Release v1.2.0

Version 1.2.0 (2025-10-25)

Major Improvements

🌐 IANA RDAP Bootstrap Integration

• Implemented official IANA RDAP bootstrap service for universal TLD support
• Three-tier lookup strategy:
  1. Hardcoded servers for top 25 TLDs (instant lookup)
  2. Cached IANA data for previously queried TLDs (fast lookup)
  3. Dynamic IANA fetch for new TLDs (comprehensive coverage)

📦 Smart Caching System

• IANA bootstrap data cached in localStorage for 7 days
• Automatic cache refresh when expired
• Reduces network requests and improves performance
• ~1,500+ TLDs supported automatically

🚀 Performance Optimizations

• Top 25 most popular TLDs hardcoded for zero-latency lookups:
  • Generic: .com, .net, .org, .info, .biz
  • New gTLDs: .io, .ai, .co, .me, .xyz, .online, .dev, .app, .cloud, .tech
  • Country codes: .uk, .de, .cn, .nl, .fr, .au, .ca, .jp, .br, .it, .es, .ru, .in
• RDAP servers selected based on official IANA registry
• Console logging for debugging and transparency

Technical Details

RDAP Lookup Priority

1. Check hardcoded bootstrap (instant)
   ↓ if not found
2. Check IANA cache (fast)
   ↓ if not found or expired
3. Fetch IANA bootstrap (comprehensive)
   ↓ if still not found
4. Fallback to WHOIS API

What Changed

• RegistryDetector: Now queries IANA's official RDAP bootstrap service
• RdapClient: Updated to use async RDAP URL resolution
• Lookup Logic: Properly awaits RDAP support checks before routing
• Error Handling: Improved fallback chain with better logging

Why This Matters

• Universal Coverage: Supports virtually all TLDs with RDAP servers
• Always Up-to-Date: IANA registry is the authoritative source
• Better Privacy: More lookups use RDAP (faster, more private than WHOIS)
• Reliability: Smart fallback ensures lookups always work
