@ -11,6 +11,8 @@ and this project adheres to [Semantic Versioning](http://semver.org/spec/v2.0.0.
- GAP: simulate HCI_EVENT_REMOTE_NAME_REQUEST_COMPLETE if HCI Remote Name Request fails
- AVRCP Controller: Added send generic PASS THROUGH command
- HID Host: storage for HID Descriptors is now optional
- HCI: support newer AIROC Controller that require Download Mode with ENABLE_AIROC_DOWNLOAD_MODE
### Fixed
- GAP: store link key for standard/non-SSP pairing
### Changed
