+- [fix] Abort when panicking across the FFI boundary in corner cases. (#8)
+
+  `Future::drop`, panic payload from `Future::poll`, all `Waker` vtable functions `Waker::*` are
+  are now wrapped in `std::panic::catch_unwind`. An `abort` will be emitted when panic occurs,
+  since these functions are infallible and doesn't have sane value to return when panicking.
+  A short message would be printed to stderr before `abort`.
+
+- [fix] `FfiContext::with_context` is actually safe.
+
+# 0.3.0
+
+- [major] Introduce a Poll variant `Panicked` which returns when `Future::poll` panicked in order to
+  propagate panic to the host.
+- [minor] Public `FfiPoll` and `FfiContext`.
+
+# 0.2.1
