This version does not include new functions or features. This is a version that modifies the current add-in functionality. Interface consistency and some background algorithms have been improved.
If you have purchased an Annual add-in license, you can install it automatically. If you have a Perpetual license, you can also install this add-in as it is a 1.x version. Switching from 1.0 and 1.1 is free. The difference will occur when upgrade to a 2.x version (in the future).
