5.9.0

(feat): Add retryStatusCodes config with "legacy" and "recommended" modes. Legacy (default) preserves current behavior (408, 409, 429, >= 500). Recommended retries only transient codes (408, 409, 429, 502, 503, 504), avoiding idempotency issues with 500. A 6.0.0 migration auto-pins legacy for upgrading users.

5.8.4

(chore): Bump @fern-api/generator-cli to 0.9.21, which includes @fern-api/replay 0.14.0 with fixes for silent customization loss across apply and resolve paths, per-patch-region diff, and clean follow-up patch preservation.
