+ * Implemented central security establishment when required
+ * Added additional security level options to the connection call
+ * Switched the unicast client and server to bidirectional CIS if available
+ * Added a new RSI advertising callback for CSIS
+ * Added multiple improvements to context handling, including public functions
+ to get contexts
+ * Added ordered access procedure for the CSIS client, as well as storing
+ active members by rank
+ * Added support for Write Preset Name in HAS
+ * Added support for using PACS for the broadcast sink role
+ * Cleaned up the MICP implementation, including renaming several structures
+ and functions
+ * Implemented the CAP Acceptor role
+ * Added ASCS Metadata verification support
+ * Started exposing broadcast sink advertising data to the application
+ * Added support for unicast server start, reconfigure, release, disable and

- * Added a new callback :c:func:`rpa_expired` in the struct :c:struct:`bt_le_ext_adv_cb`
- to enable synchronization of the advertising payload updates with the Resolvable Private
- Address (RPA) rotations when the :kconfig:option:`CONFIG_BT_PRIVACY` is enabled.
- * Added a new :c:func:`bt_le_set_rpa_timeout()` API call to dynamically change the
- the Resolvable Private Address (RPA) timeout when the :kconfig:option:`CONFIG_BT_RPA_TIMEOUT_DYNAMIC`
- is enabled.
- * Added :c:func:`bt_conn_auth_cb_overlay` to overlay authentication callbacks for a Bluetooth LE connection.
- * Removed ``CONFIG_BT_HCI_ECC_STACK_SIZE``.
- The Bluetooth long workqueue (:kconfig:option:`CONFIG_BT_LONG_WQ`) is used for processing ECC commands instead of the dedicated thread.
- * :c:func:`bt_conn_get_security` and `bt_conn_enc_key_size` now take a ``const struct bt_conn*`` argument.
+ * Added support for LE Secure Connections permission checking

+ * Added support for GATT CCCs in arbitrary locations as a client
+ * Extended the ``bt_conn_info`` structure with security information
+ * Added a new :kconfig:option:`CONFIG_BT_PRIVACY_RANDOMIZE_IR` that prevents

* Mesh
+ * Added support for selectable RPL backends
+ * Changed the way segmented messages are sent, avoiding bulk transmission
+ * Added an async config client API
+ * Added model publish support to the Health Client
+ * Moved relayed messages to a separate buffer pool
+ * Reduced delay of sending segment acknowledge message. Set
+ :kconfig:option:`CONFIG_BT_MESH_SEG_ACK_PER_SEGMENT_TIMEOUT` to 100 to get
+ the previous timing.
+ * Restructured shell commands
+
* Controller
+ * Made the new LLCP implementation the default one. Enable
