+In addition to the [changelog](https://github.com/LGUG2Z/komorebi/releases/tag/v0.1.22) of new features and fixes,
+please note the following changes from `v0.1.21` to adjust your configuration files accordingly.
+
+## tl;dr
+
+The way windows are sized and drawn has been improved to remove the need to manually specify and remove invisible
+borders for applications that overflow them. If you use the active window border, the first time you launch `v0.1.22`
+you may end up with a _huge_ border due to these changes.
+
+`active_window_border_width` and `active_window_border_offset` have been renamed to `border_width` and `border_offset`
+as they now also apply outside the context of the active window border.
+
+```json
+{
+  "active_window_border": true,
+  "border_width": 8,
+  "border_offset": -1
+}
+```
+
+Users of the active window border should start from these settings and read the notes below before making further
+adjustments.
+
+## Changes to `active_window_border`, and window sizing:
+
+- The border no longer creates a second drop-shadow around the active window
+- Windows are now sized to fill the layout region entirely, ignoring window decorations such as drop shadows
+- Border offset now starts exactly at the paint edge of the window on all sides
+- Windows are sized such that the border offset and border width are taken into account
+
+## Recommended patterns
+
+### Gapless
+
+- Disable "transparency effects" Personalization > Colors
+- Set the following settings in `komorebi.json`:
+```json
+{
+  "default_workspace_padding": 0,
+  "default_container_padding": 0,
+  "border_offset": -1,
+  "border_width": 0
+}
+```
+
+### 1px border
+
+A 1px border is drawn around the window edge. Users may see a gap for a single pixel, if the system theme has a
+transparent edge - this is the windows themed edge, and is not present for all applications.
+
+```json
+  {
+  "border_offset": 0,
+  "border_width": 1
+}
+```

+# Troubleshooting
+
+## AutoHotKey executable not found
+
+If you try to start komorebi with AHK using `komorebic start --ahk`, and you have
+not installed AHK using `scoop`, you'll probably receive an error:
+
+```text
+Error: could not find autohotkey, please make sure it is installed before using the --ahk flag
+```
+
+Depending on how AHK is installed the executable on your system may have a
+different name. In order to account for this, you may set the `KOMOREBI_AHK_EXE`
+environment variable in your
+[PowerShell profile](https://learn.microsoft.com/en-us/powershell/module/microsoft.powershell.core/about/about_profiles?view=powershell-7.4)
+to match the name of the executable as it is found on your system.
+
+After setting `KOMOREBI_AHK_EXE` make sure to either reload your PowerShell
+profile or open a new terminal tab.
+
+## Komorebi is unresponsive when the display wakes from sleep
+
+This can happen in rare cases when your monitor state is not preserved after it
+wakes from sleep.
+
+### Problem
+
+Your hotkeys in _whkd_ work, but it feels as if _komorebi_ knows nothing about
+the previous state (you can't control previous windows, although newly launched ones
+can be manipulated as normal).
+
+### Solution
+
+Some monitors, such as the Samsung G8/G9 (LED, Neo, OLED) have an _adaptive
+sync_ or _variable refresh rate_ setting within the actual monitor OSD that can
+disrupt how the device is persisted in the _komorebi_ state following suspension.
+
+To fix this, please try to disable _Adaptive Sync_ or any other _VRR_ branded
+alias by referring to the manufacturer's documentation.
+
+!!! warning
+
+    Disabling VRR within Windows (e.g. _Nvidia Control Panel_) may work and can indeed
+    change the configuration you see within your monitor's OSD, but some monitors
+    will re-enable the setting regardless following suspension.
+
+### Reproducing
+
+Ensure _komorebi_ is in an operational state by executing `komorebic start` as
+normal.
+
+If _komorebi_ is already unresponsive, then please restart _komorebi_ first by
+running `komorebic stop` and `komorebic start`.
+
+1. **`komorebic state`**
+
+   ```json
+   {
+     "monitors": {
+       "elements": [
+         {
+           "id": 65537,
+           "name": "DISPLAY1",
+           "device": "SAM71AA",
+           "device_id": "SAM71AA-5&a1a3e88&0&UID24834",
+           "size": {
+             "left": 0,
+             "top": 0,
+             "right": 5120,
+             "bottom": 1440
+           }
+         }
+       ]
+     }
+   }
+   ```
+
+   This appears to be fine -- _komorebi_ is aware of the device and associated
+   window handles.
+
+2. **Let your display go to sleep.**
+
+   Simply turning the monitor off is not enough to reproduce the problem; you must
+   let Windows turn off the display itself.
+
+   To avoid waiting an eternity:
+
+   - _Control Panel_ -> _Hardware and Sound_ -> _Power Options_ -> _Edit Plan
+     Settings_
+
+     _Turn off the display: 1 minute_
+
+   Allow a minute for the display to reset, then once it actually shuts off
+   allow for any additional time as prompted by your monitor for the cycle to
+   complete.
+
+3. **Wake your display again** by pressing any key.
+
+   _komorebi_ should now be unresponsive.
+
+4. **`komorebic state`**
+
+   Don't stop _komorebi_ just yet.
+
+   Since it's unresponsive, you can open another shell instead to execute the above command.
+
+   ```json
+   {
+     "monitors": {
+       "elements": [
+         {
+           "id": 65537,
+           "name": "DISPLAY1",
+           "device": null,
+           "device_id": null
+         }
+       ]
+     }
+   }
+   ```
+
+   We can see the _komorebi_ state is no longer associated with the previous
+   device: `null`, suggesting an issue when the display resumes from a suspended
+   state.
