.. note:: During the initial step of the handshake (i.e. ``client_hello``), the server selects a cipher from the list that the client publishes. As the DHE_PSK/DHE_RSA ciphers have now been disabled by the above change, the server would fall back to an alternative cipher; if in a rare case, it does not support any other cipher, the handshake would fail. To retrieve the list of ciphers supported by the server, one must attempt to connect with the server with a specific cipher from the client-side. Few utilities can help do this, e.g. ``sslscan``.

禁用 Diffie-Hellman 密码交换模式
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
为避免 `安全风险 <https://github.com/espressif/mbedtls/blob/9bb5effc3298265f829878825d9bd38478e67514/include/mbedtls/dhm.h#L20>`__，当前版本已默认禁用 Diffie-Hellman 密码交换模式。以下为相应的禁用配置项：
|
||||
|
||||
- ``MBEDTLS_DHM_C``：原用于支持 Diffie-Hellman-Merkle 模块
|
||||
- ``MBEDTLS_KEY_EXCHANGE_DHE_PSK``：原用于支持 Diffie-Hellman 预共享密钥 (PSK) TLS 认证模式
|
||||
- ``MBEDTLS_KEY_EXCHANGE_DHE_RSA``：原用于支持带有前缀的密码套件 ``TLS-DHE-RSA-WITH-``
|
||||
|
||||
.. note:: 在信号交换的初始步骤（即 ``client_hello``）中，服务器会在客户端提供的列表中选择一个密码。由于 DHE_PSK/DHE_RSA 密码已在本次更新中禁用，服务器将退回到一个替代密码。在极个别情况中，服务器不支持任何其他的代码，此时，初始步骤将失败。若要检索服务器所支持的密码列表，需要首先在客户端使用特定的密码连接服务器，可以使用 ``sslscan`` 等工具完成连接。
|
||||
|
||||
从 X509 库中移除 ``certs`` 模块
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
- mbedtls 3.1 不再支持 ``mbedtls/certs.h`` 头文件。大多数应用程序支持从包含列表中安全删除该头文件。
|
||||

||||
对 ``esp_crt_bundle_set`` API 的重大更新
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
- 更新后，调用 :cpp:func:`esp_crt_bundle_set()` API 需要一个额外的参数 ``bundle_size``。该 API 的返回类型也从 ``void`` 变为了 :cpp:type:`esp_err_t`。
|
||||

- 函数 :cpp:func:`esp_http_client_read` 和 :cpp:func:`esp_http_client_fetch_headers` 现在会返回额外的返回值 ``-ESP_ERR_HTTP_EAGAIN`` 用于处理超时错误，即数据准备好前就已调用超时的情况。

重大更新（概述）
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
- 更新后，出现连接超时的情况时，函数 :cpp:func:`esp_transport_read` 将返回 ``0``，对其他错误则返回 ``< 0``。请参考 :cpp:enum:`esp_tcp_transport_err_t`，查看所有可能的返回值。

MQTT 客户端
|
||||
-----------
|
||||
|
||||
重大更新（概述）
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
- :cpp:type:`esp_mqtt_client_config_t` 的所有字段都分组存放在子结构体中。
|
||||
|
||||
以下为较为常用的配置选项：
|
||||
|
||||
- 通过 :cpp:member:`esp_mqtt_client_config_t::broker::address::uri` 配置 MQTT Broker
|
||||
- 通过 :cpp:member:`esp_mqtt_client_config_t::broker::verification` 配置 MQTT Broker 身份验证的相关安全问题
|
||||
- 通过 :cpp:member:`esp_mqtt_client_config_t::credentials::username` 配置客户端用户名

ESP-Modbus
|
||||
----------
|
||||
|
||||
重大更新（概述）
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
本次更新从 ESP-IDF 中移除了组件 ``freemodbus``，该组件已作为一个独立组件受到支持。可前往如下的独立仓库，查看更多有关 ``ESP-Modbus`` 的信息：
|
||||
|
||||
* `GitHub 中的 ESP-Modbus 组件 <https://www.github.com/espressif/esp-modbus>`__
|
||||
|
||||
在新版应用程序中， ``main`` 组件文件夹应包括组件管理器清单文件 ``idf_component.yml``，如下所示：
|
||||
|
||||
.. code-block:: text
|
||||
|
||||
dependencies:
|
||||
espressif/esp-modbus:
|
||||
version: "^1.0"
|
||||
|
||||
可以前往 `组件管理器注册表 <https://components.espressif.com/component/espressif/esp-modbus>`__ 找到 ``ESP-Modbus`` 组件。更多有关如何设置组件管理器的信息，请参考 `组件管理器文档 <https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-guides/tools/idf-component-manager.html>`__。
|
||||
|
||||
对于使用 ESP-IDF v4.x 及以后版本的应用程序，需要通过添加组件管理器清单文件 ``idf_component.yml`` 拉取新版 ``ESP-Modbus`` 组件。同时，在编译时，应去掉已过时的 ``freemodbus`` 组件。此项操作可通过项目 ``CMakeLists.txt`` 中的以下语句实现：
|
||||
|
||||
.. code-block:: cmake
|
||||
|
||||
set(EXCLUDE_COMPONENTS freemodbus)
|
