Release Notes
Resolved Issues(Bugs below are eligible for Bug Bounty Program):

1. Strange os_timer_arm behavior.

Optimization:

1. Added SDIO slave driver. Developers are now able to implement AT commands based on SDIO interface by themselves.
2. Optimized SSL shakehand.
3. Upgraded second-level boot to support HSPI flash.
4. Added AirKiss library.
5. Updated sample code smart_config (esp_iot_sdk\examples\smart_config).
6. The 114th byte of esp_init_data_default.bin is modified to be 1. Please use the latest esp_init_data_default.bin.
7. Added sample code at_espconn (esp_iot_sdk\examples\at_espconn), showing how to transmit AT commands via the internet.

Added APIs:

1. SDIO slave APIs
   sdio_slave_init: initialize SDIO slave
   sdio_load_data: upload data to SDIO buffer.
   sdio_register_recv_cb: register Callbacks of data received by SDIO.
2. AirKiss APIs
   airkiss_version: get version information of AirKiss.
   airkiss_lan_recv: used to detect and analyze AirKiss data packets.
   airkiss_lan_pack: used to analyze AirKiss data packets, and to organize response packets waiting to be responded.
3. AT UART simulation APIs
   at_fake_uart_enable : enable AT UART simulation.
   at_fake_uart_rx : AT UART RX for simulation.

Known Issue:

1. SSL misbehavior.

AT_v0.60 Release Note:
Notice：

1. Since the release of ESP8266_NONOS_SDK_V1.5.0, AT firmware is too large to use 4Mbit flash. Please choose flash with at least 8Mbit capacity.
2. Firmware upgrade over-the-air process is changed a bit. We will upgrade the latest AT firmware to Espressif Cloud server only after it has been tested and the overall performance is guaranteed. Users may not be able to use AT+CIUPDATE in ESP8266_NONOS_SDK_V1.5.0 and other more advanced versions.

AT_v0.60 Release Note:

1. Added command AT+CWLAPOPT, which is used to config the attribute of the returned value of the command AT+CWLAP.
2. Added command AT+WPS, WPS supported.
3. Added command AT+MDNS, MDSN supported.
4. Added command AT+CWSTARTDISCOVER/AT+CWSTOPDISCOVER. AirKiss intranet detecting function is supported.
5. Optimized command AT+CIPSTART. The device can function as SSL client, and one SSL connection can be created at most.
6. Optimized AT+UART command.

Have fun!

发布说明
修正问题（符合乐鑫 Bug 赏金计划）:

1. os_timer_arm 行为异常的问题。

优化:

1. 新增支持 SDIO slave driver，开发者可自行实现基于 SDIO 的 AT 指令。
2. 优化 SSL 握手流程。
3. 更新二级 boot，以支持 HSPI flash。
4. 新增 AirKiss 库，支持内网发现功能。
5. 更新 smart_config 示例(esp_iot_sdk\examples\smart_config)。
6. esp_init_data_default.bin 第 114 字节修改为 1，请使用新版 esp_init_data_default.bin。
7. 新增 at_espconn 示例(esp_iot_sdk\examples\at_espconn)，示范通过网络发送 AT 指令。

Added APIs:

1. SDIO slave APIs
   sdio_slave_init :　初始化 SDIO slave
   sdio_load_data : 加载数据到 SDIO buffer
   sdio_register_recv_cb ：注册 SDIO 接收数据的回调函数
2. AirKiss APIs
   airkiss_version :　获得 AirKiss 库版本信息
   airkiss_lan_recv ：用于 AirKiss 内网发现功能，解析收到的数据包
   airkiss_lan_pack ：用于 AirKiss 内网发现功能，组织待回复的响应包
3. AT UART simulation APIs
   at_fake_uart_enable : enable AT UART simulation.
   at_fake_uart_rx : AT UART RX for simulation.

已知问题:

1. SSL 行为异常。

AT_v0.60 Release Note:
注意：

1. 从版本 ESP8266_NONOS_SDK_V1.5.0 起，AT 固件所需空间增大，无法再使用 4Mbit (512KB) Flash，请使用 8Mbit (1MB) 或以上容量 Flash。
2. 我司优化了 AT 固件的升级流程，AT 固件发布后，会等一段时间，待客户反馈稳定后，才上传到 Espressif Cloud 以供下载更新。因此，如果使用 ESP8266_NONOS_SDK_V1.5.0 及之后版本的 AT 固件暂时无法从 Espressif Cloud 升级。

AT_v0.60 更新说明:

1. 新增 AT+CWLAPOPT 指令，用于设置 AT+CWLAP 指令的返回结果属性。
2. 新增 AT+WPS 指令，支持 WPS 功能。
3. 新增 AT+MDNS 指令，支持 MDNS 功能。
4. 新增 AT+CWSTARTDISCOVER/AT+CWSTOPDISCOVER 指令，支持微信的内网发现功能。
5. 优化 AT+CIPSTART 命令，支持作为 SSL client，最多可创建 1 个 SSL 连接。
6. 修正设置波特率后最后一个字符错误的问题。
