 - Campaign steps run in a container that does not run as root could fail on systems that do not map the running user ID to the container, most notably desktop Linux. This has been fixed: temporary files and workspaces mounted into the container now have sufficient permissions to allow the container user to execute the step. [#366](https://github.com/sourcegraph/src-cli/pull/366)
 - Executing campaigns on Windows would fail due to obscure `--cidfile` errors: namely, the temporary cidfile would not be removed before `docker run` was invoked. This has been fixed. [#368](https://github.com/sourcegraph/src-cli/pull/368)
 - Unresponsive containers started by `src campaign [apply|preview]` can now be killed by hitting Ctrl-C. Previously the signal wasn't properly forwarded to the process in the container. [#369](https://github.com/sourcegraph/src-cli/pull/369)
