Zextra 2.2.5 and Zimbra 8.6 - The ZAL version downloaded is too old

This morning I downloaded the latest version of Zextras 2.2.5 to upgrade my previous 2.2.4 installation.

Running Centos 7 64bit and Zimbra Open Source Version: 8.6.0_GA_1200 (i.e. patch 7).

Upon issuing the ./install.sh all command I received the following error message:

Downloading the ZAL library. It might take a few minutes ...
** GET http://openzal.org/1.10/zal-1.10-8.6.0.jar ==> 301 Moved Permanently
** GET http://openzal.org/1.10/zal-1.10.5-8.6.0.jar ==> 200 OK (1s)

The ZAL version downloaded by the ZeXtras Installer is too old
and it's not compatible with this release of ZeXtras Suite:
please check the ZeXtras Forums at http://forums.zextras.com for more info.

Any suggestions?
