I think Jeremy had originally planned this for mid-year release last year in 2011 but got sidetracked.

But yeah, it's (vaguely) weird that nobody at FreeDOS mentioned it. This is the first I'm hearing of it being actually released, heh.

Accidentally? omitted from previous versions, needed for CHCP.

Rufus "DOS-on-USB-installer" dude, basically shutting up some scary warnings.

Partial hack to hopefully begin work for 4k sector HDs ("teh futurez").

Probably suggested by Bernd as he heavily uses things like that.

You must've missed the long discussion on the FD mailing lists. One guy ("Czerno"? aka "Grandpied"?) wanted to test on his 4 kb sector USB hard drive or whatever and was hacking the Panasonic USB driver, MS-DOS, etc. So Jeremy whipped up a partial hack (after having barely tested with TDSK) for him. That's all I recall. Search the online archives for more info.

Basically, according to the dude, he says the hard drive industry will basically phase out 512-byte sectors after 2015 (?) or such for various political and technical reasons. So he's saying it may be wise to plan for the future. (Though I think we've got bigger problems with UEFI, but anyways ....)
