---

3.3.0

January 28, 2022

• Intent survey. We asked users at the start and end of the interview what they intended to do next e.g. self care or go to the hospital. This means that now we can track the impact of current and future Symptom Checker features against user intent.
• reCAPTCHA improvements. We’ve added reCAPTCHA to the core product so that it can be used for additional protection against bots in instances. 
• Minor bugs fixed:

• • • Evidence level not displaying correctly in conditions sidebar panel.
    • Reversed bolding and inconsistent capitalisation in the symptom search autocomplete feature.
    • Age URL param accepting any value. URL params are used to repopulate risk factors like age so that the user does not need to fill them out if they’ve provided them elsewhere in the application.
    • Sidebar error that showed in the wrong place - at the top rather than above the ‘call to action’.

---

3.2.0

January 4, 2022

• New language: Romanian. Symptom Checker is now available in 16 languages.
• Speed up configuration. Removed screen editor and replaced with JSON file. This should significantly speed up configuration and testing of new instances, as configuration will now be done once, not separately for every language.
• Backend refactored. In this release we've completely rebuilt our old Healthform backend, essentially creating a new one. This included removing a lot of unnecessary code, improving the code we need, updating Django and other critical dependencies, increasing the test coverage and improving documentation.
• Improved analytics. Further improvements to support ‘new analytics’. This included adding an app version to each event, changes to the screen logic which made it easier to see what happened on what page, and new events for the "Calendar" and "Add info" actions.
• Monitoring improvements. Sentry integrated with test environments (not just prod) and started sending error logs to syserr/console.

Bugs fixed

• The offline notification is now also implemented in side panels. We’ve made sure that the offline message will not be displayed anymore in the main content area when a side panel is opened offline.
• Language selector dropdown and Search dropdown now in line with Navigation patterns. Selecting languages and symptoms is now smooth and easy when navigating with the keyboard.
• More texts now adapted to the Someone else mode. Missing strings have been added to Crowdin and to the app.
• Selecting the language currently selected resumes the interview. Now selecting the current language closes the language selector without losing progress.
• The calendar no longer closes after clicking an input field. Now the calendar switches to the tab that is dedicated to the input field.
• IFrame: side panels content now visible without scrolling up. We’ve implemented an automatic scroll.
• IFrame: no difference in height between the side panels and background questions.

---

3.1.3

November 17, 2021

General

• New languages: Czech, Italian, Portuguese, Slovak, Turkish and Ukrainian. Six new languages are now ready to use. Symptom Checker is now available in 15 languages.
• Improved translations. While working on new languages we corrected a lot of linguistic and grammatical errors, especially those concerning users that use Symptom Checker on behalf of someone else.

Bugs fixed

• The Medical Certification screen now contains accurate data. We’ve updated the current app version and release date as well as making sure it will always be up-to-date.

---

3.1.2

October 26, 2021

Bugs fixed

• Possible conditions no longer disappear. The list of diseases on the Results screen is now visible even if the internet connection drops out.
• “Select one answer in each row“ does not appear on mobile. Instead, we show another instruction, one that is more precise: “Select one answer for each statement“.
• The plural of nouns is now correct. Whether it's one star or five stars, one month or nine months; we've made sure that the plural forms for different nouns are correct in every language.
• The Arabic language version no longer contains untranslated words. We’ve noticed that the calendar widget contained some words in English, and fixed this.

---

3.1.1

General

• New languages: Dutch and French. Welkom en groeten! Bienvenue et salutations! Two more languages were thoroughly tested and are now ready for use.
• Article excerpts. Not sure what lactose intolerance or malaria is? Thanks to the open source content provided by NHS Choices and Medline Plus, users can now learn more about the conditions that may be causing their symptoms.

Bugs fixed

• User is now shown the correct element after closing the side panel. Instead of going back to the first element shown on the screen, the user now returns to seeing the element that caused the panel to appear.
• The header is now visible when Pediatrics features are disabled. In some cases, the application header was hidden. Now it’s visible at all times.
• The scroll is only visible when it's needed. We've fixed a number of issues that caused the scroll (both horizontal and vertical) to appear when it wasn't needed.
• IFrame now at the correct height. IFrame grows and shrinks accordingly when the content length changes (and the iFrame helper is configured accordingly).
• The calendar widget fits in the iFrame. We made sure that the calendar is visible, even when the iFrame is really small and the available space is very limited.

3.1.0

Analytics

• Safe internal analytics. Symptom Checker is now independent of third party analytics like Google Analytics or Amplitude. Every event (any interaction between a user and Symptom Checker) we track is now stored in our internal database. These events are cleared up, grouped, and displayed via our dashboards.
• More events and actions. Up until now, the ability to see how our users interacted with the Symptom Checker has been limited. We took this opportunity to update the list of data points we will track. Newly tracked events include search queries, transitions between screens (conversion funnel), and clicks on the body model.

