 # Adafruit nRF52 Arduino Core Changelog
 
-## 0.22.0 - WIP
+## 0.22.0 - 2021.05.19
 
 This version implement comprehensive LESC and Legacy pairing using dynamic & static Passkey.
 
 - Support static passkey (Legacy only)
 - Support LESC on nRF52840 using hardware-accelerated ARM CryptoCell CC310 provided by [Adafruit_nRFCypto](https://github.com/adafruit/Adafruit_nRFCrypto). The library is included as submodule and released together with the BSP.
 - Rework bonding mechanism to use IRK for peer finding. It is advisable to run `clearbonds` example to clean up bond files of previous version
+- Add setPins() to SPI class
+- Fix bug that with saving cccd data
+- Add more pinMode type: INPUT_SENSE_HIGH, INPUT_SENSE_LOW, OUTPUT_S0S1 etc ...
+- Optimize mutex usage in UART
+- Add analogReadVDD() function
+- Update itoa.c for compiling with c++17
+- Fix BLEBeacon endian for major and minor
+- Fix compiling with MIDI v5, adding stub for BLEMidi's beginTransmission() and endTransmission()
+- Update BSP core to work with Adafruit_TinyUSB_Arduino version 1.0.0

 - Bluefruit::requestPairing() is removed, please use the BLEConnection::requestPairing() instead
 - Bluefruit::connPaired() is removed, please use BLEConnection::secure() instead
 - Default Device name is USB_PRODUCT if available e.g CLUE, Circuit Playground Bluefruit, Feather nRF52840 Express etc ...
+- Rename function for consistency BLEPeriph's setSlaveLatency() to setConnSlaveLatency()

 - Added BLEConnection::secured() to check if the connection is secured/encrypted
 - Added BLEConnection::bonded() to check if we store Longterm Key with current peer
 - Removed BLEConnection:paried(), user should either use secured() or bonded() depending on the context
-- If bonded, getPeerAddr() will return peer public address instead of random address. 
+- If bonded, getPeerAddr() will return peer public address instead of random address.
+- Rename getConnSupervisionTimeout() to getSupervisionTimeout()
 
 **New Example Sketches**
 
 - **pairing_pin** to use static PIN for peripheral role
 - **pairing_passkey** to use dyanmic Passkey for pairing. On Arcada compatible device such as `CLUE` or `Circuit Playground Bluefruit`, TFT display will also be used to display passkey.
 - **cental_pairing** similar to pairing_passkey but for nRF running central role
 - **ancs_arcada** for displaying ancs on arcada such CLUE and/or CPB.
+- **arduino_science_journal** add sketch to run with Arduino Science Journal
+- **adv_AdafruitColor** example to tie Arduino to CircuitPython BLE color
