Added the option to add "not congruent"(≇) and "not similar"(≁) symbols to the keypad.
Added accessibility support for the Drawing Question type including the toolbar, select and erase drawing marks.
Added three new events, which are fired when creating, editing and adding Items via the Activity Editor. These allow developers to add custom functionality, by listening for these events.
Changed the public methods: duplicateActivity(), setActivity() and setActivityItems() so that they now return false in the Item edit in Activity edit view. The new behaviour is clearer because it explicitly returns false instead of behaving unpredictably.
Changed the public methods: createItem(), duplicateItem(), editItem() so that they now return false in the Activity edit view. The new behaviour is clearer because it explicitly returns false instead of behaving unpredictably.
Improved the public method safeToUnload(). If it's called in the Item edit in Activity edit view, it now checks whether there are unsaved changes in both the Activity edit view and the Item edit view. Previously, it only checked if there were unsaved changes in the Item edit view. This makes the safeToUnload() public method more reliable when used to check if the user has any unsaved changes.
Added the option to add "not congruent" (≇) and "not similar" (≁) symbols to the keypad.
Updated the template placeholder for Cloze math Question type to be more math specific.
Added the ability to navigate clickable links (that are enabled with click events) via keyboard controls, to allow keyboard-only users to access the links. See here for the full list of affected report types and event types.

Fixed a bug in which the native “exit fullscreen” button on iOS (specifically on iPads) completely covered the Assess player's hamburger menu.
Fixed a bug in the Scientific Calculator where the aria-label of the toggle to switch between "radians" and "degrees" would not be updated after clicking on it.
Fixed a bug where the Custom Question type does not have scorer JS provided. In this case, the Question should be launched as a non-validatable Question and automarkable should return false instead of null.
Fixed a bug with the Image Annotation Uploader, where a loaded image was deleted and the "changed" event wasn't being called.
Fixed a bug where the save:success event did not contain the Item data.

Improved accessibility for our Video Player. Now, the time slider constantly shows its aria attributes, and the captions menu is fully accessible.
Improved accessibility for the Response Masking Setting in the Multiple Choice Question Type. Now, more context has been added for screen reader users when masking or unmasking a response option.
Improved the MathJax accessibility processing for better cross browser support, particularly on IE11.
Improved accessibility by removing role="heading" from the drop responses area of the image drag and drop Question type. Screen readers will no longer announce the heading when navigating through the response areas.
Improved accessibility by updating aria-label text editor inputs for the longText and longTextV2 Question types, in order to avoid screen readers repeating the stimulus.
Improved JS canvas-based score bars accessibility across all UI report types (except sessions-list-by-item, session-detail-by-item, session-detail-by-question,last-score-by-item-by-user, live-activity-status-by-user,activity-summary-by-group,sessions-summary-by-group and item-scores-by-tag-by-user),

17th Jul 2019

Features

Assess API v2.94.0, Questions API v2.141.0, Author API v1.52.0, Question Editor API v3.67.0, Reports API v1.11.0

Added the aria-current attribute to the review screen Items, so screen readers will announce which Item you are currently on.
Added 'aria-hidden' attribute to the progress bar of an Activity, to avoid repetition since screen readers would read the same as in the Items count.
Added a new option to the Hotspot Question type. This enables users to customize the focus state color, by letting them choose the color individually or globally as a default. For the Safari browser, in order to retain normal keyboard navigation behaviour with this fix, you will need to adjust Safari settings.
Added a shortcut for the Math Keypad to allow users to enter a forward slash without it being converted to a fraction.
Multiple changes in Item editing within Activities:
- The message "Item successfully added" has been changed to: "Item successfully added to the Activity".
- The message "This item will be added to the activity on save" has been changed to: "This item will be added to the Activity on save".
- The message "Item successfully added to the Activity" now gets dismissed when the user changes to a different view. Previously, the message was being dismissed when the Item was changed, which caused the rest of the UI to shift upwards and this could be inconvenient for authors.
Updated the disabled state for the back and settings buttons in the Item edit view, to be consistent with the rest of the disabled Authoring UI elements.
Added a new option to the Hotspot Question type. This enables users to customize the focus state color, by letting them chose the color individually or globally as a default.
Improved keyboard and content accessibility of chart tooltips across all UI report types (except item-scores-by-tag-by-user, sessions-summary-by-group and activity-summary-by-group), in accordance with WCAG 2.1 guidelines:
- It is now possible to toggle chart tooltips using keyboard focus. This allows keyboard-only users to view the contents of the tooltips. Additionally, tooltips can now be read by screen readers.
- Tooltips will now remain visible if the cursor is positioned onto the tooltip. This allows the text inside the tooltip to be selected using the cursor.
- All visible chart tooltips can now be dismissed by pressing the Escape character key.

