### Agents Platform

- **Dynamic variables in simulated conversations**: Added support for [dynamic variable population in simulated conversations](/docs/api-reference/agents/simulate-conversation#request.body.simulation_specification.simulated_user_config.dynamic_variables), enabling more flexible and context-aware conversation testing scenarios.
- **MCP server integration**: Introduced comprehensive support for [Model Context Protocol (MCP) servers](/docs/eleven-agents/customization/tools/mcp), allowing agents to connect to external tools and services through standardized protocols with configurable approval policies.
- **Burst pricing for extra concurrency**: Added [bursting capability](/docs/eleven-agents/guides/burst-pricing) for workspace call limits, automatically allowing up to 3x the configured concurrency limit during peak usage for overflow capacity.

### ElevenCreative Studio

- **JSON content initialization**: Added support for initializing ElevenCreative Studio projects with structured JSON content through the `from_content_json` parameter, enabling programmatic project creation with predefined chapters, blocks, and voice configurations.

### Workspaces

- **Webhook management**: Introduced workspace-level webhook management capabilities, allowing administrators to view, configure, and monitor webhook integrations across the entire workspace with detailed usage tracking and failure diagnostics.
