+The `versions:bump` command will no longer exit with a non-zero status if the version bump fails due to forbidden duplicate package installations. It will now also provide more information about how to troubleshoot such an error. The set of forbidden duplicates has also been expanded to include all `@backstage/*-app-api` packages.
