Parse error when exception is triggered
Add support for version 3.0 of the CAS protocol.
alias dev-master to 1.3.x-dev

I think that's what it really is for the moment: the next 1.3.x
(development version). Aliasing this branch to 1.3.x-dev allows people
to install dev-master but keep a real version constraint (like ~1.3) and
be confident they're not going to get BC-breaks.
Update AuthenticationException.php

$_SERVER['SERVER_ADMIN'] might not always be set, especially if you are using nginx, instead of apache.

This produces a notice: 

PHP Notice: Undefined index: SERVER_ADMIN in \CAS\AuthenticationException.php on line 77

I added the following logic, 

if( isset($_SERVER['SERVER_ADMIN']) )
    return $_SERVER['SERVER_ADMIN'];
else
    return '';
