🔒 Core Principle Change: Zero Ads and Tracking

The most significant change is our commitment to a truly private experience:

  • 🚫 Complete Ad Removal: We have permanently eliminated all third-party ads and advertising tracking of any kind.
  • 🧘 Distraction-Free Search: Search is now optimized for speed and focus, with the distraction-free mode enabled by default.

⚡ Performance & Stability: Upgrading the Core Engine

We’ve integrated the new jlibtorrent 2.0.12.7, bringing hundreds of bug fixes and next-generation features:

New Features

  • BitTorrent v2 Protocol Support: Full support for the modern v2 and hybrid v1/v2 protocols.
  • New Search Sources: Added Knaben and TorrentCSV search performers for more results.
  • Flexible Port Selection: New setting: Settings > Torrent Settings > Incoming Connection Port Range selection.
  • Automatic Seeding: Finished HTTP transfers are now seeded automatically if seeding is enabled (matching desktop functionality).

Major Performance Optimizations

  • Architectural Overhaul: Achieved a 25-50% reduction in memory allocations and significantly reduced garbage collection pressure.
  • Blazing Fast Search: Search sorting has been optimized from $O(n^2 \log n)$ to $O(n \log n)$.
  • 8.8x Speed Gains: Title normalization and cleaning is now dramatically faster by eliminating heavy regular expressions.
  • Efficient I/O: CPU usage during disk I/O operations is reduced by 30-50% (up to 96% in system write calls) by using buffered I/O.

Critical Crash & Freeze Fixes

  • Eliminated ANR Crashes: Fixed numerous ANR (Application Not Responding) crashes in the Transfers list, menu preparation, and playback services by moving blocking tasks to background threads.
  • Network API Migration: Fixed critical issues with VPN Guard and Wi-Fi-Only protection by migrating from deprecated network APIs to the modern NetworkCallback API.
    • VPN Guard: Now correctly stops torrents when a VPN is required but not connected.
    • Wi-Fi-Only: Correctly pauses torrent downloads on mobile data.
  • Protection Visuals: Added visual status indicators in the transfers screen to show when protections pause downloads.

🔧 Maintenance & Library Upgrades

We’ve updated the entire internal technology stack for security and modern compatibility:

  • Image Loading: Replaced the older Picasso library with the modern Coil image loading library.
  • Library Updates: Updated Kotlin, Gradle, OkHttp, and many core AndroidX libraries.
  • Removal of Dead Performers: Removed the TorrentDownloads, BTDigg, Torlock, and LimeTorrents search performers due to being permanently offline or unreliable.
  • jlibtorrent Updates: Upgraded to jlibtorrent 2.0.x with C++20 compilation, OpenSSL 3.5.2, and Boost 1.88.0.

This update ensures FrostWire is faster, more stable, more private, and ready for years to come!
