# Version 2026-33

## Release date

August 24, 2026

## Studies

This release focuses on Studies: a redesigned participant survey, support for randomized split-face designs, and a long list of study-design and participant-experience fixes. Learn more: [Studies](/haut.ai/haut.ai-features/studies.md).

### Redesigned participant survey

The survey a participant fills in during a study has been redesigned, with the photo capture task updated to match. Learn more: [Study Interface for Participants](/haut.ai/haut.ai-features/studies/participants-point-of-view.md).

### Split-face studies with per-side arms

A study arm can now be assigned per side of the face, so you can run randomized split-face designs where each participant receives a different product on the left and the right side. Side assignment is randomized per participant, and results can be compared by side. Learn more: [Create New Study](/haut.ai/haut.ai-features/studies/step-1.md).

### Desktop install walkthrough

Participants on desktop Safari now get an **Add to Dock** walkthrough during onboarding, instead of being sent straight to the dashboard with no way to install the app. Add-to-home-screen guidance was updated to match. Learn more: [Study Interface for Participants](/haut.ai/haut.ai-features/studies/participants-point-of-view.md).

### Study design improvements

* **Stage offset can now be `0`**, so stages can sit consecutively. The previous five-minute minimum shifted every following stage and could accumulate into hours of drift across a long study.
* The offset field no longer accepts negative values.
* The **Add stages** dialog was redesigned.
* The **Objectives** and **Study Protocol** windows can now be resized, which makes long text easier to work with.
* Stages stay sorted by start date.
* **Number** and **Age** survey questions no longer accept decimal values.
* The Fitzpatrick question titles and answer options now match the wording in the reference documentation.
* Adding a photo task that a participant has already used now warns you, as it already did for survey tasks.
* Studies with many stages load their participant list considerably faster, and the participants table is paginated for large studies.

### Fixes

* The **Schedule** view now shows a month heading for relative stages.
* Stage status now updates immediately after an edit, without a page reload.
* Submissions and participant history now update as each task is completed, rather than only once every task in the stage is finished.
* Survey skip logic now works while answering questions.
* A participant who has completed part of a study now sees **Resume** instead of **Get started**.
* Participants with the **New** status can now be discontinued.
* The participant issue status is now displayed.
* Secondary participant screens and the pre-capture guide now wrap correctly on desktop.
* Tooltips now appear above modal windows instead of behind them.
* Conflicting changes to a study now show a clear message instead of an unhandled error.
* Opening an expired QR code now shows a proper error state.
* The next-month button in the calendar is now clickable across its whole area.
* A **Contact Us** option is now shown after a participant exits a study manually.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.saas.haut.ai/haut.ai/releases/changelog/version-2026-33.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
