This seems to be a minor upgrade of the recently released version 1.12, mainly fixing some bugs and adding support for more devices (PocketPC with square screens, some custom devices). There should be also some BIOS improvements and improved support for USB keyboards.
There is a (short) list of new/changed features in the thread on the PocketDOS forum (though the forum is down at the moment, so I cannot copy it here).
The demo can be as usually downloaded from the PocketDOS web.
