1WARNING: Version 2.03 contains a change to the way that the "hostname" is 2determined. In previous versions, hostname was extracted by means of the 3hard coded call '/bin/hostname --long'. This is not implemented on all 4platforms and thus does not work for some installations of Crypt::License. 5 6This call has been replaced with a call to Sys::Hostname::hostname which is 7a part of the standard Perl distribution and is implemented on all known 8platforms. HOWEVER, the returned string is usually the SHORT version of 9the hostname. This may break some existing License certificates and require 10re-authorization / replacement of the keys when upgrading from versions 2.02 11and earlier. 12
