I currently have Processing 2.05b and 2.06b installed on my computer (Ubuntu 64-bit) and intend to upgrade to 2.08b and hopefully safely remove 2.05b, (and most likely 2.06b as well). I was wondering if there was a more simple way to update Processing than to download and install the package, and then remove the previous versions. If there isn't, is there a safe way to remove the old versions without messing up any dependencies? I'm sure this is a very novicelike question but I would greatly appreciate the community's assistance!
