Simple Updates Checker

A lightweight and asynchronous update-checking library.

• ⚡ Fully Asynchronous: Checks for updates in the background.
• 🌐 Dynamic Remote Changelog Localization: Add new languages for changelogs directly to remote config file.
• 📦 Multi-Version Support: Serve updates for multiple Minecraft versions (e.g., 1.20.1, 1.18.2, 1.12.2) from a single JSON Updates Information File.
• 🧠 Smart Version Comparison: Uses Maven's ComparableVersion. Never warns players about "updates" if they are running a newer dev/beta build.
• 💬 Interactive Chat Notifications: Provides clickable download links and hover tooltips directly in the player's chat.

How It Works

Host a single updates.json file on GitHub Pages, raw GitHub repo, or wherever you want.

Example updates.json

{
  "1.20.1": {
    "version": "1.2.0",
    "download_url": "" rel="noopener nofollow" target="_blank">https://www.curseforge.com/minecraft/mc-mods/your-mod",
    "changelog": {
      "en_us": "Added new cool features. Fixed crash with some mod.",
      "ru_ru": "Добавлены новые крутые штучки. Пофикшен краш с каким-то там модом.",
      "zh_cn": "新增了炫酷功能。修复了与某些模组冲突导致的崩溃问题。",
      "es_es": "Se han añadido nuevas funciones interesantes. Se ha solucionado un fallo que provocaba que el juego se colgara con algunos mods."
    }
  },
  "1.18.2": {
    "version": "1.0.0",
    "download_url": "" rel="noopener nofollow" target="_blank">https://www.curseforge.com/minecraft/mc-mods/your-mod",
    "changelog": {
      "en_us": "Initial mod release."
    }
  }
}

Localization Fallback Logic:
The library matches the player's client language code. For example: if es_mx (Mexican Spanish) is not found, it checks es, then falls back to en_us, and finally defaults to the first available language in the JSON.
