| # Experimental |
| |
| Some features and functionality in curl and libcurl are considered |
| **EXPERIMENTAL**. |
| |
| Experimental support in curl means: |
| |
| 1. Experimental features are provided to allow users to try them out and |
| provide feedback on functionality and API etc before they ship and get |
| "carved in stone". |
| 2. You must enable the feature when invoking configure as otherwise curl will |
| not be built with the feature present. |
| 3. We strongly advice against using this feature in production. |
| 4. **We reserve the right to change behavior** of the feature without sticking |
| to our API/ABI rules as we do for regular features, as long as it is marked |
| experimental. |
| 5. Experimental features are clearly marked so in documentation. Beware. |
| |
| ## Experimental features right now |
| |
| - The Hyper HTTP backend |
| - HTTP/3 support and options |
| - CURLSSLOPT_NATIVE_CA (No configure option, feature built in when supported) |
