 - [Streaming evaluation](https://zhaofengli.github.io/colmena/0.3/features/parallelism.html#parallel-evaluation-experimental) powered by [nix-eval-jobs](https://github.com/nix-community/nix-eval-jobs) is now available as an experimental feature (`--evaluator streaming`).
 - Colmena can now run on macOS to deploy to NixOS hosts using [remote building](https://zhaofengli.github.io/colmena/0.3/features/remote-builds.html).
 - It's now possible to configure output colorization via the CLI and environment variables. Colmena follows the [clicolors](https://bixense.com/clicolors) standard.
+- [A systemd unit](https://zhaofengli.github.io/colmena/0.3/features/keys.html#key-services) (`${name}-key.service`) is now created for each secret file deployed using `deployment.keys` ([#48](https://github.com/zhaofengli/colmena/issues/48)).
 - Node enumeration is now faster if you do not filter against tags with `--on @tag-name`.
 - The main deployment logic has been rewritten to be cleaner and easier to follow.
 - There are now [end-to-end tests](https://github.com/zhaofengli/colmena/tree/main/integration-tests) to ensure that the development branch is actually functional as a whole at all times.
