### Issue

The latest published version of `@fastify/htmx` does not contain all the changes in `main`. While the current state in `main` might not be worthy of a `1.0` release, I still believe that adding a `0.5.0` release with the current state is helpful so that it can be tested out in the wild.

My current workaround is to point the `@fastify/htmx` dependency to a commit in my fork (see [`package.json`](https://github.com/janmonschke/liveqa-fastify-htmx/blob/25129e167bce14dcd2a2b4c1a1d55c10d4631bee/package.json#L34)) which is not ideal.
