## 🐞 Bug Fixes

### Break back pressure in hidden subscribers

Jul 17, 2024 · [@dominiklohmann](https://github.com/dominiklohmann) · [#4399](https://github.com/tenzir/tenzir/pull/4399)

The `subscribe` operator no longer propagates back pressure to its corresponding `publish` operators when part of a pipeline that runs in the background, i.e., is not visible on the overview page on app.tenzir.com. An invisible subscriber should never be able to slow down a publisher.
