The pop field in the :cpp:func:`protocomm_set_security` API is now deprecated. Please use the sec_params field instead of pop. This parameter should contain the structure (including the security parameters) as required by the protocol version used.
For example, when using security version 2, the sec_params parameter should contain the pointer to the structure of type :cpp:type:`protocomm_security2_params_t`.

* The ``pop`` field in the :cpp:func:`wifi_prov_mgr_start_provisioning` API is now deprecated. For backward compatibility, ``pop`` can be still passed as a string for security version 1. However, for security version 2, the ``wifi_prov_sec_params`` argument needs to be passed instead of ``pop``. This parameter should contain the structure (containing the security parameters) as required by the protocol version used. For example, when using security version 2, the ``wifi_prov_sec_params`` parameter should contain the pointer to the structure of type :cpp:type:`wifi_prov_security2_params_t`. For security 1, the behaviour and the usage of the API remain the same.
* The API :cpp:func:`wifi_prov_mgr_is_provisioned` does not return :c:macro:`ESP_ERR_INVALID_STATE` error any more. This API now works without any dependency on provisioning manager initialization state.
The pop field in the :cpp:type:`esp_local_ctrl_proto_sec_cfg_t` API is now deprecated. Please use the sec_params field instead of pop. This field should contain the structure (containing the security parameters) as required by the protocol version used.
For example, when using security version 2, the sec_params field should contain pointer to the structure of type :cpp:type:`esp_local_ctrl_security2_params_t`.
