 - Detection of added/removed devices (e.g., when plugging or unplugging a
   keyboard). The devices are grabbed by `swhkd` if they match the `--device`
   parameters if present or if they are recognized as keyboard devices otherwise.
+- `Altgr` modifier added (https://github.com/waycrate/swhkd/pull/213).
 
 ### Changed
 
 - The project `Makefile` now builds the polkit policy file dynamically depending
   on the target installation directories.
+- Alt modifier no longer maps to the right aly key. It only maps to the left alt key. Right alt is referred to as Altgr (alt graph).
+- Tokio version bumped from 1.23.0 to 1.24.2 (https://github.com/waycrate/swhkd/pull/198).
 
 ### Fixed
 
 - Mouse cursors and other devices are no longer blocked when running `swhkd`.
 - Option prefixes on modifiers are now properly parsed. e.g., `~control` is now
   understood by `swhkd` as the `control` modifier with an option
+- Install mandocs in the correct locations.

-We use a server-client model to keep you safe. The daemon ( swhkd - privileged process ) communicates to the server ( swhks - running as non root user ) after checking for valid keybinds. Since the daemon is totally separate from the server, no other process can read your keystrokes. As for shell commands, you might be thinking that any program can send shell commands to the server and that's true!
