++################################
++### Upgrading 1.5.0 -> 1.6.0 ###
++################################
++
++phpCAS now requires an additional service base URL argument when constructing
++the client class, similar to other CAS client's serverName config. It accepts
++any argument of:
++
++1. A service base URL string. The service URL discovery will always use this
++   server name (protocol, hostname and port number) without using any external
++   host names.
++2. An array of service base URL strings. The service URL discovery will check
++   against this list before using the auto discovered base URL. If there is no
++   match, the first base URL in the array will be used as the default. This
++   option is helpful if your PHP website is accessible through multiple domains
++   without a canonical name, or through both HTTP and HTTPS.
++3. A class that implements CAS_ServiceBaseUrl_Interface. If you need to
++   customize the base URL discovery behavior, you can pass in a class that
++   implements the interface.
++
++For option 1 and 2, protocol, hostname and port should all appear without a
++trailing slash, e.g. http://example.org:8080. You can omit the default port for
++the protocol, which means use https://example.org instead of
++https://example.org:443 (if you use HTTPS).
++
++For security reasons, we no longer allow service base URL discovery without an
++allowed list check by default. For more information, refer to the security
++advisory.
++
++This version also changed the CURL User Agent string that phpCAS uses when
++sending validation requests to the CAS server. It will appear as phpCAS/1.6.0
++with the version number reflecting the library version.

++################################
++### Upgrading 1.5.0 -> 1.6.0 ###
++################################
++
++phpCAS now requires an additional service base URL argument when constructing
++the client class, similar to other CAS client's serverName config. It accepts
++any argument of:
++
++1. A service base URL string. The service URL discovery will always use this
++   server name (protocol, hostname and port number) without using any external
++   host names.
++2. An array of service base URL strings. The service URL discovery will check
++   against this list before using the auto discovered base URL. If there is no
++   match, the first base URL in the array will be used as the default. This
++   option is helpful if your PHP website is accessible through multiple domains
++   without a canonical name, or through both HTTP and HTTPS.
++3. A class that implements CAS_ServiceBaseUrl_Interface. If you need to
++   customize the base URL discovery behavior, you can pass in a class that
++   implements the interface.
++
++For option 1 and 2, protocol, hostname and port should all appear without a
++trailing slash, e.g. http://example.org:8080. You can omit the default port for
++the protocol, which means use https://example.org instead of
++https://example.org:443 (if you use HTTPS).
++
++For security reasons, we no longer allow service base URL discovery without an
++allowed list check by default. For more information, refer to the security
++advisory.
++
++This version also changed the CURL User Agent string that phpCAS uses when
++sending validation requests to the CAS server. It will appear as phpCAS/1.6.0
++with the version number reflecting the library version.
