+Adds a new `BACKSTAGE_CLI_BUILD_PARELLEL` environment variable to control
+parallelism for some build steps.
+
+This is useful in CI to help avoid out of memory issues when using `terser`. The
+`BACKSTAGE_CLI_BUILD_PARELLEL` environment variable can be set to
+`true | false | [integer]` to override the default behaviour. See
+[terser-webpack-plugin](https://github.com/webpack-contrib/terser-webpack-plugin#parallel)
+for more details.
