### Added
- example/le_mitm: MITM implementation that forwards ATT PDUs and allows for pairing
- GAP: gap_set_security_level sets required security level for incoming and outgoing connections
- cc256x: allow to specify power vector for each modulation type
### Changed
- L2CAP ERTM: send extended features request only once per HCI connection
