LibRaw 202502 snapshot is just published in our Github repository. Changes are:
Camera format support

  • OM System 14-bit high-resolution files.
    Note: the new decoder supports old (12-bit) Olympus/OM-System files

Submitted by lexa on

  • Support for 4-component JPEG-compressed DNG files
  • CR3-Qstep table: avoid wrong 64-bit code generation