Customizations

• Under the hood work. Configuration just got a bit easier. By leveraging the new technologies and a different approach to overriding defaults, Infermedica developers can now configure and ship new Symptom Checker setups faster and easier than ever before.
• Detailed design previews. Now you can see the complete set of screens before we hand them off to the developers. The tool we use for this is Figma.

Design

• New progress bar. Sometimes, due to the limited screen space, we'll hide the side navigation. However, we may still want to display interview progress. In these situations, we'll use a new progress bar, usually located above the question.
• 401 Not authorized screen. Authorization tokens are required to use our Symptom Checker on your website. In some cases, this token may be invalid or expired. Should that be the case, we'll now show a dedicated info screen.
• Health data processing consent. We’ve added consent for processing health data (second checkbox) to the Terms of Service screen.

Accessibility

• Focus. Now the focus indicator (the blue border around the focused element) is only visible when using a keyboard.
• Keyboard scroll. It doesn’t matter how long the page is, now you can scroll through it all using only a keyboard.

---

3.0.3

• The age confirmation window now displays the correct value (“Date of birth“ screen). The Age confirmation feature was previously missing when users selected an age via the calendar widget.

---

3.0.2

• Fixed problems entering the birth year. We noticed that sometimes it was not possible to enter a birth year. For instance, users would get stuck on "201" when they wanted to enter "2012". This is now fixed.

---

3.0.1

Technical

• Farewell Angular, welcome Vue.js. Symptom Checker (the front-end of it, to be precise) was recreated completely from scratch. From a user's perspective, this means better app performance and more frequent product updates.
• Faster, on both mobile and desktop. The app will now load faster and download less data, which is especially important on mobile devices. Our Lighthouse Performance score at the time of writing this was 95 out of 100.
• Brand new testing procedures. One of our top priorities is to ensure a smooth experience across all different types of browsers and devices. This is why we spent a tremendous amount of time working on our new testing procedures and scenarios, which are now ISO-13485 compliant. 

Design system

• New scalable design system. Our Symptom Checker is now built from small reusable blocks called components. Each component is tested before it can be used. This makes configuring the Symptom Checker’s easier than ever before.
• 200+ components. Our design system consists of 201 different components, including both simple ones, like button and input, and more complex ones like date picker or the mega menu.
• Design tokens. Each color, font size, and margin is a variable. There’s no room for randomness, everything is now consistent.

Design

• Design refresh. We took this opportunity to refresh the look of the Symptom Checker. The changes are subtle, but they make the app even more delightful and easy to use.
• Text aligned to left. Centered text is visually appealing, but less readable. That's why we decided to align everything to the left.
• Updated icons. Icons, along with other elements of our design system, have been standardized. Their size and color are now consistent throughout the app.
• Thoughtful use of color. Every color has its own meaning and evokes emotions. Because of this, we've decided to stop using colors when displaying icons (yes/no/don’t know) and condition probabilities (horizontal bars).
• Validation messages. We've created new tips and instructions (e.g. “Add at least one symptom“), making it much clearer what the app is asking us to do.
• Copy updates. We added new explanations (e.g., why Symptom Checker only allows you to choose between male and female) and edited a few texts (e.g. “Results“ are now “Possible conditions“).

Accessibility

• Accessibility features. We want to ensure that all Symptom Checker users (including people with disabilities) have equal access to information and functionality. From now on, every new feature will be designed and implemented with accessibility in mind. We will use Web Content Accessibility Guidelines (WCAG 2.1) as the benchmark.
• Accessibility testing. We continuously do both automated and manual testing. If a new feature does not pass testing, it will not be released to the public.
• Keyboard accessibility. We've made it possible to go through an entire interview using just the keyboard. The blue border shows which item is active at any given time.
• Better color contrast. According to the WebAIM Million report for 2021, 86.4 percent of home pages have low contrast text. We don’t want to be in this group. As such, we've decided to improve the contrast ratio between text and background, making it more readable for everyone.
• Increased text size. There’s a second way (besides contrast) to improve the legibility of the text – text size. We've increased the basic text size from 15 to 16 point text.
• Larger links and buttons. Have you ever struggled to click on a link because it was too small? Or clicked a link you didn’t intend to click? This problem should no longer occur in our Symptom Checker as we've decided to enlarge the interactive elements (such as links and buttons).
• Accessibility labels and descriptions. Not everyone can see what’s on the screen. Thus, we added labels and descriptions in code that can be used by screen readers and other assistive devices.

Legal

• ISO-13485 compliance. Our Symptom Checker is now in compliance with ISO-13485. This means that our software development process is validated and certified by an external organization (TÜV Nord).
• Medical Certification. The “CE Marking” screen has become the “Medical Certification” screen and is still available in the footer.
• Interview ID. A unique ID is assigned to each interview. Patients can use this ID to completely erase their interview data.

Other

• Additional URLs. Each side panel (e.g. Terms of Service or Privacy Policy) is now accessible via a unique link.
