dsyleixa:
currently I was using 1.8.5 (portable), now I want to upgrade to 1.8.8
I downloaded 1.8.8 zip (non-admin install)
after extracting, should I better
a) copy my old 1.8.5 portabe folder into the new 1.8.8 arduino folder, or
b) copy the new 1.8.8 arduino folder contents into the old 1.8.5 arduino folder
?
I definitely do not want to have to reinstall all my actual board cores from ESP and Adafruit boards anew...
It's easiest and safest to copy your old 1.8.5 portable folder into the new 1.8.8 arduino folder.
