30.06.2022 3.6.0

Added

  • Accessibility:
  • Claim Management: Ability to cancel a claim manually with iProovMe.cancelTransaction() which will emit the integration_cancelled error.
  • UI: Added support for right-to-left languages.
  • UI: Users can now choose their webcam in full screen with a new camera selection button.
  • UI: We've added a set of options for controlling overlay colours, styles, and the floating prompt:
    • floating_prompt_rounded_corners controls corners of floating prompt. Use false to remove border radius (default: true).
    • liveness_overlay_stroke_color controls color of the overlay in Liveness (default: null).

Changed

  • UI - accessibility: We've changed the default values for not_ready_tint_color and ready_tint_color to ensure a minimum contrast satisfying WCAG 2.1.
  • Title: We've removed the default title - by default no content will be shown. A custom_title can still be set in SDK options.

Removed

  • Removed failure_network_problem from iproov-en.json as its never used.

Fixed

  • In version 3.3.2 we added a user_cancelled feedback code for when the user cancels their transaction on their own while pressing the 'Esc' key. That was missed in the Changelog at the time so we're surfacing that now.
  • Fetch-retry was no longer retrying when failing, this has been fixed.
  • Fixed countdown timer display in Kiosk Mode.
  • Fixed the close_button not being sized correctly in Safari.

Enhancements

  • Disabled RSE while in Kiosk Mode.
  • Allow LA to function while in Kiosk Mode.

01.04.2022 3.5.3

Fixed

  • UI: We've fixed an issue where the reflection strength estimator hung indefinitely when end users moved out of frame.
  • UI: In kiosk mode, we've fixed an issue where instructions don't appear when enable_floating_prompt isn't enabled.

22.03.2022 3.5.2

Fixes

  • UI: We've fixed regressions introduced in 3.5.1 relating to logo and close_button. Sorry.
  • Native Bridge: We've fixed cases where native_bridge_options were not being passed to the native SDKs.

04.03.2022 3.5.1

Additions

  • UI: We've added a new presentation mode which places alignment instructions over the user's face.
    • This is called enable_floating_prompt; you can opt-in to this by setting it to true.
    • It defaults to false.
  • UI: We've added a new filter option which lets integrators specify different styles for the Canny face abstraction:
    • Available options are classic, shaded and vibrant.
    • The default is shaded.
  • We've added a few new accessibility oriented language strings:
    • close_button_aria provides ARIA text for the close button icon.
    • face_scan_aria provides ARIA text for our main UI, if it is tabbed into.
  • We've added prompt_text_color which will replace footer_text_color in an upcoming release. See deprecations.
  • We've changed iProovSupport.checkWithPermission() to also return tests and flags, just like .check() does.
  • When the Web SDK's <iproov-me> component is removed from the DOM:
    • we now clean up any open resources such as WebGL render loops and video feeds;
    • if this happens before an error or result event (i.e. before the user completes), the SDK now emits an error and invalidates the transaction with the error code integration_unloaded
  • We've added an integration_unloaded error code to handle the above unmounting case for our customers tracking.

Changes

  • UI: Our UI has been rewritten so that it's more accessible, and scales better according to browser settings.
    • This replaces our old SVG based UI and uses the latest cutting edge technologies, HTML and CSS.
  • Internal: Our team has started migration to TypeScript in order to reduce integration issues for our customers.

Fixes

  • UI: We've found and replaced the missing scan line in iOS 15.
  • Cameras: We've fixed an issue where cameras not providing a feed crashed the Web SDK.

Deprecations

  • The option footer_text_color is now deprecated, please use prompt_text_color instead.

01.02.2022 3.4.0

Fixed

  • UI - Fixed an issue where the UI scaled incorrectly when shifting between orientations and resizing the window
  • UI - We've reduced the "page jank" when resizing the UI, when the window resizes change or the phone rotates

Changes

  • UI - We've smoothed out the "move closer" prompt to avoid toggling between two UI states.
  • Timeouts - We now handle timeout logic in a much clearer way:
    • The SDK emits an error event with feedback code error_token_timeout if the user starts the iProov session too late.
    • As before, if the user starts iProoving but doesn't stream imagery in time, the SDK emits a failure event with the feedback code failure_user_timeout.
  • Error messaging and language - We've increased the level of detail, see iproov-en.json for the new strings:
    • When the SDK runs any of the following callbacks: error, cancelled, interrupted, permission_denied, no_camera or unsupported:
      • The language string mapping to the feedback event property is now displayed as the heading.
      • A new language string has been added for each feedback code, suffixed with _message.
      • Example: error_no_camera is the heading term, defaulting to "We couldn't find a camera connected to your device"
      • Example: error_no_camera_message is the text term displayed beneath the heading, defaulting to "A camera must be available to use iProov"
    • If your integration specifies language strings but doesn't implement the new _message suffix, then we fall back to the old behaviour:
      • Heading using the "error" language term, and text using the corresponding feedback code's language term.

