20### Added
21- Port for Windows with Zephyr HCI Firmware connected via serial port
22- em9304: ability to upload patch containers during HCI bootup.
23- GATT Client: gatt_client_request_can_write_without_response_event() causes GATT_EVENT_CAN_WRITE_WITHOUT_RESPONSE
24- SM: new event SM_EVENT_PAIRING_COMPLETE
25- GAP: support iteration over stored Classic link keys: gap_link_key_iterator_init, gap_link_key_iterator_get_next, gap_link_key_iterator_done
26- GAP: add gap_delete_all_link_keys
27
28### Changed
29- GATT Client: round robin for multiple connections
30- ATT Dispatch: round robin for ATT Server & GATT Client
31- L2CAP: round robin for all L2CAP channels (fixed and dynamic)
32- btstack_link_key_db: addition functions for link key iteration
33- GAP: LE scanning enabled not reset on HCI Reset -> can be enabled before HCI Power Up
34- CSR: set all keys in psram instead of default

42### Added
43- Port for Windows with Zephyr HCI Firmware connected via serial port
44- em9304: upload patch containers during HCI bootup
45- Makefile for STM32-F4Discovery port
46- support for console out via SEGGER RTT
47- LE Data Channels example in BTstack and [https://github.com/bluekitchen/CBL2CAPChannel-Demo](iOS example on GitHub)
48- LE Streamer Client can send as fast as possbile as well
49- L2CAP: option to limit ATT MTU via l2cap_set_max_le_mtu
50
51### Changed
52- HCI: allow to set hci_set_master_slave_policy (0: try to become master, 1: accept slave)
53- GAP: gap_set_connection_parameters includes scan interval and window params
54- GATT Client: GATT_EVENT_MTU indicates max MTU
55- ATT DB Util: attribute handle is returned for new Services and Characteristics
56
57### Fixed
58- Windows: retry serial port operations if not all bytes have been read/written
59- HFP: avoid buffer overflows setting up messages
60- SBC Decoder: improved error handling for invalid SBC audio data
61- GAP: fix Connection Parameter Response in Central role
62- ATT DB Util: update pointer to database in case of realloc
63- GATT Client: set UUID16 field if 16-bit UUID is stored as UUID128
64- GAP: release HCI Connnection after gap_le_conne
65- ATT: Exchanged MTU is propagate to ATT Server and GATT Client

68## Changes December 2017

70### Added
71- Introduced btstack_network.h network interface abstraction
72- btstack_network_posix implementation using Linux tun/tap interface
73- WICED: support for btstack_stdin (HAVE_STDIN)
74- GATT Server: Writes to GATT Client Characteristic Configuration are stored in TLV and restored on reconnect. The db.h file generated from db.gatt needs to be re-created.
75- TLV: global TLV instance available via btstack_tlv_get_instance() (src/btstack_tlv.h)
76- TLV: POSIX implementation that appends to a file on disk (platform/posix/btstack_tlv_posix.c
77- LE Device DB TLV: overwrite oldest entry if no free entries available
78- SM: allow to set fixed passkey in display role using sm_use_fixed_passkey_in_display_role
79- Example/hid_host_demo with HID parser and support for basic US keyboard layout
80- EM9304: custom HCI Transport implementation for EM9304 on top of btstack_em9304_spi.h platform abstraction only requires hal_em9304_spi.h to be implemented for new ports
81- Port for Apollo2 MCU with EM9304 (ports/apollo2-em9304)
82
83### Changed
84- panu_demo: uses btstack_network.h now
85- WICED: configure printf to replace Linefeed with CRLF
86- SBC: split btstack_sbc_bludroid.c into seperate encoder and decoder implementations
87
88### Fixed
89- RFCOMM: support connection requests during connection failure
90- L2CAP: support connection requests during connection failure
91- L2CAP: fix default remote MTU as 672 instead of 48 (Minimal MTU)
92- HCI: avoid double free during halting
93- SM: fixed reconnect using legacy pairing in slave role
