Hello @Bua,
Welcome!
Please read Guidelines here:
Welcome to the Processing Foundation Discourse
Please include some minimal code to that will generate this error.
Processing 4.4.7 import menu:
Processing 4.4.8 import menu:
The above suggests that there may be more missing from Processing 4.4.8 than just the Serial Library.
This confirms it:
I am optimistic that there will be an update soon.
Code for above:
import processing.serial.*;
import processing.pdf.*;
import processing.net.*;
import processing.io.*;
import processing.dxf.*;
void setup()
{
}
void draw()
{
}
Please start another topic if it is not related to the serial library.
:)
