I received the following message from DxO today. As I read it, the suggestion seems to be that past support for mRAW files was inadvertent, but they are working on an ‘officially’ supporting these file formats for a future release.
You have recently updated to DxO PhotoLab 6.14 and since then you can no longer edit some of your images with the message that Sony mRAW and sRAW is not supported.
As a side effect of other features, it was temporarily possible to open Sony mRAW files and cropped RAW files (that become mRAW files), though Sony mRAW was officially never supported nor can we guarantee, that the image quality meets our standards.
As part of the continuous development of our software and in particular the RAW converter, this undocumented feature is no longer available. Our R&D team is actively working on addressing the issue with mRAW files and Sony cameras. The temporary downgrade offered aims to ensure users can continue using the software without interruption. We are committed to finding a comprehensive solution to fully support these formats and enhance your experience with our software. Thank you for your patience and understanding as we work towards resolving this matter.
You can load the previous version of your software from this link:
DxO PhotoLab 6.13: Windows
We apologize for this inconvenience and will inform you as soon as we have a fix.
Kind regards,
DxO Labs Support Team
