All notable changes to Fiw AntiCheat are listed here.

[2.0.0] - Initial public multi-loader release

Fiw AntiCheat is a professional mod verification and admin enforcement tool for Minecraft servers. It helps admins detect unwanted client mods, enforce official modpacks, and inspect readable player mod profiles.

Added

• Multi-loader support for:
  • Fabric 1.20.1
  • MinecraftForge 1.20.1
  • Fabric 1.21.1
  • NeoForge 1.21.1
• Whitelist mode for enforcing a captured official modpack list.
• Client challenge/response verification with nonce validation.
• Client mod reporting with ids, versions, fingerprints, and stable code markers.
• Bundled signatures for common unfair categories including cheat clients, x-ray, fullbright, freecam, autoclickers, and schematic printers.
• Admin commands:
  • /fiwmods reload
  • /fiwmods snapshot server
  • /fiwmods snapshot player <name>
  • /fiwmods profile <name>
• Per-player profile storage with current mods and recent change history.
• Readable profile grouping that separates real player-installed mods from Fabric, Forge, NeoForge, loader, API, and platform entries.
• Colored in-game profile output for easier admin scanning.
• Monitor-only mode for logging detections without kicking.
• Staff alerts for online operators.
• Bypass list for trusted users or test accounts.
• Optional Floodgate/Geyser Bedrock-player exemption by reflection.
• Mod icon metadata for Fabric, Forge, and NeoForge mod menus and launchers.

Notes

• The public mod name is now Fiw AntiCheat.
• Internal ids and config paths remain compatible with the original fiw-mods-api / fiw_mods_api identifiers.
• NeoForge does not publish a real Minecraft 1.20.1 artifact on the current NeoForge Maven, so the 1.20.1 Forge-family build targets MinecraftForge 47.x.

Requirements

• Fabric 1.20.1: Fabric Loader, Fabric API, Java 17
• MinecraftForge 1.20.1: Forge 47.x, Java 17
• Fabric 1.21.1: Fabric Loader, Fabric API, Java 21
• NeoForge 1.21.1: NeoForge 21.1.x, Java 21
• Install on both server and client for mod reporting.
