 # Changelog
 All notable changes to my userspace will be documented in this file.
 
+## [0.4.0] - 2021-10-05
+
+### Added
+- Introduced new keycode KV_VER to output the version of QMK. Thanks to drashna for this. 
+
+### Changed
+- Updated keymaps to use underscores instead of KC_TRNS as it was getting hard to read for my tired eyes. 
+- Updated readmes on my preferred layouts.
+
 ## [0.3.0] - 2020-02-02
 ### Changed
 - Added the `_CL` layer to all the boards for access to `EEP_RST` and `RESET` keycodes. This was done primarily to avoid triggering `RESET` accidentally.
