Hi Simon,
Yes, last year we were stuck on version 12.x for more than 12 months, and finally we've had breakthrough upon breakthrough this year

You do get free upgrades for one month, or for however long it takes for a major change to be released.
When you can no longer upgrade for free, you may purchase one year software maintenance for only $9.95. This covers all upgrades - major and minor - released within the next 12 months. And it is a great bargain

Please email sales at zipmagic dot co for the ordering instructions.
Of course, your existing version remains perpetually valid and active, if for any reason you decide not to upgrade.
- Simon King.
