+## [1.2.2] - 2018-05-27
+
+Firmware: 8.2.**5** [[release](https://github.com/UltimateHackingKeyboard/firmware/releases/tag/v8.2.5)] | Device Protocol: 4.3.**1** | User Config: 4.0.**1** | Hardware Config: 1.0.0
+
+- Offer recovery for bricked right keyboard halfs.
+- Detect when the hardware configuration of a device is invalid and display a notification.
+- Check if the keyboard is in factory reset mode and if so, display a relevant instruction.
+- Only allow ASCII characters in type text macro actions.
+- Allow uploading the same file multiple times in a row.
+- Only send auto update notification when the user initiates the update.
+- Update the firmware versions on the firmware update page right after firmware updates.
+- Add a lot of useful instructions to the firmware page to help users update the firmware.
+- Add the operating system and initial device list to the firmware update log.
+- Add copy to clipboard button to the top right corner of the firmware update terminal widget.
+
+## [1.2.1] - 2018-05-12
+
+Firmware: 8.2.**2** [[release](https://github.com/UltimateHackingKeyboard/firmware/releases/tag/v8.2.2)] | Device Protocol: 4.3.0 | User Config: 4.0.**1** | Hardware Config: 1.0.0
+
+- Match for the new USB usage page and usage number. This is critical for UHKs flashed with firmware >=8.2.2 to be recognized by Agent on OSX.
+- Make the config serializer handle long media macro actions. `USERCONFIG:PATCH`
+- Add note on the macro page explaining that the macro engine of the firmware is not ready yet.
+- Add an example to the scancode tooltip to better explain users how to invoke non-US characters.
+
+## [1.2.0] - 2018-04-20

+
+- Tweak the default mouse speed. This was necessary because the last firmware version adjusted speed multipliers. The mouse speed can be reset via the "Reset speeds to default" button of the "Mouse speed" page.
+- Make the newly added switch-keymap.js script utilize the new UsbCommandId_SwitchKeymap, allowing for programmatic keymap switching. `DEVICEPROTOCOL:MINOR`
+
+## [1.1.5] - 2018-04-10
+
+Firmware: 8.1.5 [[release](https://github.com/UltimateHackingKeyboard/firmware/releases/tag/v8.1.5)] | Device Protocol: 4.2.0 | User Config: 4.0.0 | Hardware Config: 1.0.0
+
+- Don't allow to run multiple instances of Agent at the same time, but rather focus the already existing Agent window.
+
+## [1.1.4] - 2018-04-09

+- Handle privilege escalation gracefully on Linux even without PolicyKit.
+- Fix application icon path.
+- Replace application icon with a diagonal gradient based icon that should look better on desktop.
+- Make saving the configuration more robust, and add a configuration recovery screen.
+- Reposition the ISO key in the scancode list.

 Agent is the configuration application of the [Ultimate Hacking Keyboard](https://ultimatehackingkeyboard.com/).
 
-[Give it a whirl!](http://ultimatehackingkeyboard.github.io/agent/)

-## Two builds to rule them all
-
-It's worth mentioning that Agent has two builds.
-
-The **electron build** is the desktop application which is meant to be used if you have an actual UHK at hand. It starts with an opening screen which detects your UHK. You cannot get past this screen without connecting a UHK via USB.
-
-The **web build** is meant to be used for demonstration purposes, so people who don't yet own a UHK can get a feel of Agent and its capabilities in their browser. Eventually, WebUSB support will be added to the web build, making it able to communicate with the UHK. Given the sandboxed nature of browsers, the web build will always lack features that the electron build offers, so this won't make the electron build obsolete.
-
-The two builds share code as much as possible.
+* Try out the [web build of Agent](http://ultimatehackingkeyboard.github.io/agent/) in your browser. This is meant to be used for demonstration purposes.
+* Download the [desktop build of Agent](https://github.com/UltimateHackingKeyboard/agent/releases) from our releases page. Use this if you have an actual UHK at hand, or else you won't get past the opening screen!
