 ### Creating a Release
 
-1. Update version in `package.json`
+**⚠️ IMPORTANT: Semantic Versioning Required**
+
+This project uses **strict semantic versioning with numerical versions only**:
+- ✅ **Valid**: `2.0.1`, `2.0.11`, `2.1.0`, `3.0.0`
+- ❌ **Invalid**: `2.0.2b`, `2.0.2a`, `2.0.1-beta`
+
+**Format**: `MAJOR.MINOR.PATCH` (e.g., `2.0.11`)
+
+The auto-update system requires semantic versioning for proper version comparison. Letter suffixes are not supported.
+
+**Steps:**
+
+1. Update version in `package.json` (use numerical format only, e.g., `2.0.11`)
 2. Commit and push to `main`
 3. Create and push a version tag:
 
 ```bash
-git tag v2.0.1
-git push origin v2.0.1
+git tag v2.0.11
+git push origin v2.0.11
 ```

+## 📌 Versioning Policy
+
+**⚠️ Important: Semantic Versioning Required**
+
+This project follows **strict semantic versioning** with **numerical versions only**:
+
+- ✅ **Valid**: `2.0.1`, `2.0.11`, `2.1.0`, `3.0.0`
+- ❌ **Invalid**: `2.0.2b`, `2.0.2a`, `2.0.1-beta`, `v2.0.2b`
+
+**Format**: `MAJOR.MINOR.PATCH` (e.g., `2.0.11`)
+
+- **MAJOR**: Breaking changes
+- **MINOR**: New features (backward compatible)
+- **PATCH**: Bug fixes (backward compatible)
+
+**Why?** The auto-update system requires semantic versioning for proper version comparison. Letter suffixes (like `2.0.2b`) are not supported and will cause update detection issues.
+
+---
+
 ## 📋 Changelog
 
-### 🆕 v2.0.2 *(Latest)*
+### 🆕 v2.0.2b *(Minor Update: Performance & Utilities)*  
+- 🌎 **Language Translation** — A big welcome for Spanish 🇪🇸 and Portuguese (Brazil) 🇧🇷 players! **Language setting can be found in the bottom part of Settings pane.**
+- 💻 **Laptop/Hybrid GPU Performance Issue Fix** — Added automatic GPU detection system and options to choose which GPU will be used for the game, *specifically for Linux users*.
+- 👨‍💻 **In-App Logging** — Reporting bugs and issues to `Github Issues` tab or `Open A Ticket` channel in our Discord Server has been made easier for players, no more finding logs file manually.
+- 🛠️ **Repair Button** — Your game's broken? One button will fix them, go to Settings pane to Repair your game in one-click, **without losing any data**. If doing so did not fix your issue, please report it to us immediately!
+- 🐛 **Fixed Bugs** — Fixed issue [#84](https://github.com/amiayweb/Hytale-F2P/issues/84) where mods disappearing when game starts in previous launcher (v2.0.2a).
+
+### 🆕 v2.0.2a *(Minor Update)*  
+- 🧑‍🚀 **Profiles System** — Added proper profile management: create, switch, and delete profiles. Each profile now has its own **isolated mod list**.  
+- 🔒 **Mod Isolation** — Fixed ModManager so mods are **strictly scoped to the active profile**. Browsing and installing now only affects the selected profile.  
+- 🚨 **Critical Path Fix** — Resolved a macOS bug where mods were being saved to a Windows path (`~/AppData/Local`) instead of `~/Library/Application Support`. Mods now save to the **correct location** and load properly in-game.  
+- 🛡️ **Stability Improvements** — Added an **auto-sync step before every launch** to ensure the physical mods folder always matches the active profile.  
+- 🎨 **UI Enhancements** — Added a **profile selector dropdown** and a **profile management modal**.
+  
+### 🆕 v2.0.2 
 - 🎮 **Discord RPC Integration** - Added Discord Rich Presence with toggle in settings (enabled by default)
 - 🌐 **Cross-Platform Multiplayer** - Added multiplayer patch support for Windows, Linux, and macOS
 - 🎨 **Chat Improvements** - Simplified chat color system

+# Auto-Updates System
+
+This document explains how the automatic update system works in the Hytale F2P Launcher.
+
+## Overview
+
+The launcher uses [electron-updater](https://www.electron.build/auto-update) to automatically check for, download, and install updates. When a new version is available, users are notified and the update is downloaded in the background.
