New features
Ultravox Realtime is now a supported model. Configure agents to use Ultravox’s Realtime speech-to-speech model alongside existing providers. See LLM configuration. Override the base URL for OpenAI models. Point OpenAI-compatible models at a custom endpoint — useful for self-hosted gateways, regional deployments, or third-party proxies. See LLM configuration. Delete edges directly in the workflow builder. A delete button now appears on edges, so you can remove connections between nodes without opening a side panel. See Editing a workflow.Updates
Copy inbound webhook URLs in one click. A copy-to-clipboard button has been added next to inbound webhook URLs to speed up setup with external systems. See Webhook. Telephony signature validation is more reliable. Signature checks on incoming telephony events have been hardened so calls no longer drop on transient signature mismatches.Bug fixes
- Model overrides: API keys are now persisted with the model override at save time, so per-node model settings keep working after you change your global inference provider.
- API keys: Service API key validation has been corrected, so valid keys are no longer rejected on self-hosted setups. See API keys.
