# What's New: Week of June 15, 2026

1. **Claude Haiku (Global)**: Now available as a model through [Amazon Bedrock](https://docs.vapi.ai/providers/model/anthropic-bedrock) for assistants.

2. **Pronunciation Dictionary Management in Voice Config**: [Pronunciation dictionaries](https://docs.vapi.ai/assistants/pronunciation-dictionaries) configured via the API can now be viewed and managed directly in an assistant's voice settings in the dashboard.
   * Stale dictionary references are flagged when a voice changes to a model that cannot apply them.

3. **Rotating Tool Messages**: You can now configure multiple [message variants](https://docs.vapi.ai/tools/custom-tools) for a tool, and the assistant picks one at random so longer calls feel less repetitive.

4. **Dynamic Variables in Test Calls**: A dialog lets you set [dynamic variable](https://docs.vapi.ai/assistants/dynamic-variables) values before starting a test call from the dashboard.

5. **Concurrency and Rate Limits in Organization Settings**: Your [call concurrency](https://docs.vapi.ai/calls/call-concurrency) cap and API request rate limit now appear as read-only fields in Organization Settings.

6. **Fixes and Improvements**:
   * Cartesia voice overrides in squads now apply correctly instead of falling back to a hard-coded default.
   * Duplicate tools sharing the same `function.name` are de-duplicated during model streaming, preventing duplicate tool calls.
   * The call concurrency chart in analytics now renders correctly.
