The plan is to push 1.19 out on Monday; the last few multiblock machines have now been added, the tutorial works great, the Orbital Power Transmitter is ready for charging - a few more days of spit and polish and it'll be ready.
There's been tons and tons of fixes and improvements to Multiplayer and optimisations all across the board too.
This is planned to be the final patch before leaving Early Access - head over to the forum and have your say!
