-_Upgrading from v2.x: the [migration guide](https://four.htmx.org/migration-guide-htmx-4/) lists changes for v4. For this package, the `HX-Trigger` and `HX-Trigger-Name` headers are marked obsolete. They are replaced by `HX-Source`, which provides the triggering tag name and `id` attribute. The `HX-Prompt` header has also been marked as obsolete, as the `hx-prompt` attribute which generated its content has been removed._
