What's new in cgminer for OS X
Antminer U1 support
Numerous fixes for behaviour surrounding USB errors - pipe and IO errors, and no more attempting to reset the device since it's rarely helpful and occasionally harmful.
Libusb and libusbx have finally reconciled their differences and merged all their fixes together into a new official libusb release, so the main change in this version is updating the core code to include this latest libusb. Hopefully this might increase compatibility with some USB3 hubs on windows and make it more reliable (based on the changelogs I can see in libusb). This is the reason for the minor version number update to 12 as it's quite a substantial code change, hopefully only for the better!
Increased the hashfast overheat limit default to 90 after extensive discussions with the engineers who designed the devices.
Fixed a crash in the nanofury USB stick code.
Fixed the displayed diff shown being wrong when solo mining.
