SAMdisk v3.8.10 by Simon Owen is out since the 18th December.

The utility supports transfers between floppy disks and disk images, and is designed to work with almost any soft-sectored disk format compatible with the PC floppy controller, including some copy-protected formats.

Low-level floppy device access requires the fdrawcmd.sys driver to be installed.

• added read and write support .qdos (QL) disk images
• added --irregular option for blind output image if first track isn't regular
• added --fill to set filler byte for regular formats
• fixed setting perpendicular mode for 1Mbps data rate
• fixed reading directly to single-sided formats from a:/b:
• fixed short data indicator showing on no-data sectors
• fixed raw output not using source format fill byte for missing sectors
• changed raw output to allow blank head 1 to mirror head 0 format

There is also a Samdisk 4.0 beta version on github for windows, linux and MacOS.
