ISO Loader 0.8.x Beta + preview of DreamShell v4.0 RC 5

[sundance2]

I'm following the development of this new version of Dreamshell with great admiration,
and I'm especially curious about the improved ISO Loader v0.8.x
(note, for reference, my Dreamcast is currently running v0.6.11).

Specifically, for a Dreamcast with a SD Card reader connected via the Serial Port,
what are the main benefits expected from this new version ?

I've been looking at the logs for guidance, and so far,
I've mostly noticed some potential improvements to CDDA support
(which would still be great, since CDDA seems broken on my local version of ISO Loader).
What else could be expected?