+
+## How It Works
+
+### 1. Update Checking
+
+- **Automatic Check**: The app automatically checks for updates 3 seconds after startup
+- **Manual Check**: Users can manually check for updates through the UI
+- **Update Source**: Updates are fetched from GitHub Releases
+
+### 2. Update Process
+
+1. **Check for Updates**: The app queries GitHub Releases for a newer version
+2. **Notify User**: If an update is available, the user is notified via the UI
+3. **Download**: The update is automatically downloaded in the background
+4. **Progress Tracking**: Download progress is shown to the user
+5. **Install**: When the download completes, the user can choose to install immediately or wait until the app restarts
+
+### 3. Installation
+
+- Updates are installed when the app quits (if `autoInstallOnAppQuit` is enabled)
+- Users can also manually trigger installation through the UI
+- The app will restart automatically after installation
+
+## Version Detection & Comparison
+
+### Current Version Source
+
+The app's current version is read from `package.json`:
+
+```json
+{
+  "version": "2.0.2b"
+}
+```
+
+This version is embedded into the built application and is accessible via `app.getVersion()` in Electron. When the app is built, electron-builder also creates an internal `app-update.yml` file in the app's resources that contains this version information.
+
+### How Version Detection Works
+
+1. **Current Version**: The app knows its own version from `package.json`, which is:
+   - Read at build time
+   - Embedded in the application binary
+   - Stored in the app's metadata
+
+2. **Fetching Latest Version**: When checking for updates, electron-updater:
+   - Queries the GitHub Releases API: `https://api.github.com/repos/amiayweb/Hytale-F2P/releases/latest`
+   - Or reads the update metadata file: `https://github.com/amiayweb/Hytale-F2P/releases/download/latest/latest.yml` (or `latest-mac.yml` for macOS)
+   - The metadata file contains:
+     ```yaml
+     version: 2.0.3
+     releaseDate: '2024-01-15T10:30:00.000Z'
+     path: Hytale-F2P-Launcher-2.0.3-x64.exe
+     sha512: ...
+     ```
+
+3. **Version Comparison**: electron-updater uses semantic versioning comparison:
+   - Compares the **current version** (from `package.json`) with the **latest version** (from GitHub Releases)
+   - Uses semantic versioning rules: `major.minor.patch` (e.g., `2.0.2` vs `2.0.3`)
+   - An update is available if the remote version is **greater than** the current version
+   - Examples:
+     - Current: `2.0.2` → Remote: `2.0.3` ✅ Update available
+     - Current: `2.0.2` → Remote: `2.0.2` ❌ No update (same version)
+     - Current: `2.0.3` → Remote: `2.0.2` ❌ No update (current is newer)
+     - Current: `2.0.2b` → Remote: `2.0.3` ✅ Update available (prerelease tags are handled)
+
+4. **Version Format Handling**:
+   - **Semantic versions** (e.g., `1.0.0`, `2.1.3`) are compared numerically
+   - **Prerelease versions** (e.g., `2.0.2b`, `2.0.2-beta`) are compared with special handling
+   - **Non-semantic versions** may cause issues - it's recommended to use semantic versioning
+
+### Update Metadata Files
+
+When you build and publish a release, electron-builder generates platform-specific metadata files:
+
+**Windows/Linux** (`latest.yml`):
+```yaml
+version: 2.0.3
+files:
+  - url: Hytale-F2P-Launcher-2.0.3-x64.exe
+    sha512: abc123...
+    size: 12345678
+path: Hytale-F2P-Launcher-2.0.3-x64.exe
+sha512: abc123...
+releaseDate: '2024-01-15T10:30:00.000Z'
+```
+
+**macOS** (`latest-mac.yml`):
+```yaml
+version: 2.0.3
+files:
+  - url: Hytale-F2P-Launcher-2.0.3-arm64-mac.zip
+    sha512: def456...
+    size: 23456789
+path: Hytale-F2P-Launcher-2.0.3-arm64-mac.zip
+sha512: def456...
