Greetings, gamers!

After many months of very hard work, Logic World's first major update is almost ready. v0.91 has some major performance upgrades, countless bug fixes and stability improvements, a few juicy new features like the Simulation Controls, and many smaller tweaks focused on improving quality-of-life like Chair-only Keys.

We hope you enjoy the update! If you're eager to try it out right away, follow the instructions below to check out the Preview versions. Once we've fixed all the nasty little bugs that the Preview People will surely find, the update will be fully released.

Help us localize the new features

If you speak a non-English language, we'd love your help translating Logic World to that language! All the new translation strings in 0.91 are ready for you to translate. Head over to https://logicworld.net/translate to get started.

Notification of upcoming price increase

Simultaneously with the full release of update 0.91, we're going to raise the price of Logic World from USD$12 to USD$15 (and regional equivalents). It has always been the plan to increase the price throughout Early Access, and this new price point reflects that 0.91 is a more polished and more valuable product. There will be several more price increases before we get to 1.0.

We are currently planning to never have a discount on Logic World, so the current price point is the lowest it will ever be. If you haven't bought Logic World yet, now would be a savvy time to do so :)

• The About menu, Languages menu, and Teleport menu can now be accessed from the Pause menu
  
• The markdown renderer does a better job of rendering lists and headers

• Fixed errors in the console when a player is standing on a component decoration (such as a Chair or the clicky part of a Button) and that component gets destroyed
  
• Fixed incorrect footstep sounds being played in some situations
  

Interactables

• Added support for outlining Interactables that are not part of components. This is used for the big clicky button in the test world, which is now outlined when you look at it

Modding

• If the server fails to broadcast its existence on the local network, it will now disable local network broadcasting instead of just crashing
  
• Reduced the minimum time between connections to a server from a single IP from 30 seconds to 3 seconds
  
• Messages in the server console announcing player leaves/joins are prettier
  

Technical

• Fixed the game not properly detecting supported network protocols, which was causing various nasty bugs that made the game unplayable in certain network setups or when no external network interfaces are available (#204, #333, #229)
  
• Updated Unity version to 2019.4.40f1
  
• Upgraded server runtime from .NET Core 3.1 to .NET 6.0
  
• Fixed there being an omega () in the name of a dll, which prevented the game from working properly in some environments
  
• All error messages and APIs are now PG-13
  
• The server now explicitly rejects wire requests between two outputs (previously, it would throw an error if sent one)
  
• The game now updates `___LastLoadedGameVersion` in `settings_master.succ` with the most recently loaded game version every time the game starts
  
• Error messages about parsing SUCC files are much more helpful, and now contain the file path & line number
  
• Various SUCC files, such as `settings_master.succ`, will now be automatically reloaded and their changes applied when the file is changed on disk.
  
• Configurable menu data is now stored in the profiled settings files instead of in a separate file for every menu. This means menu configurations now properly work with the settings profile system.
  
• Removed `config_override` files. All server config values are now stored only in `config.succ`
  
• Added a system for updating CustomData in saves when the layout for a component's CustomData changes between versions

• Changed default offline player names from "Citizen [random number]" to "Bobby #[random number]", and reduced the max size of the random numbers

• When taking a screenshot, the screen now flashes white
  
• The FPS counter no longer erroneously reports 60FPS for the first second it is enabled (#350)
