Overall | Fixes and improvements (Feb 2026)

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

API's

• Backend API | In our API endpoints for creating and updating categories, there was an issue with categoryId null being processed as categoryId 0. This issue has now been fixed.
• Delivery API | Fixed an issue where range sliders (like price) would disappear when a search in combination with the range selection returned no results. Before, if a user filtered for a specific range that had no matching products, the slider itself would vanish. This left customers stuck with no way to adjust their selection. Now, these filters will remain visible so users can adjust the range.

Tweakwise App

• Tweakwise App | Since the 'Instance switched' modal shown where you log into another instance in a new tab often obfuscated information you wanted to copy/read to use in the second tab, it has become movable so you can drag it out of the way. Meanwhile, we fixed a bug where you would end up on a 404 page when switching instances.
• Tweakwise App | Fixed a bug where your saved User Preferences would not keep consistent.
• Tweakwise App | In Item lookup field (for example in the builder Product component) when searching for a specific item, you can now also search by id rather than just the name.
• Tweakwise App | Similar to the A/B Testing module, there is now an Event Tag widget on the detail page of Builder templates showing the state of implementation of important events (SessionStart, Purchase, ItemClick, PageView).
• Tweakwise App | Fixed an issue where you could no longer see the name of the person who started a task in Tweakwise App > Connectivity. This fix will work only for new task starts. Old tasks will only show the identifier.
• Tweakwise App | We've improved performance of our publish tasks, with less long lasting spikes during the publish search algorithms step.
• Tweakwise App | Fixed an issue in the new filter templates module where attributes were not correctly validated through the Backend API. We resolved this (caching) issue, and added some extra information in the error message in case it will fail again. We also included an extra validation on ManualBackupSorting method that was yet present on the ManualBackupAlternativeSorting method.
• Tweakwise App | We fixed an issue where Builders would not show up as linked although they did have links.

Demoshop

• Demoshop | In order to enable better analytics and personalization opportunities in the debug environment, the Demoshop now tracks all Event Tag events. We have added page impressions, add to carts, add to wishlists and item clicks.
• Demoshop | We have implemented a fuzzy search for searching within facet values. This was done to help users get better results, for example the term "L'Oreal" could not be found if the search term was "lorea".

Tweakwise JS

• Search & Merchandising JS | We have fixed an issue where products.(mobile|tablet|desktop)View option to set the default products layout per viewport (grid or a list) would not work. This option now works regardless of using the ui.productsViewButton option.
