v0.1.3

Added

• A logo, and a recording of three games driven at once in the background, in the LeviMC Mods gallery.

Changed

• The README is rewritten for people writing test scripts. How it works inside, the pipe protocol and build notes moved to CONTRIBUTING.md.

v0.1.2

Added

• Loopback-only sockets (loopbackOnly, on by default): in background mode bind() to 0.0.0.0/:: is turned into a loopback bind, so a new game instance (a new exe path) no longer raises the Windows Firewall "allow access" prompt that stopped unattended runs. Outgoing connections (local servers, the internet) are unaffected; nothing outside the PC can reach a test game. state reports loopbackRebinds.

• Safety net in the Start-Game wrapper: worlds of the instance written in the last 15 minutes (the test world a harness just restored) are made single-player before the game starts, so a harness that forgot Set-WorldSinglePlayer no longer breaks other projects' parallel runs with "Blaze". Older worlds are never touched.

v0.1.1

Added

• Exclusive signaling lock also waits until no Minecraft.Windows process is left, so games started outside the lock cannot break online-multiplayer runs.
• Machine-wide signaling lock in harness-shim.ps1: every headless game holds it shared from Start-Game to Stop-Game; runs that join a server over NetherNet set $script:ExclusiveSignaling = $true and get the machine to themselves (each game's sign-in to the signaling service knocks out the previous one).

Fixed

• Virtual mouse clicks, wheel notches and camera moves arrived once per mouse device (twice on a PC with two mice): the virtual state now goes to one device and the others report idle.
• enable() could hang while installing the hooks: all hooks of a batch are now installed during a single thread pause, and nothing is logged while threads are paused.

v0.1.0

Added

• Control pipe (\.\pipe\<pipeName>, JSON lines) with ping, state, key, text, mouse, raw, release, focus, window, background and flush; input ops reply once the game thread has processed the input.
• Keyboard, text and pointer position dispatched through the game's own window procedure (subclassed window).
• Virtual GDK GameInput mouse (v2 IGameInputReading hooks): buttons, wheel and camera in menus and in the world; the real mouse and keyboard no longer reach a background game.
• Background mode: focus-loss messages swallowed (no pause), real client-area input swallowed, ClipCursor/SetCursorPos/GetCursorPos/GetAsyncKeyState/GetKeyState/GetKeyboardState/GetForegroundWindow/... report a virtual state, window activation hooks keep the game out of the foreground. Ctrl+Shift+F12 on the real keyboard turns it off.
• PowerShell client HeadlessInput.psm1 (input, screenshots via PrintWindow, per-instance pipes).
• harness-shim.ps1: drop-in replacement of the usual LeviLauncher harness helpers, plus redirects for harness C# input classes and Set-WorldSinglePlayer (parallel instances share one signaling-service ID and knock each other out of multiplayer worlds: "An error has occurred", code "Blaze").
• Start-HeadlessGame.ps1 (start an instance without activating it) and clone-instance.ps1 (cheap clone instances for parallel games).
• Trace mode: message, API-hook and GameInput statistics, and every input event that reaches the game, marked synthetic or real.
