This is a new disk image format. Not even a disk format. For virtualizing a disk.
On which you can put a filesystem, yes.
There seems to be an extraordinary amount of confusion in many of the comments, I don't know why.
Only Mac users IMHO are well-familiar with working with disk images. They are not as diverse or well-supported on other OS’es, while nearly every Mac app (prior to the App Store) was installed by dragging it out of a mounted disk image.
Just reading the title, I was like, I hope it is an update to encrypted sparse bundles, and it is.

Yes, its going to be similar to a .dmg file on the Mac.

We really don't have enough disk formats in this space. Is this bringing something new ? Or is just polluting the namespace.
>Is this bringing something new?
If only there was a whole post available so one could find out...
The post only benchmarks against UDIF. Whether this brings something new is a very good question that is not answered by the post.
How complex is the format? Did they do anything clever? Did they engage in NIH? For all I know they switched the AES mode and made the blocks bigger and that's the entirety of the performance boost.
