Hi,
no, there were no changes in the licenses itself,
only the separate buy options for the Domain and Tools licenses were removed,
see here about that:
http://krpano.com/news/#2010-05-06
krpano 1.0.8.10
and in the current version of the tools the droplets are embedding the viewer license now into the generated swf/js files by default,
and therefore the viewer license (krpano.license) must be also in the tools folder,
best regards,
Klaus
