[Update] RawTherapee 5.13

"Raw Therapee is cross-platform RAW image file processing program.
It compares well with its more expensive commercial counterparts such as Adobe Photoshop, Lightroom, Bibble Pro, etc., but its user interface has a steeper learning curve.

Raw Therapee lets you apply color correction, image sharpening, and retouching to your RAW image files in a non-destructive way.
Its image sharpening algorithms appear to be superior to some of its commercial peers, and its color correction features lets you make adjustments to a deeper level than similar programs.

Beyond color correction, RawTherapee also provides other in-depth options for RAW file corrections.
This includes things such as pre-processing, pattern noise and chromatic aberration correction.
Batch editing is also supported within the File Browser tab."
