Free, open-source software RawTherapee has been updated to version 5.8, the team behind the product has announced. This is a relatively small update, at least as far as general users are concerned. RawTherapee 5.8 brings a new tool called Capture Sharpening that automatically recovers the detail lost due to diffraction/lens blur.

The RawTherapee team explains that Capture Sharpening can be used with Post-Resize Sharpening in order to produce 'detailed and crisp results.' The tool is found within the 'Raw' tab.

In addition, RawTherapee 5.8 adds support for Canon's CR3 raw image format. The team says that at this point in time, RawTherapee can decode the image data so that users can process these image files; it cannot, however, retrieve the metadata. Though it's not explicitly stated, it appears the team plans to add metadata support for these files in the future.

Those two features aside, the new update brings various improvements to camera models, optimizes tools, speeds up the application, improves its memory management and fixes a number of unspecified bugs. RawTherapee 5.8 can be downloaded for Windows, Mac and Linux from the software's website.
