 # Revision history for Arion
 
-## Next 0.2.0.0
+## 0.2.1.0 -- 2023-07-26
 
+### Added
+
+* `service.networks` now supports attribute set values with various options, thanks to @pedorich-n.
+* `docker-compose.volumes` can now be specified in multiple modules, thanks to @qaifshaikh.
+* `image.fakeRootCommands` for making modifications to the image that aren't "add a link farm".
+
+### Fixed
+
+* Regular maintenance fixes, including one by olebedev
+
+
+## 0.2.0.0 -- 2022-12-02
+
 ### BREAKING
 
 * The `project.name` option is now mandatory for projects that aren't deployed with the NixOS module.
-
 
 * 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.