Fixed a bug that added double quotes to aria-labels in cloze text Question types.
Fixed a bug with the compass tool in the Drawing Question type. When the user changed the uploaded image width and height manually with the wrong ratio, the compass could not be moved to the edge of the drawing area.

Added a flag called "compareGrouping" to Math formula, Cloze Math and Cloze Math with Image. This flag forces equivLiteral away from its default state to recognise parenthesis and correctly support the commutative property of multiplication.

Bugfixes

Items API v1.94.0, Assess API v2.92.0, Questions API v2.139.0, Author API v1.50.0, Question Editor API v3.65.0, Annotations API v0.7.1

Fixed a bug that caused a legacy version of Questions API (v1) to be loaded when questionsApiVersion: 'latest' version was requested.
Added the attempt_status metadata to Items, so that each Item’s attempt state can be correctly rendered when using lazyload mode.
Fixed a bug that caused vertical_stretch to fail to render properly after the reset public method was called.
Fixed bug that caused the input of shorttext and plaintext to render pasted RTF content incorrectly.
Fixed various bugs with the ratings Question type, related to rich text rendering and the modal user interface.
Fixed a bug that allowed users to dismiss the modal window when they were informed that their time was over. Now, as intended, they cannot dismiss it and they must submit the test.
Fixed a bug, adding new behaviour where the system clears aria live text after a short interval, once a cloze association Question is no longer being interacted with, so that the aria live text isn't needlessly read out again when navigating with a keyboard.

Fixed a bug where the getLocation() public method returned a route with :widgetData instead of :data, which was inconsistent with previous versions.
Fixed a bug where the setItemTags() arguments were not correctly handled, leading to incorrect Tags being shown in the user interface.
Fixed a bug where malicious client side content could potentially be executed when loading from an Item bank. This would have occurred prior to the loading of our rich text editor, which normally handles the filtering and escaping of content. Now, this potential risk has been eliminated.
Fixed a bug where dragging a Question or Feature to the bottom or top of the screen didn't cause the page to scroll.
Fixed a bug with the height of LaTeX source input field, in order to avoid a scrollbar overlapping the text being displayed.
Fixed an issue where undo/redo in conditional attributes in Features did not work in certain cases.
Fixed a bug when navigating the assessment with a screen-reader. If the assessment had Annotations API initialized, users would navigate through highlight elements that were not yet active.

Fixed the way cross-domain iframe is served, it is now using requested version by server side determination. This allows better forward compatibility.
Fixed a bug where a test:pause event was unexpectedly triggered after a submit call.
Fixed a bug where some customized labelBundle values were being converted to lowercase. Now, multiple sentences and proper names will remain capitalized as configured.
Fixed a bug where the responsive region updated the wrong region settings, so that the right region did not appear when changing the window size to a medium or large viewport.
Fixed a bug where the flag button and calculator button weren’t showing tooltips when the user’s cursor was hovering over the button.
Fixed a bug so that only the vertical_stretch_option will be applied when both vertical_stretch_option and scrollable_option are both enabled at the same time in the Items region. This will prevent conflict between the two settings.
Fixed an issue with internationalization labels not applying to Image Highlight Question types.
Fixed an issue where opening the Calculator feature could cause the page position to jump to the top of the page.

