Version 184.108.40.206 of our AssureSign solution for Dynamics 365, and CRM 2015 and 2016 is now available for download here.
This release is a bug-fix only release, and addresses validation errors that can occur when parameters are not required. Previously, submissions could fail to occur when parameters exist on a template that are not required and a regular expression string exists on the parameter. With this fix, zero length parameters will not be tested against a regular expression validator if they are not required.
If you do not have templates configured with unrequired parameters that have regular expression validation in place, installation of this version is not required.