Added

  • Genuine Presence Assurance - added reflection strength estimation capabilities
  • Language strings:
    • error_token_timeout and error_token_timeout_message when sessions don't start within 10 minutes of token create
    • iproov_ready_title to allow internationalisation of "Ready to iProov" on the ready callback
    • iproov_ready_button to allow internationalisation of "Scan face" for the ready callback button

14.01.2022 3.3.8

Fixed

  • Support - We've improved support logic where our partners embed the Web SDK into webpages which might lack the required feature policies to run properly.
  • client_error - We've fixed a large proportion, if not all, of video NotAllowedError and fullscreen related TypeError in browsers that use different user activation paradigms.
  • server_error - Some cases where tokens expired after 10 minutes were being classified as server_error. These are now correctly thrown as error_expired_token.

Internal changes

  • Start button - After the user clicks the start button, we now briefly set the start button innerHTML to the prompt_loading language term while the video starts.
  • Support checker - We've made a few changes that help give users a better experience:
    • Where possible in Liveness, we now check document.featurePolicy for accelerometer, gyroscope and magnetometer. If these aren't allowed, instead of starting the SDK and erroring, we now run the unsupported callback.
    • We no longer use the Permissions API to establish camera support due to its poor support and unreliable behaviour.

22.12.2021 3.3.7

Fixed

  • Native bridge - fixed an issue with possible interplay with Zone.js

09.12.2021 3.3.6

Fixed

  • Client errors - We've fixed some, if not all, instances of NotAllowedError occurring when we get a video stream.
  • WebGL - We now gracefully handle webglcontextlost events which might happen when devices are under high load.
  • Iframe Bridge + Native Bridge - We fixed a regression introduced in 3.3.5. Sorry about that.

26.11.2021 3.3.5

Fixed

  • Supported Devices - Block custom webview user agents where we can't test if supported.
  • Interrupted Event - If exiting fullscreen, handle when there's no video feed.
  • Unsupported video feeds - Further improve handling of very low resolutions.
  • Permission button - the grant button delay has been fixed

Internal Additions

  • Telemetry - Collects state of the SDK during various events, and in the case of incomplete transactions.
  • Socket.io dependency - We've upgraded our socket.io client dependency to version 4 to match the server.

10.11.2021 3.3.4

Fixed

  • a11y - Improve text to speech order while using some screen readers.
  • No Face Timeouts - Only start detecting faces when ready is clicked.
  • Error Handling - Ensure error messages are always present.

11.10.2021 3.3.3

Fixed

  • Safari fullscreen issues - Handle Safari 13-14.1 not reporting fullscreen enter/exit events correctly.
  • Safari permission issues - We fixed an issue where permission could be blocked on certain devices.
  • Progress event - Progress event returned messages weren't being localised.

Changes

  • Unsupported video feeds - Detect very low resolutions and attempt to use a different video device if possible.
  • Safari 15.0 desktop - Regrettably, this browser is now blocked until Apple releases a version that fixes various regressions.
  • Native Bridge - Inside iframes, iOS Native Bridge now works on iOS versions <= 14.0. Older versions are unsupported.
  • WebGL - THREE.js upgraded to 0.133.1.

17.08.2021 3.3.2

Fixed

  • Liveness - We have worked around instances where devices do not send orientation events. These previously triggered device_motion_unsupported errors.

Changes

  • Performance analysis - We have further tweaked our logging to enhance performance analysis in the long term.

12.08.2021 3.3.1

Fixed

  • Safari on iOS - Worked around circumstances when Safari provides corrupt imagery.
  • Safari on iOS - Liveness is now supported in an iframe on iOS 15 without the use of Iframe Bridge.

Changes

  • Face detection - Blazeface + TFJS upgraded to 0.0.7 and 3.8.0 respectively, enabling SIMD support, making things faster.
  • UI - Minor optimisations and simplified our shaders to reduce the WebGL load where possible.
  • UI - Low FPS Mode no longer presents an overpixellated UI. This should improve completion rates.
  • Crash handling - Improved detection of face detector crashes.
  • Performance Analysis - Improved distinction between the user clicking the exit button or exiting fullscreen.

04.08.2021 3.3.0

New

  • Camera selection - in multi camera environments, where browser support allows it, we have improved camera selection logic to prioritise user facing and higher resolution devices.

Fixed

  • Camera selection - multiple camera selection no longer blocks fullscreen.
  • Camera selection - we have fixed a regression where programmatically setting the camera device in slotted content failed.
  • Safari on macOS Catalina - we have worked around Safari's lack of fullscreen event support for this OS.

Please note our Browserslist database has been updated to 1.0.30001248.
