Subject sums it up. It seems like these variables should be encrypted in some way rather than plain text.
Hi,
Thank you for notifying us of this omission. We have now implemented a fix and sensitive variables will be encrypted in VariableNamespaces.xml in the next version.
Thanks! I appreciate that you have Staff monitoring this and generally these problems get resolved with a minimum of drama…one of the selling points I use internally so keep up the good work!
