# 7. Experimental Features

This is a list of experimental features in CouchDB. They are included in a release because the development team is requesting feedback from the larger developer community. As such, please play around with these features and send us feedback, thanks!

Use at your own risk! Do not rely on these features for critical applications.

## 7.1. Content-Security-Policy (CSP) Header Support for /_utils (Fauxton)

This will just work with Fauxton. You can enable it in your config: you can enable the feature in general and change the default header that is sent for everything in /_utils.

>     [csp]
>     enable = true

Then restart CouchDB.

## 7.2. Nouveau Server (new Apache Lucene integration)

Enable nouveau in config and run the Java service.

>     [nouveau]
>     enable = true

Have fun!
