Description

New Model Selection, Enhanced Edge Conditions, Simplified Credentials, and More

1. New Model Selection in Workflows: You can now specify the AI model used in workflows by setting the model property in workflow schemas. This allows choosing between OpenAI, Anthropic, Google, or custom models to better suit application requirements.

2. Enhanced Workflow Edge Conditions: Workflows now support Logic Edge Conditions and Failed Edge Conditions for edges. Specify logic edge conditions with Liquid JS templates to enable more complex logic and error handling within workflows, allowing for dynamic and responsive workflow designs.

3. Simplified Credential Configuration: Your uploaded credentials are now automatically configured with the correct fallback index, simplifying the setup process with cloud providers.

4. Updated End Reasons for ElevenLabs: The following endedReason values been removed from Call:

   • pipeline-error-eleven-labs-503-server-error
   • call.in-progress.error-providerfault-eleven-labs-503-server-error

   You should update your error handling code to reflect the current set of possible end reasons.

**Prompt Length Limitations**: The `globalPrompt` in workflows now has a maximum length of 5000 characters, and the `liquid` property in `LogicEdgeCondition` now has a maximum length of 1000 characters. Ensure prompts and conditions stay within these limits to prevent errors.
