• Empty syringe
  
• Ceiling sentry turret
  
• Mending syringe
  
• Hold the spawn key when spawning contraptions to see their silhouette before placing them down. This only applies to all contraptions saved in or after this version. This also applies to copying/pasting using the shortcuts.
  
• Empty syringes can push, pull, or be idle. Just like the blood tank.
  
• Limbs no longer have an upper bound on their liquid capacity.

• Gate "max power" property that you can set using the context menu.
  
• Minor details to most maps
  
• Brightness setting

• The entire syringe system. This will destroy all syringe mods created before this version. All syringe behaviour is now based on liquids. Syringes are liquid containers and every syringe effect is the result of foreign liquid entering the circulation. All syringes, except the empty syringe, are infinite.
  Attention to modders: you can derive from "OldSyringeBehaviour" instead of "SyringeBehaviour" if you want to keep using the old system.
  
• Almost all spawnable item thumbnails

- Phenomenal startup times if you have hundreds of Workshop subscriptions
- Infinite android "blood" amount
- A bug where you sometimes couldn't delete a contraption
- Other minor bugs

Now that the Discord server is gone, preview releases will be announced here instead. Preview builds are previews of the next version of the game. These versions are unfinished, probably dysfunctional, probably slow, and may mess up your saves. However, if you're willing to risk all of this to get new features as soon as possible, you are free to opt-in to the preview branch.



WIth that out of the way, 1.18 preview 1 is currently live on the preview branch.

A note to mod developers to have their mods working in 1.18:
[expand type=showmore]

Your mod will be rejected by the system if it includes any of the following identifiers:
- InteropServices
- Diagnostics
- Http
- FileStream
- File

If your mod is being rejected, this is usually because the code includes a 'using' directive followed by an item in the list above.

The "extern" modifier and "unsafe" keyword are also rejected.

Everything was slowly burning even though it wasn't on fire. This is my fault for improperly testing things and releasing them anyway. Either way it's fixed now, your version number won't change because who cares at this point

- Temperature unit setting
- Frozen limbs turn blueish
- In-game bug report form

- Minor performance improvements
- Nuclear explosions no longer set everything on fire (necessarily)
- Nuclear explosions now only burn things in its line of sight
- Darkened the pause menu
- Power gauge is less susceptible to heat damage
- Igniting things via the context menu is more clearly effective

- Burning-related bugs
- Strange wire colour bugs
- Magic purple glow? Probably fixed?? Inform me please
- Wires on piston head (and other objects) acting weird

- Ignition sound

- Weird water bugs
- Humans not burning for some reason
- Bleeding not fully stopping when temperature is under 0
- Insulators no longer catch fire
- Collision exit bug

- Basic temperature simulation
- Most hot metals glow
- Heat pipe
- Thermometer
- Insulator
- Hovercar
- Freezeray
- Heatray
- Heating element
- Cooling element
- No collision link (Phase link)
- Framerate limit setting (will only take effect if Vsync is disabled)
