categories: ["Releases"]

Hugo `0.85.0` is on the smaller side of releases, but the main new thing it brings should be important to those who need it: Poll based watching the filesystem for changes.

Hugo uses [Fsnotify](https://github.com/fsnotify/fsnotify) to provide native file system notifications. This is still the default, but there may situations where this isn't working. The file may not support it (e.g. NFS), or you get the "too many open files" error and cannot or do not want to increase the `ulimit`. Enable polling by passing the `--poll` flag with an interval:

```bash
hugo server --poll 700ms
```

You can even do "long polling" by passing a long interval:

```bash
hugo server --poll 24h
```

This release represents **23 contributions by 6 contributors** to the main Hugo code base.[@bep](https://github.com/bep) leads the Hugo development with a significant amount of contributions, but also a big shoutout to [@raoulb](https://github.com/raoulb), [@jmooring](https://github.com/jmooring), and [@digitalcraftsman](https://github.com/digitalcraftsman) for their ongoing contributions.
