 ⚠️ This release introduces a breaking change. ⚠️
@@ -13,7 +48,27 @@ Please read this release notes carefully before upgrading.
 
 Docker-related files were moved to the `docker` directory and some of them were renamed. Before upgrading, study carefully changes in the `docker/docker-compose.yml` file and update your docker-compose file accordingly, so it uses the new files and commands. Copying `docker/docker-compose.yml` blindly may lead to errors.
 
-No volumes were removed or renamed, so with a proper docker-compose file, you should be able to upgrade without any issues. To make it easier comparing your existing docker-compose file with the new one, you may use https://www.diffchecker.com/.

 Although `docker-compose.production.yml` was added, it's not being used by default. It's just an example of how to configure Dawarich for production. The default `docker-compose.yml` file is still recommended for running the app.
