2. Bug Bounty Program

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

1. The return value of system_adc_read is wrong.
2. The current is too high in light sleep mode.
3. The ESP8266 maybe reset if connected to a special router.

Optimization:

1. Updated libphy.a to version 972.
2. Updated libpp.a to version 10.1, revised issues about frequency offset and sleep mode.
3. Optimized IGMP function.
4. Optimized DNS function.
5. Optimized WPS function.
6. Optimized DHCP server function.
7. Optimized wifi_station_get_connect_status function.
8. Revised the issue that API system_adc_read and system_get_vdd33 may return wrong value.
9. Optimized API:
   bool espconn_secure_ca_enable(uint8 level, uint32 flash_sector);
   bool espconn_secure_cert_req_enable(uint8 level, uint32 flash_sector);

Added APIs:

1. system_adc_read_fast: ADC fast sampling.
2. wifi_fpm_auto_sleep_set_in_null_mode: set whether enter modem-sleep mode or not when WiFi is in NULL_MODE.

Known Issue:

1. espconn_send returns OK of sending UDP data, even if ESP8266 station disconnects to the AP.

AT_v1.1 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_v1.1 Release Note:
Optimization:

1. Optimized the behavior of writing Flash.
2. Optimized DHCP server function.
3. Updated command AT+SAVETRANSLINK to save domain name.

Have fun!

发布说明
修正问题（符合乐鑫 Bug 赏金计划）:

1. system_adc_read 返回值异常。
2. light sleep 模式下电流较高。
3. 连接特殊路由器可能导致系统重启。

优化:

1. 更新 libphy.a 到 972 版本。
2. 更新 libpp.a 到 10.1 版本，解决部分频偏及休眠问题。
3. 优化 IGMP 功能。
4. 优化 DNS 功能。
5. 优化 WPS 功能。
6. 优化 DHCP server 功能。
7. 优化 wifi_station_get_connect_status 函数。
8. 修正 system_adc_read、system_get_vdd33 返回值异常的问题。
9. 修改 API
   bool espconn_secure_ca_enable(uint8 level, uint32 flash_sector);
   bool espconn_secure_cert_req_enable(uint8 level, uint32 flash_sector);

Added APIs:

1. system_adc_read_fast: ADC 快速采样
2. wifi_fpm_auto_sleep_set_in_null_mode: 设置 Null Mode 模式下，是否自动进入 modem sleep

AT_V1.1 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_v1.1 更新说明:
优化:

1. 优化 AT 固件写 Flash 的行为。
2. 优化 DHCP server 功能。
3. 新增 AT+SAVETRANSLINK 对保存域名的支持。

日前有一部分用户反馈在使用 Eclipse 对最新的 SDK 默认编辑报错。

解决方案如下：
将固件根目录下的driver_lib文件夹（最新固件中新增的）拷贝到 app 文件夹中就可以正常编译了，注意目录结构

Someone feedback us that when they using Eclipse to compile latest SDK, there is error.

Please copy the driver_lib folder (newly added in latest SDK) under the root to the app folder. Then the compiling will be normal. Please pay attention to the folder structure.

Hi,

Till 2016-06-07, ESP8266_NONOS_SDK_V1.5.4_16_05_20 is the latest non-OS SDK. ESP8266_NONOS_SDK_V1.5.3.1 is just a middle version solved several bugs based on ESP8266_NONOS_SDK_V1.5.3.

截止到 2016-06-07，ESP8266_NONOS_SDK_V1.5.4_16_05_20 才是最新的非 OS SDK。ESP8266_NONOS_SDK_V1.5.3.1 只是一个中间版本，基于 ESP8266_NONOS_SDK_V1.5.3 解决了部分已知问题。
