I have node-red running on 1.0 without any issues. After installing version 1.02 I get a fault with the serial-node. Flows stopped due to missing node types. serial-port. This pops up even with a fresh installation and no flows (empty canvas) is this a known issue?

no. Which platform / os are you using ? How did you upgrade ? - Have you tried uninstalling / reinstalling the serialport node ?

Did you just upgrade node-red or did you also upgrade nodejs?

Yeah but did you upgrade nodejs too like @Colin asked?

I'm pretty certain the serial port code will need recompiling if you did.
