+### Introducing Bazel 7.2’s output service protocol
+
+One of the exciting new features in Bazel 7.2 is support for the Bazel Output Service which allows Bazel to lazily materialize outputs when you access them with normal filesystem operations. This allows you to maintain visibility to the entire output tree while still saving network bandwidth. 
+
+It can be enabled by providing command line flags `--experimental_remote_output_service` and `--experimental_remote_output_service_output_path_prefix`. In [this blog post](https://blog.bazel.build/2024/07/23/remote-output-service.html), we describe what the Bazel Output Service is, and why you’d want to use it.
