If you are still using an earlier version of WebAcappella Fusion, this reminder applies to you. Since the release of SP4 on May 18, a loyalty discount has been available for upgrading to this major new version. It ends on Wednesday, June 17 at midnight. After that, the upgrade price will go up. In other words: you have one week left to upgrade to SP4 at the best price.
This deadline applies only to the upgrade of an existing license to SP4. If you purchase a new license, SP4 is already included by default—nothing changes for you.
What ends on June 17 at midnight
Since launch, your upgrade to SP4 has been eligible for a loyalty discount of 20% to 40%, depending on the version you currently own: the newer your license, the larger the discount. At midnight on June 17, this discount will expire. Upgrading to SP4 will still be possible after this date, but at the standard upgrade price.
In practical terms, waiting until June 18 to make the switch means paying more for the same update—up to €40 more for the Classic edition, up to €80 more for the Pro edition—for exactly the same Service Pack. The difference lies entirely in the timing, not in what you get.
SP4 has had time to mature
If you were waiting to make sure the version was stable before jumping in, that’s now a done deal. Three weeks after release, a large portion of Fusion users have already upgraded to SP4, and five hotfixes were deployed in the days that followed, in response to initial feedback from the community. The version is now proven.
SP4 does not affect your existing sites: they continue to function exactly as before. The new features are added to your toolkit; you use them when you decide to.
What SP4 unlocks
For reference, here are the key features of Service Pack 4. The complete overview of new features details each one.
- The completely redesigned responsive menu — no more of that long-standing friction point on mobile.
- E-commerce promotions — discounts on selected products, strikethrough prices, and badges, without touching the product pages.
- The Gradient Shape Divider — smooth transitions between sections, without a single line of CSS.
- Two new containers — Grid and FlexLayout, for modern, responsive layouts.
- Four new components — Table, Medallions, Accordion, and a redesigned Button.
- A library of ready-to-use sections that can be inserted with a single click.
Is updating the same as upgrading to SP4?
No — and that’s an important distinction. Updating the app is free for everyone and provides bug fixes, stability, and compatibility with the latest versions of macOS and Windows. Upgrading to SP4 involves unlocking new features via your license — only this part is eligible for the discount until June 17. We explain this process in detail in this article.
How to find out your price
The cost of your upgrade to SP4 depends on your current license (Classic or Pro) and the Service Pack you’re upgrading from: there is therefore no single price. The easiest way is to enter your license on the pricing calculator page, which will immediately display the exact amount, with the loyalty discount applied. As a rough guide, a new license costs €99 for the Classic edition and €199 for the Pro edition, including SP4.
Before updating, be sure to back up your projects. WebAcappella Fusion includes a manual restore point system (menu Project > Create a Restore Point)—create one before proceeding. And making a backup copy of the project folder never hurts.
Still on the fence? Now is the time: the version is proven, the new features are here, and the loyalty discount won’t be coming back. On June 18, the only thing that will change is the price.
