 ## Changelog
 
+### v1.1.0
+
+- **Hang-guard on `request()` — a wedged backend can no longer park the loop forever.**
+  `request()` now wraps the backend call (`_raw_request`) in an outer `asyncio.wait_for`
+  deadline sized at the effective timeout **+ 5s slack** (`_HANG_GUARD_SLACK`). The
+  backend's own timeout still fires first in every healthy failure (slack, not
+  replacement); the envelope only trips when the backend's timer is dead — e.g. a
+  `curl_cffi` transfer that loses both its wakeup and its own enforcement in the same
+  failure — and its cancellation is what unwedges the orphaned transfer. The guard's
+  deadline is the per-call numeric `timeout` when given, else the session timeout
+  (`Session(timeout=...)`, default 10s); it composes cleanly with `request_with_retries`
+  (a wedge becomes one logged `ServerTimeoutError`, the next attempt proceeds, and an
+  exhausted retry returns a `FailureResponse` rather than hanging). **Opt-out:** a
+  session deliberately constructed unbounded (`Session(timeout=None)`) stays unguarded,
+  for genuinely long-lived calls (long-poll / streaming). Additive; no new knob.
+
 ### v0.1.13
 
 - **Session-default timeout no longer poisons pooled keep-alive connections.**
