v1.8.4

• Bug fixes
  • Fix autodetection of built-in SDCard readers on Linux. These are the devices
    that show up as mmcblk0, etc. You shouldn't have to manually specify them
    any more.
  • Ensure that FAT filesystems created by fat_mkfs are the right size even
    when fwup creates disk images. This adds a write to the very last block in
    FAT filesystem.
  • Fix unit test failures related to improved fsck.fat checks in dosfstools
    v4.2. The failures involved volume labels and having a properly sized disk
    image. These particular issues don't affect real world use of fwup, but were
    concerning since they caused quite a few tests to fail.
  • Documentation updates for building on Apple M1 hardware.
