Hi,

What does the msg below mean? I'm not using a serialport node:

> [node-red-node-serialport/serialport] Error: libnode.so.64: cannot open shared object file: No such file or directory

TIA

Look in the Manage Palette option under the hamburger menu. If it shows installed and not in use then remove it.  
If it shows in use then look in Configuration Nodes to see if you have any unused serial config nodes and delete them. Then you should be able to remove it.

This' interesting. I cannot find any leftover code anywhere.
