    Release Notes: A number of bugs were fixed, including leaving the camera in an unpredictable state when an I/O error occurs. The project's own reimplementation of the old libusb interface (IOCTL_USB_BULK) is used instead of the new URB interface, which is 20% to 50% slower and sometime leads to I/O errors. File time preservation across download was added. Better capture support was added. A bug that caused files over 2MB to be corrupted while downloading was fixed. The --loop-capture feature was added. Configure errors and parralel build with make -j were fixed.
