+esp_iot_sdk_v1.1.0_15_05_22 Release Note 
+----------------------------------------
+Resolved Issues（Bugs below are eligible for Bug Bounty Program):
+1.Predictable TLS random values leads to insecure connections [projectgus]
+2.Connection problem in softAP+station mode.[智捷通]
+3.Low heap cause of reset when connect using SSL. [TuanPM]
+4.Smart config issue [bigbear]
+
+Document "2C_ESP8266__Programming Guide" updates:
+1.Update Demo code of rtc timer in appendix, and rtc timer will return to zero after deep-sleep wake up. [andrew]
+2.Add "3.espconn callback" in appendix to introduce espconn callbacks and the pointer may be different in different callback.[nagverma]
+3.Add RF description in “2.Overview”，if RF is disabled，ESP8266 station and soft-AP are both disabled.[yiaiguo]
+4.Revise name of API "wifi_softap_set_dhcps_offer_option" [ryan]
+
+Optimization:
+1.Solving the problem that some Wi-Fi events may be missing during test.
+2.UART Wi-Fi passthrough of UDP maybe change to oneway. [orgmar]
+3.Optimized FOTA to make upgrade faster
+4.ESP8266 soft-AP can connected to 8 stations at most, softap_config.max_connection default is 4
+5.ESP8266 station will connect to the stronger WiFi signal, if there are several APs sharing the same SSID.[stefan]
+6.Add 1024KB+1024KB flash map which need boot_v1.4+, more details in document "2A-ESP8266_IOT_SDK_User_Manual"
+7.Optimized PWM driver
+8.Revised structure mdns_info to support 10 groups of text data.
+9.Add user_rf_pre_init in user_main.c, user can set configuration of RF in it.
+
+Added APIs：
+1.sntp_set_timezone: set SNTP time zone.
+2.espconn_dns_setserver : set default DNS server
+3.system_uart_de_swap : disable UART0 swap
+4.system_get_flash_size_map: get flash size and flash map

+9.wifi_softap_get_station_num ：get number count of stations connected to ESP8266 soft-AP
+
+AT_v0.24 Release Note: 
+Note: For AT firmware to support FOTA, flash size need to be 1024KB or more than that.
+Optimization:
+1.Disable data echo of command "AT+CIPSEND"
+2.Optimized "AT+CWJAP?" to get channel and rssi
+3.ESP8266 station IP can only be got and inquiried after ESP8266 station connected to AP
+
+Added AT command： 
+1.AT+RFPOWER ：set maximum RF TX power
+2.AT+RFVDD ： set RF TX power according to VDD33
