+The PR will only be created if there is no open PR for the same branch, even if there is a newer version of Antora UI Spring.
+For example, if there is an open PR to update from version `v0.4.11` to `v0.4.12` and `v0.4.13` is released, the workflow won't open a new PR for `v0.4.13` if the previous one is not closed.
