 ### BREAKING
 
-* The NixOS module now sets the default project name
-* The NixOS module now sets the default network name to the project name (commonly referred to as `<name>` in the option path)
+* The NixOS module now sets the default network name to the project name (commonly referred to as `<name>` in the option path).
+  If this is not desired, for instance if you need the projects to be on the same network, set `networks.default.name` in each of them.
+
+* The NixOS module now sets the default project name. You can still set your own value with the `project.name` option.
+  If you did not set one, docker compose heuristically determined the name to be `store`, so you may want to set `project.name = "store"` or prepare to rename the network manually.
+
 * The `project.name` option is now mandatory for projects that aren't deployed with the NixOS module.
 
 ### Removed
 
  - NixOS 20.09 support. Its docker-compose does not support the
    `networks.<name>.name` option, which is important in later versions.
+   A newer, bundled docker compose may work there, but for now the decision
+   is to drop this legacy version.
