Dear friend,
a very new I hope we’ll cooked version of the ESP8266 Arduino core just released.
It’s supposed to solve many of the 2.5.2 problems.
See here and update.
Best Regards,
Mike Kranidis

the spiff data can not be uploading ! I installed the latest python for windows but not working. any idea to fix ?
@mikekgr @PeteKnight
compiled error for me
IPAddress remoteIP() const override;
IPAddress is not supported by 2.6.0, only works with 2.5.0
//*************** Static IP list *********************//
IPAddress dns_ip ( 8, 8, 8, 8);
IPAddress gateway_ip ( 192, 168, 0, 254);
IPAddress subnet_mask(255, 255, 255, 0);
IPAddress ipMCU60 (192, 168, 0, 60);
IPAddress ipMCU56 (192, 168, 0, 56);
IPAddress ipMCU55 (192, 168, 0, 55);
IPAddress Server1 (192, 168, 0, 1);
IPAddress Server2 (192, 168, 0, 100);
//********************************* Setup ***************************************//
void setup()
{
Serial.begin(115200);
WiFi.config(ipMCU, gateway_ip, subnet_mask);
Blynk.connectWiFi (ssid, pass); // connect to wifi network
Blynk.config(auth, server_ip, port);
Blynk.connect();I check (using Ubuntu, not Windows) and IPAddress is still working OK, from 2.5.2 to 2.6.0.
You might check your code / installation. If still not OK,try reinstalling the library core then restart the IDE.
I downgraded to 2.5.0 and its ok
IPAdress issue is a known issue since 2.5.2 but never resolved.
Its due to ESP8266WiFi.h
and introduced 2.6.0 problems

I just tried that example and it works, I can’t see what is the difference with my scketch 
#include <ESP8266WiFi.h>
const char* ssid = "********";
const char* password = "********";
IPAddress staticIP(192,168,1,22);
IPAddress gateway(192,168,1,9);
IPAddress subnet(255,255,255,0);
void setup(void)
{
Serial.begin(115200);
Serial.println();
Serial.printf("Connecting to %s\n", ssid);
WiFi.config(staticIP, gateway, subnet);
WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED)
{
delay(500);
Serial.print(".");
}
Serial.println();
Serial.print("Connected, IP address: ");
Serial.println(WiFi.localIP());
}
void loop() {}Can you put the original / not-working code to see the difference.?
I compile your modified code and it’s OK using IPAddress with 2.6.0
#include <ESP8266WiFi.h>
//*************** Static IP list *********************//
IPAddress dns_ip ( 8, 8, 8, 8);
IPAddress gateway_ip ( 192, 168, 0, 254);
IPAddress subnet_mask(255, 255, 255, 0);
IPAddress ipMCU60 (192, 168, 0, 60);
IPAddress ipMCU56 (192, 168, 0, 56);
IPAddress ipMCU55 (192, 168, 0, 55);
IPAddress Server1 (192, 168, 0, 1);
IPAddress Server2 (192, 168, 0, 100);
IPAddress server_ip (192, 168, 0, 200);
uint32_t test;
#define port 8080
char auth[] = "xxxx";
char ssid[] = "xxxx";
char pass[] = "yyyy";
//********************************* Setup ***************************************//
void setup()
{
Serial.begin(115200);
WiFi.config(ipMCU60, gateway_ip, subnet_mask);
Blynk.connectWiFi (ssid, pass); // connect to wifi network
Blynk.config(auth, server_ip, port);
Blynk.connect();
}
void loop()
{
}
It’s not Blynk related, but this is a bug I just found in 2.6.0
For anyone who gets compiling error about uint32_t in esp8266com/esp8266/cores/esp8266/core_esp8266_features.h , just add
#include <stdint.h>
in front of
#include <stdlib.h> // malloc()
#include <stddef.h> // size_t

Still same issue:
libraries\ESP8266WiFi\src/WiFiServer.h:52:14: error: invalid abstract return type for member function ‘WiFiClient WiFiServer::available(uint8_t*)’
WiFiClient available(uint8_t* status = NULL);
#include <ESP8266WiFi.h>
#include <stdint.h>
#include <stdlib.h> // malloc()
#include <stddef.h> // size_t
const char* ssid = "********";
const char* password = "********";
IPAddress staticIP(192,168,0,22);
IPAddress gateway(192,168,0,254);
IPAddress subnet(255,255,255,0);I simplified the code :
WiFi.config("192,168,0,100", "192,168,0,254", "255,255,255,0");
conversion from ‘const char [14]’ to ‘IPAddress’ is ambiguous
there is a problem with the string in V2.6.0
I think it is due to IPV6 update
Can you use
WiFi.config(IPAddress(192,168,0,100), IPAddress(192,168,0,254), IPAddress(255,255,255,0));

WiFiServer.h:52:14: error: invalid abstract return type for member function ‘WiFiClient WiFiServer::available(uint8_t*)’
WiFiClient available(uint8_t* status = NULL);
Problem solved !
Thank you for your help. 
I ignored information about duplicates libraries !
I deleted all redundant libraries and now it’s ok for me with core 2.6.0

I think the core 2.4.2 has vulnerabilities KRACK issue. It’s fixed in 2.5.1 and above.

I think the WPA2 KRACK vulnerability was fixed in 2.4.0-rc2 and above.