SET sessions/template: Tightened validation of the session_id attribute. Various elements of the system assume it to be a UUID, which led to downstream processing error when it was not. The endpoint now rejects the payload upfront with an indication that the attribute needs to be fixed before continuing.

20th Jun 2018

Features

Items API v1.84.0, Assess API v2.79.0, Questions API v2.123.0, Author API v1.34.0, Data API v1.24.0

Dynamic data now supports the characters " and \. This means authors don't need to manually enter unnecessary backslash \ characters when authoring.
Added mapping for Events API to support LTS versioning.
Added support for caching inline public methods for Items API.
Changed the behaviour of the submit dialog which was showing the close button when the "limit_type": "hard" init option was enabled. It previously allowed users to go back to the assessment.
Added an invisible character for texthelp support in matchlist. this will help screen-reading software process the words on the page.
Added an option of splitting the js property in custom Questions to Question and scorer within one object.
Added a Feature exposing an itemlist:selection:changed public event (when in item_list mode and enable_selection is true), whenever the user selects/unselects an Item and also when a selection is cleared using the clearSelectedItems public method. This allows you to identify selected Items to act on with a "save" button. It also works with pagination.
Allow specifying search filters in the Item lookup tables for Activity edit.
Fixed bugs and improved the user experience for authors who use audio recording when creating the Audio Player simple Feature.
For the math keypad, LaTeX can now be added into dynamic data without any need for extra escaping. LaTeX used anywhere else still requires the  delineators. This allows authors to more easily input LaTeX since they don't need to add in extra escape characters.
If the following conditions are met:
- a URL is added into dynamic data,
- the URL's MIME type is an image,
- the init option config.item_edit.item.dynamic_image_tag is true,
then the URL will now automatically be converted into a HTML img element. This enables authors that are unfamiliar with HTML to embed images simply by pasting the URL.
GET sessions/responses: custom session metadata can now be retrieved in the response using the "include": ["sessions.session_metadata"] option, so the session metadata is conveniently available while processing the responses and score data.

Improved the stability of the audio recorder Question type on mobile devices.
Fixed a bug where entering double quotes into a math formula within the stimulus results in subsequent HTML not being rendered correctly.
Fixed a bug that caused auto-generated math content from being cleared when the formula input's focus was removed.
Provided a better description for formula Question types when these Question types are validated.

Infinite repeating decimals
Decimals with a trailing zero
Measure of angle
Singular ordinal fractions
Mixed numbers
Unary plus

Fixed a bug where an error fetching past events on subscriber initialisation would prevent receiving any future events.The API still reports the error in the console, records it in the LearnosityEvents.errors list and sends it to the errorListener if specified, but now continues to send subscribe requests to retrieve new events and deliver them to the application.
Fixed the messages reported on backend errors. Previously, raw backend error responses were reported verbatim in the console. An additional error message is now reported, if available, giving more context about what the error means for the API (e.g., fatal or not). This does not impact what gets recorded (i.e, the error only) in LearnosityEvents.errors nor sent to the errorListener.
Fixed a bug where requests denied with 4xx HTTP errors would be retried in a tight loop. This prevents overloading the backend with a lot of known-incorrect requests. As before, the request is passed to the caller's errorListener, allowing it to be informed about the issue and take further corrective action if needed.
Fixed an XSS vulnerability where inserting an HTML tag with any "on" event function causes said function to be executed.
SET /itembank/items/tags - fixed a bug where supplying the same Tag with different spacing within its type or name can trigger a 500 server error. It now treats the above scenario as two separate Tags.
GET /itembank/questions - fixed an issue where a non-string array of references or item_references would trigger a 500 server error. The request now returns a validation error instead.
GET /itembank/items - fixed an issue where a non-string array of references or questions.references would trigger a 500 server error. The request now returns a validation error instead.
