The changes between v4.20 and v4.30 consist of the following new features:
Added a Single Line Enter Key dialog option, and an option for an HTML Enter Key dialog, for the Professional Edition only.
Added a "disable UNREGISTER" option, by request.
Added a default website/buynow URL for use when no certificate is active.
You no longer have to specify another expiration type in order to get the expiration message when using expire-by-minutes.
The client/server Network Licensing system no longer requires UDP/IP access to verify the server when you've specified a server address in the INI file, which should allow client/server licensing to work over the Internet more reliably.
Fixed a bug when using compressed resources and running in a Win/9X environment. A second run in that situation resulted in a CRC error.
There were also bug-fixes and other changes. Refer to Revision History for the list.
As always, please let us know if you have any questions, or run into any problems with it.
