+## [8.1.5] - 2018-04-04
+
+Device Protocol: 4.2.0 | Module Protocol: 4.0.0 | User Config: 4.0.0 | Hardware Config: 1.0.0
+
+- Set key debounce timeout from 30ms to 60ms. This should eliminate key chattering.
+- Use the correct scancode for the menu key of the factory keymap.
+
+## [8.1.4] - 2018-03-05
+
+Device Protocol: 4.2.0 | Module Protocol: 4.0.0 | User Config: 4.0.0 | Hardware Config: 1.0.0
+
+- Set key debounce timeout from 20ms to 30ms. This should eliminate key chattering.
+- Set double tap lock layer timeout from 250ms to 150ms. This should minimize the chance of locking layers accidentally by double tapping their keys.
+
+## [8.1.3] - 2018-02-18
+
+Device Protocol: 4.2.0 | Module Protocol: 4.0.0 | User Config: 4.0.0 | Hardware Config: 1.0.0
+
+- Fix system keyboard descriptor, so it is byte-aligned.
+- Set key debounce timeout from 15ms to 20ms. This should at least reduce and hopefully eliminate key chattering.
+
+## [8.1.2] - 2018-02-13
+
+Device Protocol: 4.2.0 | Module Protocol: 4.0.0 | User Config: 4.0.0 | Hardware Config: 1.0.0
+
+- Detect Caps Lock USB state and light up the Caps Lock icon of the LED display accordingly.
+- Set key debounce timeout from 10ms to 15ms. This should at least reduce and hopefully eliminate key chattering.
+
+## [8.1.1] - 2018-02-11
+
+Device Protocol: 4.2.0 | Module Protocol: 4.0.0 | User Config: 4.0.0 | Hardware Config: 1.0.0
+
+- Lock layers every time when double-tapping their layer switcher keys, regardless of how many times the layer switcher key was tapped before.
+- Only lock layers via double-tapping if the second tap gets released within 100ms.
+
+## [8.1.0] - 2018-01-15
+
+Device Protocol: 4.**2**.0 | Module Protocol: 4.0.0 | User Config: 4.0.0 | Hardware Config: 1.0.0
+
+- Enable left-half watchdog in reinit mode which seems to prevent freezes.
+- Slow down main bus I2C baud rate to 30kHz when BusPal is on to make firmware transfer more robust.
+- Implement UsbCommandId_GetSlaveI2cErrors. `DEVICEPROTOCOL:MINOR`
+- Implement UsbCommandId_SetI2cBaudRate. `DEVICEPROTOCOL:MINOR`
+- Implement DevicePropertyId_CurrentKbootCommand. `DEVICEPROTOCOL:MINOR`
+- Implement DevicePropertyId_I2cMainBusBaudRate. `DEVICEPROTOCOL:MINOR`

 ## Building and flashing the firmware
 
-For the left keyboard half, make sure to power it via the right keyboard half (which must be powered via USB). Also connect the left keyboard half to your SEGGER J-Link USB debug probe (which must also be connected via USB). Then in KDS, click on *Run -> Run Configurations*, select *GDB SEGGER J-Link Debugging -> uhk-left release jlink*, and click on the *Debug* button.

-For the right keyboard half, flash [the bootloader](https://github.com/UltimateHackingKeyboard/bootloader) first. Then in KDS, click on *Run -> Run Configurations*, select *C/C++ Application -> uhk-right release blhost*, and click on the *Debug* button. Please note that this update method only works on Linux out of the box. On other operating systems, you have to execute the relevant commands of the [blhost-unix.sh](right/build/kds/blhost-unix.sh) script.
+For the right keyboard half, flash [the bootloader](https://github.com/UltimateHackingKeyboard/bootloader) first.
+
+At this point, you can flash the right firmware via USB from KDS. To achieve this, you must build [Agent](https://github.com/UltimateHackingKeyboard/agent) that is Git submodule of the this repo and located in the `lib/agent` directory.  Then in KDS, click on *Run -> Run Configurations*, select *C/C++ Application -> uhk60-right_release_kboot*, and click on the *Run* button.
+
+From this point on, you can upgrade the firmwares of both halves via USB by using the uhk60-left_release_kboot and uhk60-right_release_kboot run configurations. Alternatively, you can use your SEGGER J-Link probe.
