have redone Blocks & General folders. I don't have much time so it's time for someone else to take on the Item folder. Or we'll still use that c**p broken translation.

"All devices can be programmed using Lua 5.3" we support 5.2 and 5.3, not just 5.3

emmm I just thought oc updated to support lua 5.3 and we should update the manual as well. ocdoc.cil.li has also changed 5.2 into 5.3 lol

OpenComputers supports both Lua 5.2 and Lua 5.3. The latter is now the default, but it is not exclusive.
