+* SPI: Added SPI.notUsingInterrupt(...) API
+* Fixed build errors if variant disabled USB
+* Wire: TX and RX buffers are now 256 bytes (previously was 64 bytes)
+* Added samd21e sercom compatibility. Thanks @mitchellpontague
+* Fixed lock ups when outputting to UART during ISR
+* Wire: correct I2C frequency calculations, and allow variant to overide default pull up resistor rise time
+* USB: Fixed build errors when CDC_ENABLED was not set. Thanks @gdsports
+
+SAMD CORE 1.6.17 2017.11.29
+
+* More accurate approximation for multiplication factor of PLL to make 48Mhz. Thanks @joverbee
+* Fix changing trigger mode (RISING/FALLING/...) in attachInterrupt(..) during runtime. Thanks @joverbee
+* Improved ISR response time. Thanks @joverbee
+* USB power current can now be overridden in the variant. Thanks @awatterott

 In particular, this adds support for the Adafruit SAMD Boards such as the Feather M0
 
-## ATSAMD51 Installation on Arduino IDE
-
-The ATSAMD51 is a significantly new chip, so this is a detailed process for now! For the SAMD21, please install via the board manager (no extra steps required)
-
-1. Install Arduino IDE 1.8.5 or greater
-2. Install/update the Adafruit SAMD board support package if you have installed it
-3. Now we need to update CMSIS! Download https://github.com/adafruit/ArduinoModule-CMSIS-Atmel/archive/master.zip and unzip
-4. Find your Arduino CMSIS, in Mac its "~/Library/Arduino15/packages/arduino/tools/CMSIS-Atmel/1.1.0/CMSIS" version # may vary, you'll need "Go to folder..." feature in the Finder to get to " ~/Library/Arduino15" as it is hidden. In Windows it is "C:\Users\yourusername\AppData\Local\Arduino15\packages\arduino\tools\CMSIS-Atmel\1.1.0\CMSIS" Inside is a folder named Device
-
-For Linux: the Arduino stuff is located in ~/.arduino15/packages/arduino/tools/CMSIS-Atmel/1.1.0/CMSIS
-
-5. Inside the downloaded CMSIS zip, go into the CMSIS-Atmel/CMSIS folder, you should see a folder named Device. *DRAG THE DEVICE FOLDER ONLY* from the zip to your arduino Library folder so that Device is merged with Device. It will replace a bunch of files.
-
-For Linux, it may be better to just delete the original Device Folder then copy over the new one - the drag/drop worked ok on MACOS, but not so well on my Linux box.  
-
-6. You will also need to replace bossac. For Windows or Mac: Go here https://github.com/adafruit/BOSSA/releases and download either windows exe or mac app of latest bossac. unzip.  Go to Step 12.
-
-For Linux users it is best to build a copy of bossac locally - 
-clone the Adafruit Repostitory to somewhere on your local machine.
-```
-git clone https://github.com/adafruit/BOSSA.git
-change to the arduino branch
-git checkout arduino
-```
-Follow the instructions to build bossac in README.md or at https://github.com/adafruit/BOSSA/tree/arduino.
-
-7. Replace the binary at ".../Library/Arduino15/packages/arduino/tools/bossac/1.7.0/bossac" or "...\AppData\Local\Arduino15\packages\arduino\tools\bossac\1.7.0\bossac"
-8. On Windows 7 you will also need to install the updated serial driver, download https://github.com/adafruit/Adafruit_Windows_Drivers/archive/master.zip to get all the drivers, and point the Device Manager to the unzipped folder. It isn't signed, so just approve the installation manually.
-13. That's it!
-
 ## Bugs or Issues
 
-## Known Issues for SAMD51:
 * AREF must be tied to 3.3V for dac to work. This is a bug in the SAMD51 silicon.
 * USB host mode doesn't work yet
