@@ -5,6 +5,49 @@ All notable changes to this project will be documented in this file.
 The format is loosely based on [Keep a Changelog](http://keepachangelog.com/en/1.0.0/)
 and this project adheres to the [UHK Versioning](VERSIONING.md) conventions.

+## [8.4.0] - 2018-07-24
+
+Device Protocol: 4.**4.0** | Module Protocol: 4.0.0 | User Config: 4.1.0 | Hardware Config: 1.0.0
+
+- Rewrite the key debouncer and set the press and release timeouts to 50ms.
+- Add hardcoded test keymap.
+- Make debounce timeouts configurable via USB. `DEVICEPROTOCOL:MINOR`
+- Make the hardcoded test keymap able to trigger via USB. `DEVICEPROTOCOL:MINOR`
+- Allow the USB stack test mode to be activated via USB. `DEVICEPROTOCOL:MINOR`
+
+## [8.3.3] - 2018-07-03
+
+Device Protocol: 4.3.1 | Module Protocol: 4.0.0 | User Config: 4.1.0 | Hardware Config: 1.0.0
+
+- Implement the macro engine.
+- Fix the nondeterministic bug that made USB hang.
+- Restore the Windows related commits of firmware 8.3.1 because the USB hang bug has been fixed.
+- Restore debouncing to 100ms until it gets really fixed.
+
+## [8.3.2] - 2018-06-27
+
+Device Protocol: 4.3.1 | Module Protocol: 4.0.0 | User Config: 4.1.0 | Hardware Config: 1.0.0
+
+- Make the debouncer debounce not only on key presses but also on key releases, and change the debounce interval from 100ms to the suggested 5ms of MX switches.
+- Revert the Windows related commits of firmware 8.3.1 because they introduced a nondeterministic bug that made USB hang.
+- Add base layer key mappings for the left and right add-ons for testing purposes.
+
+## [8.3.1] - 2018-06-07
+
+Device Protocol: 4.3.1 | Module Protocol: 4.0.0 | User Config: 4.1.0 | Hardware Config: 1.0.0
+
+- Fix media key repetition bug on Windows.
+- Fix bug that made Windows unable to sleep when the UHK was plugged in.
+- Fix bug that made Chrome Remote Desktop blocked from interacting on Windows.
+- Fix bug that made locked layers not release. This bug was introduced in the previous release.
+
+## [8.3.0] - 2018-06-03
+
+Device Protocol: 4.3.1 | Module Protocol: 4.0.0 | User Config: 4.**1.0** | Hardware Config: 1.0.0
+
+- Make the config parser handle switch layer actions with hold on double tap disabled. `USERCONFIG:MINOR`
+- Set key debounce timeout from 80ms to 100ms. This should further reduce key chattering.
+
