#### What's Changed

GitHub has previously recommended updating the major version of the
action when bumping the node version due to the possibility of breaking
changes with GitHub Enterprise versions potentially not having access to
the newest node versions yet, because of this we have bumped the release
major version to `v3.0.0` for the release of this action using node 20
