9 * \section Sec_ChangeLogXXXXXX Version XXXXXX
12 * - Added TPI programming support for 6-pin ATTINY devices to the AVRISP programmer project (thanks to Tom Light)
13 * - Added command timeout counter to the AVRISP project so that the device no longer freezes when incorrectly connected

16 * the host as a standard Mass Storage device when inserted
17 * - Added MIDI event packing support to the MIDI Device and Host mode Class drivers, allowing for multiple MIDI events to
18 * sent or received in packed form in a single USB packet
19 * - Added new MIDI send buffer flush routines to the MIDI Device and Host mode Class drivers, to flush packed events
20 * - Added master mode hardware TWI driver for easy TWI peripheral control

22 * as on some models, the channel number is not identical to its single-ended ADC MUX mask
23 * - New Webserver project, a RNDIS host USB webserver using the open source uIP TCP/IP network stack and FatFS library

31 * of elapsed milliseconds
32 * - Inlined currently unused (but standardized) maintenance functions in the Device and Host Class drivers to save space

778 * to use descriptors stored in RAM or EEPROM rather than flash memory
779 * - All demos now disable watchdog on startup, in case it has been enabled by fuses or the bootloader
780 * - USB_DEV_OPT_LOWSPEED option now works correctly

809 * task to be stopped when the USB is not connected to a host or device
810 * - All demos updated to stop the USB task when not in use via the appropriate USB events
811 * - Mass Storage Host demo application updated to function correctly with all USB flash disks
