@rkast4321, which device exactly? Did you revise your code in regards to "breaking changes" in v1.0.0?
BREAKING CHANGES
Beginning with 1.0.0 release, Particle.publish() and Particle.subscribe() methods will require event scope to be specified explicitly. This means using PRIVATE or PUBLIC for Particle.publish() and MY_DEVICES or ALL_DEVICES for Particle.subscribe(). Please update your apps to include the event scope to avoid compilation errors in firmware >0.7.0. Deprecation warnings for this change began with 0.7.0-rc.3. #13651
[Core/Photon/P1] WiFi.RSSI() must be cast to int8_t when used inline with Serial.print() to produce correct results. E.g. Serial.printlnf("%d", (int8_t) WiFi.RSSI() ); Electron is not affected. #1423
