+## [0.4.3] - 2026-03-21
+
+### Added
+- `TangoRateLimitError` now exposes `wait_in_seconds`, `detail`, and `limit_type` properties parsed from the API's 429 response body.
+- `RateLimitInfo` dataclass for structured access to rate limit headers (`X-RateLimit-Limit`, `X-RateLimit-Remaining`, `X-RateLimit-Reset`, and per-window daily/burst variants).
+- `TangoClient.rate_limit_info` property returns rate limit info from the most recent API response.
+
+### Changed
+- `_request` now passes the full 429 response body to `TangoRateLimitError` (previously discarded), enabling callers to access `wait_in_seconds` and the specific limit type that was exceeded.
