Overall | Fixes and improvements (Sep 2026)

Minor releases introduce new features and improvements. Check out what’s new!

📘
Delivery API | If a translation value is empty during publish (for example in the Filter Templates), we will use your default language value as the fallback value instead of leaving it empy. This is only for the Delivery API. Our Backend API will still have an empty value. From now on, Tweakwise also will suggest English as default language (instead of Dutch) and will configure this automatically for new insances.

Backend API | Added validation on categoryIds: they can not exceed the Javascript safe integer range of '9007199254740991' to prevent issues with frontend functionality.
Delivery API | We’ve made a small change related to how facet suggestions are ordered in the response. Overall the ordering of facet suggestions remain the same, but for edge cases where suggestions are otherwise tied we now use value length as an additional tie-breaker (shortest first) followed by alphabetical order. For example, when searching for mar, mars appears before marble, while equally long values such as marble and market are ordered alphabetically. This makes results consistent and gives us a clear explanation for their order.

Tweakwise App

Tweakwise App | The state of list overview pages in Tweakwise App now remain in tact after a save or cancel action. Returning from edit pages now brings back search, filters, sort, and page as they were.
Tweakwise App | We fixed a bug where the bookmark section in the navigation menu only accepted one bookmark. Bookmarks now support multiple items, as intended.
Tweakwise App | We fixed a bug where a direct link to a category landingpage did not work.
Tweakwise App | Items with grouped products now show their related products consistently in the App.
Tweakwise App | Opening builder templates, filter template and related configuration pages no longer unexpectedly ends the user session in some situations.
Tweakwise App | Due to an incorrect lookup path because of module routings, there was an issue with the attribute lookup in the old Recommendations module which resulted in not being able to select attributes. This has been solved.
Tweakwise App | Fixed issue blocking creation and saving of new filter templates when adding one or multiple filters, related to the translations of 'show more' and 'show less' texts.
Tweakwise App | Fixed copy actions so they copy the key without sending you to another instance.
Tweakwise App | We fixed a performance issue in the Google Analytics 4 module. As the first load can still be slow, after that the loading should be much faster.
Tweakwise App | The Stoplist overlap (in Filler Words) now shows attribute names more clearly instead of IDs, so customers can understand what overlaps at a glance.

Demoshop

Demoshop | We fixed a bug regarding the login-flow in Tweakwise Demoshop. Signing in or out now keeps users on their current Demoshop page and instance whenever possible.
Demoshop | Fixed the search flow so a new search no longer blows up with a header-too-large error by decreasing the cookie duration to a month instead of a year.
Demoshop | earch no longer gets stuck or leaves page blank after searching with empty result and returning.
Demoshop | Apparently, the profileKey value got cleared after pressing save and became useless for that reason. Now it works as expected.
Demoshop | The Toolbox now does show a neat indicator that it has more 'tools' to offer when shown in minimized view. Hidden tools are now easier to discover, so users can find more options without hunting for them.
