v0.20.0
Vercel Labs announces a major shift to a full native Rust daemon, removing Node.js/Playwright entirely. Install size drops to 7 MB, memory use to 8 MB, and cold start to 617 ms. Includes benchmarks, Chromium installer hardening, and multiple bug fixes.
Minor Changes
Full Native Rust
- 100% native Rust -- Removed the entire Node.js/Playwright daemon. The Rust native daemon is now the only implementation. No Node.js runtime or Playwright dependency required. (#754)
- 99x smaller install -- Install size reduced from 710 MB to 7 MB by eliminating the Node.js dependency tree.
- 18x less memory -- Daemon memory usage reduced from 143 MB to 8 MB.
- 1.6x faster cold start -- Cold start time reduced from 1002ms to 617ms.
- Benchmarks -- Added benchmark suite comparing native vs Node.js daemon performance.
- Chromium installer hardened -- Fixed zip path traversal vulnerability in Chrome for Testing installer.
Bug Fixes
- Fixed --headed false flag not being respected in CLI (#757)
- Fixed "not found" error pattern in to_ai_friendly_error incorrectly catching non-element errors (#759)
- Fixed storage local key lookup parsing and text output (#761)
- Fixed Lightpanda engine launch with release binaries (#760)

@json-render/[email protected]
Vercel Labs unveils YAML wire format for json-render with streaming parser and yamlPrompt; adds universal edit modes for multi-turn spec refinement plus new edit workflows and helpers. Playground gains format toggle and token usage; prompt caching and CI parallelization boosted. A clear release of new capabilities.
Minor Changes
a8afd8b: Add YAML wire format package and universal edit modes for surgical spec refinement.
New
@json-render/yaml -- YAML wire format for json-render. Includes streaming YAML parser, yamlPrompt() for system prompts, and AI SDK transform (pipeYamlRender) as a drop-in alternative to JSONL streaming. Supports four fence types: yaml-spec, yaml-edit, yaml-patch, and diff.
Universal edit modes in @json-render/core -- three strategies for multi-turn spec refinement: patch (RFC 6902), merge (RFC 7396), and diff (unified diff). New editModes option on buildUserPrompt() and PromptOptions. New helpers: deepMergeSpec(), diffToPatches(), buildEditUserPrompt(), buildEditInstructions(), isNonEmptySpec().
Improved
Playground -- format toggle (JSONL / YAML), edit mode picker (patch / merge / diff), and token usage display with prompt caching stats.
Prompt caching -- generate API uses Anthropic ephemeral cache control for system prompts.
CI -- lint, type-check, and test jobs now run in parallel.
