 ## Release History
 
+- HEAD adds support for KR-920 (Korea 920 MHz) in the region selection menu.
+
 - [v2.5.0](https://github.com/mcci-catena/Arduino_Core_STM32/releases/tag/v2.5.0) enables the crystal controlled LSE clock, and uses it to run the RTC. Code was substantially refactored to move common code to common directories. Bug fixes.
 
 - [v2.4.0](https://github.com/mcci-catena/Arduino_Core_STM32/releases/tag/v2.4.0) Added support for new boards: 4617, 4618 and 4630. Serial interface configuration in `boards.template` has been updated with new option to use both USB Serial and Hardware Serial at same time.
 
 - [v2.3.0](https://github.com/mcci-catena/Arduino_Core_STM32/releases/tag/v2.3.0) corrects the handling of clocking in the various SLEEP/STOP/SSTANDBY modes. It also ensures that `.RamFunc` code is properly placed in RAM (initialzed when statics are initialized).
 
-- [v2.2.1](https://github.com/mcci-catena/Arduino_Core_STM32/releases/tag/v2.2.1) fixed the version number in `platform.txt`, and sets GPIO to reset state when deinitializing SPI, I2C and UARTs.
+- [v2.2.1](https://github.com/mcci-catena/Arduino_Core_STM32/releases/tag/v2.2.1) fixed the version number in `platform.txt`, and sets GPIO to reset state when de-initializing SPI, I2C and UARTs.
 
 - [v2.2.0](https://github.com/mcci-catena/Arduino_Core_STM32/releases/tag/v2.2.0) increases the serial buffer size to 256 and adds low-power changes for the Catena 4801.