+releaseDate: '2024-01-15T10:30:00.000Z'
+```
+
+These files are:
+- Automatically generated during build
+- Uploaded to GitHub Releases
+- Fetched by electron-updater to check for updates
+- Used to determine if an update is available and what to download
+
+### The Check Process in Detail
+
+When `appUpdater.checkForUpdatesAndNotify()` is called:
+
+1. **Read Current Version**: Gets version from `app.getVersion()` (which reads from `package.json`)
+2. **Fetch Update Info**: 
+   - Makes HTTP request to GitHub Releases API or reads `latest.yml`
+   - Gets the version number from the metadata
+3. **Compare Versions**: 
+   - Uses semantic versioning comparison (e.g., `semver.gt(remoteVersion, currentVersion)`)
+   - If remote > current: update available
+   - If remote <= current: no update
+4. **Emit Events**: 
+   - `update-available` if newer version found
+   - `update-not-available` if already up to date
+5. **Download if Available**: If `autoDownload` is enabled, starts downloading automatically
+
+### Example Flow
+
+```
+App Version: 2.0.2 (from package.json)
+                ↓
+Check GitHub Releases API
+                ↓
+Latest Release: 2.0.3
+                ↓
+Compare: 2.0.3 > 2.0.2? YES
+                ↓
+Emit: 'update-available' event
+                ↓
+Download update automatically
+                ↓
+Emit: 'update-downloaded' event
+                ↓
+User can install on next restart
+```
+
+## Components
+
+### AppUpdater Class (`backend/appUpdater.js`)
+
+The main class that handles all update operations:
+
+- **`checkForUpdatesAndNotify()`**: Checks for updates and shows a system notification if available
+- **`checkForUpdates()`**: Manually checks for updates (returns a promise)
+- **`quitAndInstall()`**: Quits the app and installs the downloaded update
+
+### Events
+
+The AppUpdater emits the following events that the UI can listen to:
+
+- `update-checking`: Update check has started
+- `update-available`: A new update is available
+- `update-not-available`: App is up to date
+- `update-download-progress`: Download progress updates
+- `update-downloaded`: Update has finished downloading
+- `update-error`: An error occurred during the update process
+
+## Configuration
+
+### Package.json
+
+The publish configuration in `package.json` tells electron-builder where to publish updates:
+
+```json
+"publish": {
+  "provider": "github",
+  "owner": "amiayweb",
+  "repo": "Hytale-F2P"
+}
+```
+
+This means updates will be fetched from GitHub Releases for the `amiayweb/Hytale-F2P` repository.
+
+## Publishing Updates
+
+### For Developers
+
+1. **Update Version**: Bump the version in `package.json` (e.g., `2.0.2b` → `2.0.3`)
+
+2. **Build the App**: Run the build command for your platform:
+   ```bash
+   npm run build:win    # Windows
+   npm run build:mac    # macOS
+   npm run build:linux  # Linux
+   ```
+
+3. **Publish to GitHub**: When building with electron-builder, it will:
+   - Generate update metadata files (`latest.yml`, `latest-mac.yml`, etc.)
+   - Upload the built files to GitHub Releases (if configured with `GH_TOKEN`)
+   - Make them available for auto-update
+
+4. **Release on GitHub**: Create a GitHub Release with the new version tag
+
+### Important Notes
+
+- **macOS Code Signing**: macOS apps **must** be code-signed for auto-updates to work
+- **Version Format**: Use semantic versioning (e.g., `1.0.0`, `2.0.1`) for best compatibility
+- **Update Files**: electron-builder automatically generates the required metadata files (`latest.yml`, etc.)
+
+## Testing Updates
+
+### Development Mode
+
+To test updates during development, create a `dev-app-update.yml` file in the project root:
+
+```yaml
+owner: amiayweb
+repo: Hytale-F2P
+provider: github
+```
+
+Then enable dev mode in the code:
+```javascript
+autoUpdater.forceDevUpdateConfig = true;
+```
+
+### Local Testing
+
+For local testing, you can use a local server (like Minio) or a generic HTTP server to host update files.
