Are you a developer?

ZAL supports any Zimbra release equal to or higher than 6.0.7. If a new Zimbra version is released, download the latest version of ZAL so that your extension will be immediately compatible.

Your ZAL-based extensions are autonomous from the ZAL included in Zextras Suite and Zimbra Network Edition.

You can use more than one ZAL-based extension on your Zimbra server. Each extension uses a dedicated instance of the library.
