We are working on support for the new Canon CR3 raw format used in some of their latest cameras like the M50, EOS R, 90D, etc.  LibRaw released an update 2 weeks ago that includes CR3 support and we've been able to incorporate it into a pre-release version that we are testing internally.  The CR3 files load without issue but we still have to work out an issue where the embedded EXIF info is not reading properly yet: things like model name, shutter speed, ISO, etc. that are needed for proper raw development.  Hopefully we can get everything working soon but in any case, CR3 support is coming!
