Hi,
I made a schematic, then laid out the pcb.
Now after numerous changes the annotation of the schematic was not logical. So I re-annotated the SCH and forwarded the changes to PCBNEW. I am guessing KiCAD uses the ref as the association and not some sort of key in case the reference changes… because now the board is a mess.
Any recommendation on how to go about it updating annotation of SCH and forwarding the changes to a PCB?
Kind Regards
When you load the netlist again in PCBnew, there is an option to use timestamps instead of references…
[edit] deleted my org answer as I misread OP
Annotate by timestamp? I think this was discussed on here not too long ago.
Hey! Completely changing your post like that… 
Wow Thanks Joan and Madworm for the speedy replies!! 
Yes perfect, that is a brilliant feature! Well done to the KiCAD team!
(PS I did do a search but I didn’t come across the timestamp feature… maybe the next guy which words it the way I did will find my post
