## What's New (1.6.6-mt1, November 24, 2015)
15+
16+
* New documentation section 'Special Notes'. Please read!
17+
* Updated ASCII pinouts to be more readable and less ambiguous.
18+
* Updated the Signed driver for Windows (extras directory).
19+
* adds CDC/MIDI/HID, CDC/MSD/HID, and CDC/MSD/MIDI/HID composite USB devices.
20+
* Of the above, currently only CDC/MIDI/HID is usable (see MIDIUSB library).
21+
* Merged in changes from upstream past SAMD CORE 1.6.2 release
22+
* Added SPI.transfer16(..) method
23+
* Bugfix: added missing Serial.begin(baud, config) method. Thanks @tuxedo0801
24+
* the pin mode is changed to INPUT mode, arduino/ArduinoCore-samd#28
25+
* HardwareSerial BUG Rx pin floating input, arduino/ArduinoCore-samd#48

## Special Notes
65+

* Boards Manager may require opening twice (with possibly a delay in between) to see some updates.
67+
68+
* Errors when compiling, uploading, or burning the bootloader
69+
Be sure to install the Arduino samd core before installing the MattairTech samd core. If you have problems upgrading
70+
the IDE to 1.6.6, you may need to uninstall both the Arduino and MattairTech cores, then re-install in the proper order.
71+
Use Arduino core 1.6.2 or above.
72+
73+
* Tools->Communications menu
74+
Currently, the Tools->Communications menu must be used to select the communications configuration. This configuration
75+
must match the included libraries. For example, when including the HID and Keyboard libraries, you must select an
76+
option that includes HID (ie: CDC_HID_UART). This menu is currently needed to select the USB PID that matches the
77+
USB device configuration (needed for Windows). This may become automatic in a future release.
78+
79+
* Be sure that the Tools->Communications menu matches the sketch and libraries you are compiling.
80+
* Different combinations of USB devices will result in different COM port assingments in Windows.
81+
82+
* Incude platform specific libraries
83+
You may need to manually include platform specific libraries such as SPI.h, Wire.h, and HID.h.
84+
85+
* Differences from Arduino in versioning
86+
The MattairTech ArduinoCore-samd version currently tracks the IDE version. In some cases, it may indicate the
87+
minimum IDE version. This is the case for both 1.6.5-mtX and 1.6.6-mtX (which corresponds to SAMD CORE 1.6.2).
88+
1.6.6-mt1 corresponds to Arduino SAMD CORE 1.6.2 plus some pull requests.
