board package 3.0.0

[whcir911]

After upgrading to the 3.0.0 board package the syntax "HardwareSerial Serial3(PC11, PC10);" no longer compiles. I receive an error "error: conflicting declaration 'arduino::HardwareSerial Serial3'. Can someone show me the proper syntax to use the hardware serial ports
Thanks
