Hi,
yes, simply overwriting might be possible, but if you have customized some config or template files, it might be better to extract the new tools to a new folder and then migrate the modified files and settings manually to the new version.
For updating existing projects the
krpano Update Tool could be used. This tool will update the viewer part of swf/js files.
The plugin files need to be updated manually, but in this case simply overwrite the old with the new ones.
Best regards,
Klaus
