New Features:

🚫 User Blocking: you can block users from DMs - blocked contacts are hidden from contacts, invites, and notifications

👤 Profile Invites: share your own profile online with a single tap via the new Share button

🔐 Memory-Hardened Key Vault: private keys are XOR-split into 4 shares scattered across 128 indistinguishable decoy arrays — invisible to malware & forensics

📋 Unified Logging: new structured logging system with UTC timestamps, error toasts, and a persistent log file for easier debugging

🪂 Error Logging: errors are now caught and written to a private crash log — with a Copy Logs button in Settings for easy bug reports

Improvements:

🔋 Android Battery Life: background sync now connects to a single relay (with automatic failover) instead of 4-5, eliminating ~75% of radio wakeups

🎮 Mini App Realtime Overhaul: rebuilt WebXDC realtime channels with preconnect, SQLite persistence, message buffering, and bi-directional WebSocket support

🚀 Windows Mini App Performance: dramatically improved WebGL/WASM performance for Mini Apps on Windows

🛡️ Anti-Debug Protections: release builds block debugger attachment, memory inspection, and unsigned DLL injection across macOS, Linux, Android, and Windows

🧹 Zeroize Everywhere: passwords, seeds, nsec strings, and temporary key copies are wiped from memory immediately after use via volatile writes

📡 Scoped MLS Subscriptions: group message subscriptions are now filtered by your group IDs at the relay level

⚡ Instant Background Stop: background sync now uses zero-cost Notify signaling instead of polling every 5 seconds, responding instantly when you open the app

Fixes:

👻 Ghost Messages: MLS group messages no longer visually duplicate — the relay echo is now deduplicated at the backend before reaching the UI

📱 Android Foreground Resume: opening the app after background sync no longer shows an empty UI or login screen — stale relay connections and partial state are cleaned up automatically

🖼️ Preview Image Crash: fixed crash when a link preview’s og:image URL fails to load

🎮 Mini App Session Fix: fixed Android Mini App failing to connect on second session open

🔍 GIF Search Safety: GIF search empty state no longer interpolates user input as HTML

📎 Mini App Upload Spinner: fixed duplicate progress spinners and spinner overlapping text in chat bubbles
