Changelog

Breaking changes

  • Suggested actions is now a role="toolbar" and adopted roving tab index
    • TAB key will now land on the container, instead of individual button
    • While the focus is on the container, LEFT/RIGHT arrow keys are used to select different buttons (UP/DOWN for stacked layout)
    • Visual focus indicator is now two tiered. The default styling is same as the one we use in chat history
      • New style options added suggestedActionsVisualKeyboardIndicatorColor, suggestedActionsVisualKeyboardIndicatorStyle, suggestedActionsVisualKeyboardIndicatorWidth
    • Suggested actions container will be unmounted when there are no suggested action button to display
    • Suggested actions container is not longer a live region. The suggested action buttons will now be narrated by the chat history live region
  • Published NPM packages will now include /dist, /lib, and /src folders
    • The /dist folder was previously missing from our NPM packages
  • The activity.channelData.state property is being deprecated in favor of the updated activity.channelData['webchat:send-status'] property. Main differences include:
    • Previously, we would set the state property to "send failed" when the chat adapter failed to send the activity, or after passing a timeout as defined in styleOptions.sendTimeout
    • The new 'webchat:send-status' property will be set to "send failed" when the chat adapter fails to send the activity or after passing a hardcoded timeout of 5 minutes
    • See PR #4362 for details

Changed

  • Resolves #4301. Updated Dockerfile to support secure container supply chain, by @compulim in PR #4303
  • Resolves #4317. Updated package.json to allowlist /dist, /lib, /src, by @compulim in PR #4318
  • Resolves #4322. Improved error messages for sending activities, by @compulim in PR #4362
  • Resolves #4211. Added new useSendStatusByActivityKey hook to check the UI send status of an outgoing activity, by @compulim in PR #4362
    • The send status returned by this hook is designed to display different UIs that reflect the "sending", "send failed" or "sent" status of the activity
    • When modifying styleOptions.sendTimeout prop, the send status returned by this hook may transition from "send failed" to "sending", and vice versa
    • This is different from the send status provided by the chat adapter, namely activity.channelData['webchat:send-status']

Fixed

  • Fixes #4293 and #4296. Fixed accessibility issues for suggested actions, by @compulim, in PR #4314
    • Centralized live region of suggested actions into chat history live region for better live region control
    • Suggested actions container is now a role="toolbar" and uses roving tab index for multiple suggested action
  • Fixes #4319. Fixed navigation keys not working in suggested actions under IE Mode, by @compulim, in PR #4320
  • Fixes #4315. Cleaned up localization strings for suggested actions, by @compulim, in PR #4323
  • Fixes #4294. Screen reader should not read message twice when navigating in the chat history, by @compulim, in PR #4323

  • Fixes #4325. aria-keyshortcuts should use modifier keys according to KeyboardEvent key values spec, by @compulim, in PR #4323
  • Fixes #4327. In Adaptive Cards, TextBlock with style="heading" should have aria-level set, by @compulim, in PR #4329
  • Fixes #3949. For accessibility reasons, buttons in Adaptive Cards should be role="button" instead of role="menubar"/role="menuitem", by @compulim, in PR #4263
  • Fixes #4211. Screen reader should read when an activity was failed to send, by @compulim, in PR #4362, also fixed:
    • The "send failed" status on the activity should show up as soon as the chat adapter failed to send the activity
  • Fixes #4312. groupActivityMiddleware returning invalid value should not throw exceptions, by @compulim, in PR #4378.
  • Fixes #4386. Clicking on Adaptive Cards should not throw exception under IE11, by @compulim, in PR #4387, also fixed:
    • Prop type warning should not be shown for <ActivityRow>

4.12.1 patch: New style property adaptiveCardsParserMaxVersion

Web Chat 4.12.1 patch includes a new style property allowing developers to choose the max Adaptive Cards schema version. See PR #3778 for code changes.

To specify a different max version, you can adjust the style options, shown below:

  window.WebChat.renderWebChat(
    {
      directLine,
      store,
      styleOptions: {
        adaptiveCardsParserMaxVersion: '1.2'
      }
    },
    document.getElementById('webchat')
  );
  • Web Chat will apply the maximum schema available according to the Adaptive Cards version (as of this patch, schema 1.3) by default.
  • An invalid version will revert to Web Chat's default.

CHANGELOG

Added

  • Resolves #3777. Added a new adaptiveCardsParserMaxVersion style options for selecting the maximum supported version when parsing an Adaptive Cards, by @compulim in PR #3778

Fixed

  • Fixes #3773. Remove replyToId when using Direct Line Speech adapter, by @compulim in PR #3776

Samples

  • Fixes #3632. Update reaction button sample : Add replyToId to the postActivity object, by @amal-khalaf in PR #3769

Changelog

Breaking changes

A new accessibility update has been added to Web Chat from PR #3703. This change creates visual focus for the transcript (bold black border) and aria-activedescendent focused activity (black dashed border) by default.

To modify these styles, you can change the following props via styleOptions:

  transcriptActivityVisualKeyboardIndicatorColor: DEFAULT_SUBTLE,
  transcriptActivityVisualKeyboardIndicatorStyle: 'dashed',
  transcriptActivityVisualKeyboardIndicatorWidth: 1,
  transcriptVisualKeyboardIndicatorColor: 'Black',
  transcriptVisualKeyboardIndicatorStyle: 'solid',
  transcriptVisualKeyboardIndicatorWidth: 2,

The above code shows the default values you will see on Web Chat.

Changelog

[4.11.0] - 2020-11-04

Added

  • Resolves #3281. Added documentation on speech permissions for Cordova apps on Android, by @corinagum, in PR #3508
  • Resolves #3316. Refactored platform-neutral APIs into the new api package, to be reused on React Native component, in PR #3543 by @compulim
    • The new layering is core -> api -> component (HTML-only) -> bundle
    • Includes composition mode, platform-neutral React hooks, and localization resources
    • Most hooks are available in the new api package. Some hooks are only available on the existing component package, due to their platform dependency or coupling with visual components. For example, Web Worker, 2D canvas, useMicrophoneButton* are not available on the api package
    • Most implementations of middleware are only available in component package due to their coupling with visual components or platform features. Some implementations, (e.g. card action middleware and activity grouping middleware) are available on api package. For example:
      • Carousel layout and stacked layout is only available on component package due to their coupling with their respective visual components
      • For card action middleware, imBack, messageBack and postBack actions are available on api package, but call, openUrl and other platform-dependent actions are only available on component package
    • activityMiddleware, attachmentMiddleware, etc, now support arrays for multiple middleware
