   * **Stable**: (default) stable patchsets marked with `eportal` label on [the patch server](https://patches.kernelcare.com/).
   * **Testing**: all patchsets available on [the patch server](https://patches.kernelcare.com/).
+  * **Unstable**: patches from early-access feed (not recommended).
 
 Every 10 minutes ePortal checks for new patches on the main patch server. If a new patch is available, it is uploaded to the ePortal server. Note: it is uploaded but is not deployed. The patch availability time is considered starting from the moment a new patch appears on the ePortal, and that time is taken into account in `Deploy after X hours` option. So, if a user sets `Deploy after X hours = 10`, the patch will be deployed to the feed 10 hours after it has been downloaded to the ePortal server.
