cURL Import & SwiftNIO Migration

Full cURL command import with an in-process runtime, and a ground-up rewrite of the networking stack on SwiftNIO and AsyncHTTPClient.

Added
  • cURL command import with analyzer-driven execution and multi-transfer planning
  • In-process curl runtime with mbedTLS-backed TLS and HTTP/2 via nghttp2
  • Permission-aware import outcomes with local-network retry heuristics
  • UDP PCAP analysis and hardened flow capture lifecycle
  • Duplicate detection and editor diagnostics in the UI
  • Capture cleanup actions and resilient auto-load fallback
Improved
  • Migrated certificate handling to swift-certificates and compression to libzstd
  • Request executor and networking rewritten on AsyncHTTPClient
  • SOCKS5 and UDP forwarding migrated to NIO Transport Services
  • MITM proxy internals rebuilt on NIO channel pipelines
  • Removed legacy protocol parsers and curl runtime
Fixed
  • cURL parser handling of line continuations after quoted arguments
  • Failed transfers no longer block cURL import completion
  • Request duration now renders above size in list rows
  • Input-specific keyboard types applied across all UI forms
  • Zstd single-chunk streaming decode now flushes completed frames
  • Captured bytes retained for truncated response bodies
  • SOCKS5 UDP setup hardened with normalized full-tunnel config
  • MITM CONNECT and streaming proxy pipeline stabilized
  • PCAP writes batched to avoid duplicate full-tunnel capture
  • Tunnel shutdown paths synchronized with tighter redirect handling

SOCKS5 Fallback & Widgets

Embedded local SOCKS5 fallback for environments without VPN tunneling, privacy-safe widget labels, and UX refinements across share sheets and toasts.

Added
  • Local SOCKS5 fallback embedded for environments where VPN tunneling is unavailable
  • Privacy-safe widget labels with deep-link tab navigation
  • Clear-all confirmation alerts across network and rule list views
  • Notification permission prompt moved from onboarding to settings
Improved
  • Body inspector extracted with cleaner action and view-model structure
Fixed
  • Share sheet presented directly to avoid blank host canvas
  • Active session durations now tick correctly with clamped negative times
  • Chunked and compressed SSE streams decoded with live snapshot persistence
  • Stray menu dividers removed from rule list views
  • Toast sized to content with centered text

IPv6, Widgets & Stability

IPv6 VPN capture, App Shortcuts and Control Center integration, settings reorganization, and a major stability pass across compression, PCAP, and concurrency.

Added
  • IPv6 support for VPN capture and VPN log export
  • App Shortcuts and Siri intents for widget and Control Center integration
  • Standardized empty states with primary actions across all list views
  • DNS change notifications with optimized message handling
  • Script execution timeouts and improved debugging output
  • PCAP packet processing with granular error handling
Improved
  • Settings reorganized into dedicated capture, rules, and security pages
  • Accessibility and design consistency refined across all views
  • Chunked body decoding and SSE handler state management rewritten
  • Decompression errors unified with consolidated decoding paths
  • Script execution counts and rewrite rule stats batched for performance
Fixed
  • Breakpoint resume race condition with hardened cURL import/export
  • Validation and pattern matching edge cases tightened
  • VPN tunnel lifecycle serialized to prevent duplicate concurrent starts
  • Per-domain certificate storage and ClientHello parsing hardened
  • Compression stream finalization with no-progress loop prevention
  • Redirect loop prevention with bounded PCAP capture
  • Big-endian PCAP support with overlapping TCP segment draining
  • Filtered items now sort by timestamp
  • Brotli and Deflate stream end validation
  • Swift 6 strict concurrency compile errors resolved

Capture Controls

Advanced capture controls with persistent settings and a fix for unintended capture toggles during settings restore.

Added
  • Advanced capture controls with persistent settings
Fixed
  • Settings restore no longer triggers unintended capture toggles
