+## Changelog
+
+### v0.1.4
+
+- **Never-raises net widened:** an unexpected exception that escapes a send attempt (a
+  closed injected session → `RuntimeError`, a malformed proxy URL → `ValueError`) now
+  converts to a falsy `WebhookResult(ok=False, ...)` instead of propagating out of
+  `send()`, restoring the documented contract for those edge triggers.
+
+### v0.1.3
+
+- **429 always retries:** every `429` is now retryable under aretry's backoff + cap, not
+  only those with a parseable `retry_after`. A 429 with no body `retry_after` and no
+  `Retry-After` header (edge/Cloudflare/generic webhook) previously failed one-shot.
+
+### v0.1.2
+
+- Removed a dead `clock` constructor param (it was stored but never used). Pinned
+  `commons` to v0.2.1.
+
+### v0.1.1
+
+- **Never-raises contract hardened:** an error from a duck-typed proxy provider's
+  `get()`/`burn()` (e.g. `aioproxies.burn()` raising `ValueError` for an unknown proxy)
+  used to escape `send()`. Now any provider exception is caught and converted to a
+  failed result.
+- **Retry via `commons.aretry`:** 429/5xx retry moved onto the shared backoff engine —
+  5xx now backs off (was a tight no-backoff loop), and exhausted retries return the
+  **real** last status/body instead of a synthetic placeholder. Adds a `commons`
+  dependency.
