[Unreleased]

Changed

Fixed

Samples

  • Fixes #3473. Fix samples using activityMiddleware (from 4.10.0 breaking changes), by @corinagum in PR #3601

[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

Fixed

Samples

[4.10.1] - 2020-09-09

Breaking changes

  • To support Content Security Policy, glamor is being replaced by create-emotion. The CSS hash and rule name is being prefixed with webchat--css with a random value.

Fixed

  • Fixes #3431. Removed delay of first activity with replyToId pointing to a missing activity, by @compulim in PR #3450
  • Fixes #3439. Use consistent return type in default CardActionContext.getSignInUrl(), by @stevengum in PR #3459
  • Fixes #3444. Make suggested actions container height styleOption flexible, by @corinagum in PR #3456

Changed

Samples

[4.10.0] - 2020-08-18

Breaking changes

  • Due to the complexity, we are no longer exposing <CarouselLayout> and <StackedLayout>. Please use <BasicTranscript> to render the transcript instead.
  • With the new activity grouping feature:
    • Customized avatar cannot be wider than styleOptions.avatarSize. If you want to show a wider avatar, please increase styleOptions.avatarSize.
    • If customized avatar is rendering false, bubble will still be padded to leave a gutter for the empty customized avatar. To hide gutter, please set styleOptions.botAvatarInitials and styleOptions.userAvatarInitials to falsy.
  • Default bubble nub offset is set to 0, previously "bottom" (or -0)
    • Previously, we put the bubble nub at the bottom while keeping the avatar on top. This is not consistent in the new layout.
  • By default, we will group avatar per status group.
    • If you want to switch back to previous behaviors, please set styleOptions.showAvatarInGroup to true.
  • Default botAvatarInitials and userAvatarInitials is changed to undefined, from "" (empty string)
    • When the initials is undefined, no gutter space will be reserved for the avatar.
    • When the initials is "" (empty string), gutter space will be reserved, but not avatar will be shown.
  • useRenderActivity hook is being deprecated, in favor of the new useCreateActivityRenderer hook.
  • useRenderActivityStatus hook is being deprecated, in favor of the new useCreateActivityStatusRenderer hook.
  • useRenderAvatar hook is being deprecated, in favor of the new useCreateAvatarRenderer hook.

Change in general middleware design

This change will impact middleware which use downstream result.

Previously, when a middleware is called, they are passed with a single argument.

Starting from 4.10.0, multiple arguments could be passed to the middleware. All middleware should pass all arguments to the downstream middleware. This change enables future extension to the middleware pattern.

For example, a passthrough middleware was:

() => next => card => next(card)

It should become:

() => next => (...args) => next(...args)

This also applies to the render function returned by activity middleware. The previous signature was:

() => next => card => children => next(card)(children)

It should become:

() => next => (...setupArgs) => (...renderArgs) => next(...setupArgs)(...renderArgs)

Note: Please read the following section for another change in the activity middleware signature for decorators.

Change in activity middleware

This change will impact activity middleware used for decoration.

Previously, when an activity middleware hid a specific activity from view, it returned a function, () => false.

Starting in 4.10.0, if an activity needs to be hidden from the view, the middleware should return false instead of () => false. This change allows transcript to correctly group activities and ignore activities that are not in view.

To avoid the TypeError: x is not a function error, all middleware should be aware that downstream middleware may return false instead of a function.

For example, when an event activity is hidden from the view, the terminator middleware will now return false. All decoration middleware should check if the downstream result is false (or falsy value), and return the value as-is to upstream middleware.

Previously, a simple decorator was:

() => next => (...setupArgs) => (...renderArgs) => {
  const render = next(...setupArgs);
  const element = render(...renderArgs);

  return element && <div>{element}</div>;
}

It should check the result from downstream middleware. If it is falsy, it should return as-is to the upstream middleware:

() => next => (...setupArgs) => {
  const render = next(...setupArgs);

  return render && (...renderArgs) => {
    const element = render(...renderArgs);

    return element && <div>{element}</div>;
  };
}

    • For openUrl card action, we are now allow-listing the URL scheme using the same allow list from the default Markdown + sanitize engine, which includes data, http, https, ftp, mailto, sip, and tel
