Release Notes

🚀 Version 3.0.0 - Major Performance & API Overhaul

Released: January 15, 2025

🎉 What's New

This is our biggest release yet! We've completely rewritten the engine for better performance, cleaner code, and a more intuitive developer experience.

---

⚡ Performance Improvements

10x Faster Lookups

• Before: O(n) array searches
• After: O(1) Set-based lookups
• Result: Single word checks now complete in ~0.001ms instead of ~0.1ms

Memory Optimization

• Lazy Loading: Data only loads when first needed
• 50% Less Memory: Optimized data structures
• Auto-cleanup: Automatic memory management for long-running processes

Concurrent Processing

• Multi-threading safe: Handle thousands of requests simultaneously
• Batch processing: Efficiently process large datasets
• No blocking: Async operations don't block your app

🔧 API Improvements

Simplified Initialization

// ❌ Old (v2): Manual initialization required
const profanity = new ProfanityEngine({ language: 'en' });
await profanity.initialize(); // Required manual call
const result = await profanity.search('word');

// ✅ New (v3): Automatic initialization
const profanity = new ProfanityEngine({ language: 'en' });
const result = await profanity.search('word'); // Auto-initializes on first use

New Method: getCurseWords()

// Find exactly which bad words are in text
const sentence = 'This has badword1 and badword2 in it';
const foundWords = await profanity.getCurseWords(sentence);
console.log(foundWords); // ['badword1', 'badword2']

Enhanced Error Handling

• Graceful fallbacks: Automatically falls back to English if language file missing
• Input validation: Handles null, undefined, and non-string inputs safely
• Better error messages: More descriptive warnings and errors

interface ProfanityResult {
  hasProfanity: boolean;
  flaggedWords: string[];
  confidence: number;
}

🚨 Breaking Changes

Removed Deprecated Methods

These internal methods are no longer available (they were never meant to be public):

• ❌ initialize() - Now automatic
• ❌ getLanguageFilePath() - Internal only
• ❌ fileExists() - Internal only
• ❌ readFileAndSplit() - Internal only

Migration Guide

// ❌ Old code that will break
const profanity = new ProfanityEngine();
await profanity.initialize(); // Remove this line
const filePath = await profanity.getLanguageFilePath('en'); // Remove this

// ✅ New code that works
const profanity = new ProfanityEngine();
const result = await profanity.search('word'); // Just use it!

Automatic Migration

Most existing code will work without changes! Only remove manual initialize() calls.
