v0.21.0

0.21.0 (2026-07-06)

⚠ BREAKING CHANGES

• api: error responses now use errorCode instead of error_code. The managed API already strips the field, so managed clients are unaffected; self-hosted clients parsing error_code should read errorCode.

Features

• cli: add crw bench FRAMES harness (fb78bcb)
• cli: bench A/B flags, concurrency, crash-safe writes (7eb059e)
• core: add evidence & provenance primitives (4a638a0)
• core: expose sourceHash on scrape responses (b0d89f9)
• extract: prompt-based extraction and full meta-tag metadata (6453204)
• proxy: retry with default country on residential CONNECT tunnel failure (8aafdc8)
• search: thread per-request country to result-page scraping (be3b0d1)
• server: add /firecrawl/* compat namespace, own /v1 as native API (d9cb3b8)
