New Simplified Selection Strategies

You can now use simplified syntax with selection-strategy to handle common filtering by combining both the advice with the advice-for or advice-against keys.

Examples

selection-strategy {
  id (reject-bitcoin-payment-restaurants)
  match {
    food.AcceptsBitcoin(acceptsBitcoin) {
      to-input: food.FindRestaurant(_)
    }
  }
  advise-against ("${acceptsBitcoin}”)
}

selection-strategy {
  id (prefer-thai-restaurants)
  match {
    food.CuisineStyle(style) {
      to-input: food.FindRestaurant(_)
    }
  } 
  advise-for ("${style == ‘Thai’}”)
}

New Runtime Version 6

We've added a new runtime version that covers a number of runtime flags:

• auto-insert-navigation-conversation-drivers
• concepts-inherit-super-type-features
• no-auto-property-value-merging
• no-filtering-with-validation
• modern-default-view-behavior
• modern-prompt-rejection
• result-view-capsule-lock
• support-halt-effect-in-computed-inputs
• use-authorization-header-for-remote-endpoint-oauth
• use-input-views-for-selection-list-detail
• use-most-specific-instantiation-strategy
• no-fallback-dialog-in-views (New in this release)

New Brazilian Portuguese Reserved Utterances

We now support pt-BR reserved utterances.

New 'Contextual' EL Function

You can now use the contextual EL node evaluation function when you want check if a node is copied over from a previous request, preserving the earlier request's context.

For example, if a user asks a capsule "find sushi restaurants in Miami" and then follows up with "what about Chicago", the type of restaurant, "sushi," is contextual: it was given in the previous request.

Option to Display Result View With Halt

Actions now allow you to show a custom result-view using the display sub-key when you encounter an error and halt.

Example

...
    input (value) {
        type (MyValue) {
            validate {
            if (...) {
                halt {
                    dialog ("halting due to condition")
                    display (value.property)
                }
            }
            }
        }
    }
...

Updates to 'Time' Key in Activity Support

The time key in activity-support now allows a conditional block. The format for the conditional is as follows:

...
  time {
    if (isFuture(this.startDate)) { // uses a Date EL function to check if the startDate is upcoming
      expression(this.startDate)
    } else {
      expression(this.endDate)
    }
  }
...

Additionally, we've deprecated the ability to have empty time values. The key now must either have a simple time, such as (time (someDate)), or a conditional time.

We've also deprecated time values that are min (Optional) or max (Many). The key must now provide a node that contains one, and only one, value.

New Node Evaluation EL Functions

We've introduced three Expression Language node evaluation functions, which return a copy of the node with the evaluation state set in the following ways:

• pre(node): the node has not yet been evaluated (replaces the now deprecated node.pre()).
• mid(node): the node is currently being evaluated
• post(node): the node has already been evaluated

Examples

Old:

• I don't currently have a way to #{action (this.pre())}.
• I currently don't have the ability to #{action (this.pre())}.

New:

• I don't currently have a way to #{action(pre(this))}.
• I currently don't have the ability to #{action(pre(this))}.
