OneDeck was developed by an environment artist, with a focus on making life easier for other environment artists. However, OneDeck can be helpful to a variety of Blender users.

OneDeck is currently supported for version 4.2 and 4.3. I will do my best to make sure it's always updated to the latest version of Blender, but there will usually be a delay from the official Blender release to the OneDeck release.

Under the "Updates" tab in the add-on preferences, you can check if your current version is up-to-date. If it isn't, you'll see a button that will redirect you to Blendermarket where you can download the latest version.