+
+## User Experience
+
+### What Users See
+
+1. **On Startup**: The app silently checks for updates in the background
+2. **Update Available**: A notification appears if an update is found
+3. **Downloading**: Progress bar shows download status
+4. **Ready to Install**: User is notified when the update is ready
+5. **Installation**: Update installs on app restart or when user clicks "Install Now"
+
+### User Actions
+
+- Users can manually check for updates through the settings/update menu
+- Users can choose to install immediately or wait until next app launch
+- Users can continue using the app while updates download in the background
+
+## Troubleshooting
+
+### Updates Not Working
+
+1. **Check GitHub Releases**: Ensure releases are published on GitHub
+2. **Check Version**: Make sure the version in `package.json` is higher than the current release
+3. **Check Logs**: Check the app logs for update-related errors
+4. **Code Signing (macOS)**: Verify the app is properly code-signed
+
+### Common Issues
+
+- **"Update not available"**: Version in `package.json` may not be higher than the current release
+- **"Download failed"**: Network issues or GitHub API rate limits
+- **"Installation failed"**: Permissions issue or app is running from an unsupported location
+
+## Technical Details
+
+### Supported Platforms
+
+- **Windows**: NSIS installer (auto-update supported)
+- **macOS**: DMG + ZIP (auto-update supported, requires code signing)
+- **Linux**: AppImage, DEB, RPM, Pacman (auto-update supported)
+
+### Update Files Generated
+
+When building, electron-builder generates:
+- `latest.yml` (Windows/Linux)
+- `latest-mac.yml` (macOS)
+- `latest-linux.yml` (Linux)
+
+These files contain metadata about the latest release and are automatically uploaded to GitHub Releases.

+# Clearing Electron-Updater Cache
+
+To force electron-updater to re-download an update file, you need to clear the cached download.
+
+## Quick Method (Terminal)
+
+### macOS
+```bash
+# Remove the entire cache directory
+rm -rf ~/Library/Caches/hytale-f2p-launcher
+
+# Or just remove pending downloads
+rm -rf ~/Library/Caches/hytale-f2p-launcher/pending
+```
+
+### Windows
+```bash
+# Remove the entire cache directory
+rmdir /s "%LOCALAPPDATA%\hytale-f2p-launcher-updater"
+
+# Or just remove pending downloads
+rmdir /s "%LOCALAPPDATA%\hytale-f2p-launcher-updater\pending"
+```
+
+### Linux
+```bash
+# Remove the entire cache directory
+rm -rf ~/.cache/hytale-f2p-launcher-updater
+
+# Or just remove pending downloads
+rm -rf ~/.cache/hytale-f2p-launcher-updater/pending
+```
+
+## Cache Locations
+
+electron-updater stores downloaded updates in:
+
+- **macOS**: `~/Library/Caches/hytale-f2p-launcher/`
+- **Windows**: `%LOCALAPPDATA%\hytale-f2p-launcher-updater\`
+- **Linux**: `~/.cache/hytale-f2p-launcher-updater/`
+
+The cache typically contains:
+- `pending/` - Downloaded update files waiting to be installed
+- Metadata files about available updates
+
+## After Clearing
+
+After clearing the cache:
+1. Restart the launcher
+2. It will check for updates again
+3. The update will be re-downloaded from scratch
+
+## Programmatic Method
+
+You can also clear the cache programmatically by adding this to your code:
+
+```javascript
+const { autoUpdater } = require('electron-updater');
+const path = require('path');
+const fs = require('fs');
+const os = require('os');
+
+function clearUpdateCache() {
+  const cacheDir = path.join(
+    os.homedir(),
+    process.platform === 'win32' 
+      ? 'AppData/Local/hytale-f2p-launcher-updater'
+      : process.platform === 'darwin'
+      ? 'Library/Caches/hytale-f2p-launcher'
+      : '.cache/hytale-f2p-launcher-updater'
+  );
+  
+  if (fs.existsSync(cacheDir)) {
+    fs.rmSync(cacheDir, { recursive: true, force: true });
+    console.log('Update cache cleared');
+  }
+}

+# Testing Auto-Updates
+
+This guide explains how to test the auto-update system during development.
