.
+- Fixed unsupported UVC formats leaking into the frame list when descriptor parsing returns an invalid format.
