Changelog

v2.0.0

Home Screen — Added a new landing screen with typewriter hero text, pigeon logo, and Hotspot/WiFi mode selection
QR Code Scanning — CameraX + ZXing-based QR code scanner for quick peer pairing
QR Code Generation — Generate QR codes to share connection details
Wi-Fi Hotspot Direct Share — Android LocalOnlyHotspot manager for programmatic hotspot creation, enabling transfers without an existing WiFi network
Embedded HTTP File Server — Pure Java ServerSocket-based HTTP file server serves files over the hotspot for browser-based downloads
Hotspot Share Screen — File picker, hotspot credentials display, and QR code sharing in a single screen
Curtain Transition Animation — Samsung One UI "Now Bar" style curtain reveal transition component
Stacked Swipe Mode Selector — Animated stacked swipe pill component with AGSL liquid metal shader effect for switching between Send and Receive modes

Buffered Network I/O — Added 2MB buffered reader/writer on both sender and receiver sides to aggregate writes into fewer, larger TLS records, reducing encryption overhead
Buffered File Writing — Receiver now wraps destination files in a 256KB buffered writer, with explicit flush at completion
File Pre-allocation — Received files are pre-allocated on disk (seek to Size-1) to prevent filesystem fragmentation and incremental allocation during transfer
Per-Connection TLS — Moved from tls.Listen/tls.Dial to raw TCP with explicit per-connection tls.Server/tls.Client handshakes; cipher suites now explicitly prefer AES-GCM over ChaCha20 for hardware AES-NI acceleration
TCP Socket Tuning — TCP_NODELAY enabled, read/write socket buffers increased to 2MB
Reduced Allocations — ChunkedWriter now uses a reusable [4]byte header buffer instead of allocating make([]byte, ...) on every write

Fixed goroutine leak in ScanPeers() — The entries channel from the mDNS resolver is now explicitly closed when the scan context expires, preventing ScanPeers from blocking indefinitely
Fixed data race in history loading — loadHistory() now creates a defensive copy of the entries slice before returning, preventing race conditions between concurrent Wails JSON serialization and addHistoryEntry writes
