## Deprecations
The `pre-deploy` plugin trigger is deprecated as of `0.34.4`. It is currently invoked during the `post-release-builder` plugin trigger, where image mutation is heavily discouraged. Users should instead move any trigger usage to the `pre-release-builder` plugin trigger. The `pre-deploy` plugin trigger will be removed in a future release.
