请勿使用本旧版本 SDK，建议使用 最新发布 SDK。
Since the launch of the Espressif Bug Bounty Program beginning on March 20, 2015, we’ve received some important bug reports across the world which have helped us a lot in improving our SDK and our support to customers as well. We’d like to name them in our release note to show our great appreciations to all of the reporters for their feedback.
ESP8266_NONOS_SDK_V1.0.1_b1_15_04_02 release note
Note: This is a beta version which solved some reported problem, without full function test !
Fix bugs:
1. SmartConfig loses one bit of SSID [BBP#14 reporter (zhaoyunhua)]
2. Connection to ESP8266 softAP failed after SmartConfig［BBP#24 reporter (yuling)]
3. Exception occurred while updating spi_flash_write [BBP#13 reporter DarkByte ]
Optimize：
1.espconn_set_opt: set configuration of TCP connection, add parameter for TCP keep alive
Add APIs:
1.espconn_clear_opt: clear configuration of TCP connection
2.espconn_set_keepalive: set configuration of TCP keep-alive to detect if TCP connection broke
3.espconn_get_keepalive: get configuration of TCP keep-alive
AT_v0.23_b1_on_sdk_v1.0.1 release note
Note: AT added some functions so flash size need to be 1024KB or more than that.
Fix bug:
1.Always "busy" if TCP connection abnormally broke during AT+CIPSEND
Optimize:
1. Add UDP transparent transmission function ［BBP#1 reporter (wu)］
2. Optimize the initial value of AT+CWDHCP? ［BBP#10 reporter (ondrej.dolejsi)]
3.Add TCP keep-alive function in AT+CIPSTART
Add AT command:
1.Add AT+CIPSENDEX which support quit from sending mode by "\0" (so an useful "\0" need to be "\\0") [BBP#7 reporter (Jerry Sy)]
自从乐鑫信息科技于 2015-03-20 启动 Bug 赏金计划以来，我们收到了一些重要问题反馈及建议，感谢世界各地的开发者对 ESP8266的关注，推动我们的软件更进一步，技术支持团队也得到迅速地成长。我们将在如下发布日志中点名感谢您的帮助。
ESP8266_NONOS_SDK_V1.0.1_b1_15_04_02 release note
注意: 这是一版 beta 测试版软件，未经过详细测试，解决部分收集到的反馈和问题 ！
修正问题:
1. SmartConfig 可能丢掉 SSID 中的一位 [BBP#14 reporter ( 赵云华)]
2. SmartConfig 之后，连接ESP8266 softAP 失败［BBP#24 reporter ( 煜玲)]
3. 用户调用 spi_flash_write 自行实现升级出现Exception [BBP#13 reporter DarkByte ]
优化：
1.espconn_set_opt: 设置 TCP 连接的相关配置，增加 keep-alive 的使能参数
新增 APIs:
1.espconn_clear_opt: 清除 TCP 连接的相关配置
2.espconn_set_keepalive: 设置 TCP keep-alive 参数，侦测 TCP 连接是否断开
3.espconn_get_keepalive: 查询 TCP keep-alive 参数
AT_v0.23_b1_on_sdk_v1.0.1 release note
注意: 由于AT 新增部分功能，占用空间增大，请使用 1024KB 或以上容量的 flash
修正问题:
1. 在AT+CIPSEND 发送数据的过程中，TCP 连接异常断开，可能导致始终响应 "busy"
优化:
1. 增加 UDP透传 ［BBP#1 reporter (无)］
2. 优化 AT+CWDHCP? 返回的初始值［BBP#10 reporter (ondrej.dolejsi)]
3. 指令 AT+CIPSTART增加 TCP keep-alive 参数
新增 AT 指令 :
1. 新增指令“AT+CIPSENDEX”支持在传输中遇到字符 "\0" 则退出传输 (因此 "\0" 需要转义为 "\\0") [BBP#7 reporter ( Jerry Sy )]
Thanks for your interest in ESP8266 !
