# What's New: Week of August 10, 2026

1. **Simulations**: You can now build [simulation](/observability/simulations-overview) suites and run them against your assistants or squads to test and evaluate their behavior, with detailed results for each run.

2. **Unified Provider and Model Picker**: The assistant editor now combines provider and model into a single picker for your LLM, voice, and transcriber.

3. **Chat and Session Log Export**: You can now export selected rows from chat and session logs and use a bulk-actions bar, matching the call logs experience.

4. **SIP Transfer Improvements**: Blind [call transfers](/call-forwarding) now support a configurable `fallbackPlan`, SIP verb, and dial timeout, and cold-transfer outcomes now appear in call logs.

5. **Composer Improvements**: [Composer](/composer) is now more capable, reliable, and easier to use when building voice agents.
   * Upload files for it to reference, read current Vapi documentation directly, and follow new Vapi-built skills for building assistants, choosing models, managing tools, configuring phone numbers, and debugging calls.
   * Longer, multi-step tasks are far more reliable, with mid-task error recovery and progress that survives page refreshes and thread switches.
   * Connect Google Calendar from the conversation, clickable resource mentions with copyable IDs, and cleaner, collapsible activity timelines.
