Verifiers v0.1.15.dev1 Release Notes

Date: 05/12/2026

Highlights since v0.1.15.dev0

• Renderer-native multimodal transport. Threads renderer-emitted multi_modal_data through rollout generation, trajectory tokens, msgpack transport, and save output, with per-step delta encoding to avoid duplicating image payloads across rollout windows.
• Provider-specific reasoning controls. Maps reasoning_effort correctly for Anthropic models across native Anthropic calls and OpenAI-compatible Anthropic routes, including adaptive thinking defaults for newer Claude models.
• Runtime and release hardening. Removes the fixed ZMQ env request timeout, tightens v1 lifecycle handler discovery, and adds BugBot rules that keep release metadata and dependency sources publishable.
