Please do NOT use this old version SDK, use the latest SDK instead.
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_15_04_24 release note
Note: AT added some functions so flash size need to be 1024KB or more than that.

Resolved Issues（Bugs below are eligible for Bug Bounty Program):
1. SSL connection may fail if SSL packet size larger than 2kBytes [PeteW ]
2. UDP remote IP to be 0.0.0.0 may cause reset [Jerry S]

8. ESP8266 softAP DHCP server record 8 DHCP client's IP at most [ygjeon]
9. To set static IP (wifi_set_ip_info) has to disable DHCP first(wifi_softap_dhcps_stop or wifi_station_dhcpc_stop)

AT_v0.23 Release Note:

1.AT+CWJAP add parameter "bssid", for several APs may have the same SSID
2.AT add status of ESP8266 station connect to AP

New AT commands:
1. AT+CIPSENDBUF: write data into TCP-send-buffer; non-blocking. Background task automatically handles transmission. Has much higher throughput.
2. AT+CIPBUFRESET: resets segment count in TCP-send-buffer
3. AT+CIPBUFSTATUS: checks status of TCP-send-buffer
4. AT+CIPCHECKSEGID: checks if a specific segment in TCP-send-buffer has sent successfully

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_15_04_24 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（符合乐鑫 Bug 赏金计划）:
1.SSL 连接可能失败，如果加密数据一包大于 2KBytes[PeteW ]
