+# 0.2.0
+
+## Breaking Changes
+
+- [ManufacturerData] `deserialize/1` returns `{:error, bin}` instead of
+  `{:error, {:unhandled_company_id, bin}}`
+- [Event] `deserialize/1` returns `{:error, bin}` instead of
+  `{:error, {:bad_event_code, bin}}`
+- [Apple] when attempting to deserialize a non-binary term, crash
+- [AdvertisingReport] `deserialize/1` always returns
+  `{status, %AdvertisingReport{}}`
+- [Device]
+  - when attempting to deserialize a non-binary term, crash
+  - faults nested within a device discovered during deserialization will no
+    longer be realized through tuples like `{:early_termination, 0}`, instead
+    the violating binary will be returned as-is
+
+## Enhancements
+
+- [Apple] `deserialize/1` returns `{:error, bin}` instead of crashing on invalid
+  input
+- [ArrayedData] `deserialize/1` returns `{:error, bin}` instead of crashing on
+  invalid input
+- [Transport]
+  - `LE` is always included as a handler WRT `Transport`
+  - errors during deserialization no longer prevent a Bluetooth event from being
+    dispatched to handlers
