## New features and enhancements

Following are the new features and enhancements in this release.

### Support for
Red Hat Enterprise Linux 6.6 and CentOS 6.5 \& 6.6

Apigee Edge for Private Cloud supports Red Hat Enterprise Linux 6.6 (64-bit) and CentOS 6.5
\& 6.6 (64-bit).
This service pack is only required when installing on Red Hat 6.6 or CentOS 6.5/6.6.

**To apply this update and install with the newly supported operating
systems**:

1. Unzip Apigee Edge for Private Cloud - `apigee-edge-4.15.04.00.zip` or `apigee-edge-4.15.04.00-ws.zip`.  

   > [!NOTE]
   > **Note:** The \*ws.zip installer includes WebSocket support. Only use that installer if you're using WebSockets in production. That installer isn't recommended if you're not using WebSockets in production.

2. Unzip `apigee-edge-4.15.04.01-EL6.6.zip` into the same parent directory as the zip in step 1.
3. Run `patch-install.sh -d \<ApigeeEdgeInstallerDir\>`, where *\<ApigeeEdgeInstallerDir\>* is the location of Apigee Edge for Private Cloud installer directory, such as `apigee-edge-4.15.04.00`.
