V7 is my favorite for two reasons and two reasons only:
It allows me to pretend I have 4 other players playing with me,
and it allows me to manually make logic processors wait with one instruction.
so yeah, so stoked for the v7 thingy
If you go to the unstable builds via Mindustry (PC or Mobile) in the main menu, you can download V7 early for PC, mobile, and even for your server if you wished.
Just keep in mind that the V7 build (found in most recent build) you download from the unstable builds is not the full release, so schematics and saved games you made inside the build do have a chance to be incompatible with future stable releases.
