In theory, point release upgrades (e.g. v1.0.0 -> v1.0.2) contain bug fixes only and should be backwards compatible. They should be considered as a drop-in replacement. No need for multiple installations.
Oh I see, that is good to know. I will have to copy and paste my packages before deleting Julia 1.0.0 I assume.
No, just install new version of Julia v1.0.2, check everything works OK, then delete Julia v1.0.0. Packages should be unaffected.
I am looking at this right now. Indeed, everything seems to be identical. Thank you both for your fast replies!
I had the same exact issue. Removed the General folder with Windows Explorer and then followed with an “up” command in the REPL. All is good!
This worked for me too.
