* Added settings to change defaults in Project Settings.
* Added prompts to save previous Material/Layer if dirty when Material/Layer references are changed and when exiting the Editor Mode.
* Updated Copyright Notice.
* Rewrote all [documentation to be better and reflect the new version of the Landscape Material Tool](/assets-and-plugins/landscape-material-tool/how-to-use-5.4+.md).
  * This includes a [Quick Tutorial](/assets-and-plugins/landscape-material-tool/how-to-use-5.4+/quick-tutorial.md).

* When the Master Material or Material Instance is manually set, it now updates the material on the selected landscape too (optional).
  * Updating the Landscape Material through the normal Details Panel for the Landscape Actor now automatically updates the Editor Mode panel.
