Would be happy to see someday support of new Apple FS

Apple File System supports nearly all of the features of HFS+, and offers improvements over HFS+, including 64-bit inode numbers, 1 nanosecond timestamp granularity, an expansive block allocator, support for sparse files, and a crash protection scheme.

Yep, thought the same yesterday. Do you happen to know if AFS will also be used in DMGs? I assume yes, but just to be sure.

Sorry for the late reply. Nope, still haven't met APFS in DMG

Ok, now it's easy to create DMG with APFS:

hdiutil create -volname myVolume -srcfolder ~/MyVolumeFolder -ov -fs apfs myVolume.dmg

From Apple FAQ:
Q: Is APFS open source?
A: An open source implementation is not available at this time. Apple plans to document and publish the APFS volume format specification.

The DMGs in IPSWs (iOS firmware files) uses APFS since iOS 10.3.
