On June 21, 2012 MacroSystem US announced the release of Bogart 4.5c:
With the release of Bogart 4.5c, there will be a change in our base Operating Systems. These changes will be as follows:
1 - If you currently have a system running Pro Pack software, this will now change to the Gold Edition. This is a name change only. Your same license code for Pro Pack will work to activate the Gold Edition. You will then see Gold Edition indicated on your Main Menu just below the Bogart SE logo.
2 - If you currently have a system not running Pro Pack software, you will need to activate the Silver Edition. You will need a new license code to activate the Silver Edition. To obtain this code, contact your local dealer or send an email to firstname.lastname@example.org. Be sure to provide the serial number when making your request.
The main differences between Silver and Gold can be found here.
Full details on Gold and Silver Editions can be found here.
