@kfury77: Normal practice to insure Customer Loyalty is to offer upgrades to existing customers with a substantial discount (IMO 10% is a joke!). But Blumentals does the opposite and reward new customers with the discount. :(
As an example, I recently upgraded Prepros
https://prepros.io/ (another program I use) and they offered a 52% discount when upgrading from previous version.
Quoting kfury77: "Honestly, the new version is worth it for the big number of new features and improvements. Buying it will support the developers and remember that many more features and improvements are planned via free updates this year."
As @slashy mentioned earlier, similar list of promised features have been posted for previous releases. And several of those new features NEVER got added to the promised versions. So I'm no going to blindly trust a list of promised features..
I have been a registered WeBuilder user ever since version 2010. But I guess it's time to look for some alternative unless a better upgrade discount will be available soon. As I'm NEVER going to pay more for an upgrade than for a new version.