+
+## Quick Start
+
+### Option 1: Test with GitHub Releases (Easiest)
+
+1. **Set up dev-app-update.yml** (already done):
+   ```yaml
+   provider: github
+   owner: amiayweb
+   repo: Hytale-F2P
+   ```
+
+2. **Lower your current version** in `package.json`:
+   - Change version to something lower than what's on GitHub (e.g., `2.0.1` if GitHub has `2.0.3`)
+
+3. **Run the app in dev mode**:
+   ```bash
+   npm run dev
+   # or
+   npm start
+   ```
+
+4. **The app will check for updates** 3 seconds after startup
+   - If a newer version exists on GitHub, it will detect it
+   - Check the console logs for update messages
+
+### Option 2: Test with Local HTTP Server
+
+For more control, you can set up a local server:
+
+1. **Create a test update server**:
+   ```bash
+   # Create a test directory
+   mkdir -p test-updates
+   cd test-updates
+   ```
+
+2. **Build a test version** with a higher version number:
+   ```bash
+   # In package.json, set version to 2.0.4
+   npm run build
+   ```
+
+3. **Copy the generated files** to your test server:
+   - Copy `dist/latest.yml` (or `latest-mac.yml` for macOS)
+   - Copy the built installer/package
+
+4. **Start a simple HTTP server**:
+   ```bash
+   # Using Python
+   python3 -m http.server 8080
+   
+   # Or using Node.js http-server
+   npx http-server -p 8080
+   ```
+
+5. **Update dev-app-update.yml** to point to local server:
+   ```yaml
+   provider: generic
+   url: http://localhost:8080
+   ```
+
+6. **Run the app** and it will check your local server
+
+## Testing Steps
+
+### 1. Prepare Test Environment
+
+**Current version**: `2.0.3` (in package.json)
+**Test version**: `2.0.4` (on GitHub or local server)
+
+### 2. Run the App
+
+```bash
+npm run dev
+```
+
+### 3. Watch for Update Events
+
+The app will automatically check for updates 3 seconds after startup. Watch the console for:
+
+```
+Checking for updates...
+Update available: 2.0.4
+```
+
+### 4. Check Console Logs
+
+Look for these messages:
+- `Checking for updates...` - Update check started
+- `Update available: 2.0.4` - New version found
+- `Download speed: ...` - Download progress
+- `Update downloaded: 2.0.4` - Download complete
+
+### 5. Test UI Integration
+
+The app sends these events to the renderer:
+- `update-checking`
+- `update-available` (with version info)
+- `update-download-progress` (with progress data)
+- `update-downloaded` (ready to install)
+
+You can listen to these in your frontend code to show update notifications.
+
+## Manual Testing
+
+### Trigger Manual Update Check
+
+You can also trigger a manual check via IPC:
+```javascript
+// In renderer process
+const result = await window.electronAPI.invoke('check-for-updates');
+console.log(result);
+```
+
+### Install Update
+
+After an update is downloaded:
+```javascript
+// In renderer process
+await window.electronAPI.invoke('quit-and-install-update');
+```
+
+## Testing Scenarios
+
+### Scenario 1: Update Available
+1. Set `package.json` version to `2.0.1`
+2. Ensure GitHub has version `2.0.3` or higher
+3. Run app → Should detect update
+
+### Scenario 2: Already Up to Date
+1. Set `package.json` version to `2.0.3`
+2. Ensure GitHub has version `2.0.3` or lower
+3. Run app → Should show "no update available"
+
+### Scenario 3: Prerelease Version
+1. Set `package.json` version to `2.0.2b`
+2. Ensure GitHub has version `2.0.3`
+3. Run app → Should detect update (prerelease < release)
+
+## Troubleshooting
+
+### Update Not Detected
+
+1. **Check dev-app-update.yml exists** in project root
+2. **Verify dev mode is enabled** - Check console for "Dev update mode enabled"
+3. **Check version numbers** - Remote version must be higher than current
+4. **Check network** - App needs internet to reach GitHub/local server
+5. **Check logs** - Look for error messages in console
+
+### Common Errors
+
+- **"Cannot find module 'electron-updater'"**: Run `npm install`
+- **"Update check failed"**: Check network connection or GitHub API access
+- **"No update available"**: Version comparison issue - check versions
+
+### Debug Mode
+
+Enable more verbose logging by checking the console output. The logger will show:
+- Update check requests
+- Version comparisons
+- Download progress
+- Any errors
+
+## Testing with Real GitHub Releases
+
+For the most realistic test:
+
+1. **Create a test release on GitHub**:
+   - Build the app with version `2.0.4`
+   - Create a GitHub release with tag `v2.0.4`
+   - Upload the built files
+
+2. **Lower your local version**:
+   - Set `package.json` to `2.0.3`
+
+3. **Run the app**:
+   - It will check GitHub and find `2.0.4`
+   - Download and install the update
+
+## Notes
+
+- **Dev mode only works when app is NOT packaged** (`!app.isPackaged`)
+- **Production builds** ignore `dev-app-update.yml` and use the built-in `app-update.yml`
+- **macOS**: Code signing is required for updates to work in production
+- **Windows**: NSIS installer is required for auto-updates
+
+## Next Steps
+
+Once testing is complete:
+1. Remove or comment out `forceDevUpdateConfig` for production
+2. Ensure proper code signing for macOS
+3. Set up CI/CD to automatically publish releases
