For example,

Hi,

Thank you for writing to us.

The current patch available for Zimbra 9(Zextras Build) is Patch 25.

Though Zimbra 9(Network edition) has released patches 26 & 27.

So if you are using Zimbra 9(Zextras Build) we would request you wait until we release an official build with the latest patch

Many of our users are also concerned just like you, so we assure you that we are working to release the build with the latest patch
considering its importance.

 

Thanks and regards,
