    In [GitLab 14.3](https://gitlab.com/gitlab-org/gitlab-runner/-/merge_requests/3074), we added a configuration setting in the GitLab Runner `config.toml` file. This setting, [`[runners.ssh.disable_strict_host_key_checking]`](https://docs.gitlab.com/runner/executors/ssh.html#security), controls whether or not to use strict host key checking with the SSH executor.

    In GitLab 15.0 and later, the default value for this configuration option will change from `true` to `false`. This means that strict host key checking will be enforced when using the GitLab Runner SSH executor.
