BATorrent 4.1.0

BATorrent is a lightweight, open-source BitTorrent client built with modern C++ and Qt 6, offering a clean, fast, and privacy-focused alternative to traditional torrent apps. It supports magnet links, .torrent files, resume data, sequential downloading, per-file priorities, and even imports from qBittorrent. Power users benefit from integrated RSS auto-download with regex filtering, duplicate detection, and automatic tracker lists from Stremio. Streaming is seamless thanks to auto-detected players like VLC and IINA.

BATorrent includes robust VPN tools—interface binding, auto-detection for WireGuard-based services like Mullvad and NordLynx, kill switch, proxy support, and IP filtering. A full WebUI enables remote control, while integrations with Plex, Jellyfin, and Emby automate library updates. With themes, speed scheduling, system-tray alerts, and cross-platform support for Windows, Linux, and macOS, BATorrent delivers a polished, high-performance torrenting experience.

BATorrent 4.1.0 release notes:

• A community-driven release: everything here came straight from your reports and requests. It closes the remaining gaps with qBittorrent and fixes the Windows settings/tray/splash issues several of you hit.

Fixed

• Settings now actually save. A whole class of preferences — speed limits (and the alternative limits), max active downloads, seed ratio, listen port, max connections, DHT/uTP/encryption, VPN interface, kill switch and proxy — weren't being persisted and reset to defaults on every launch. They now round-trip correctly. (Thanks to everyone who reported "the upload limit always goes back to 0".)
• Splash and tray toggles stick on Windows. Turning off the startup animation (or "close to tray") no longer reverts — the Windows registry stored these booleans as integers and the UI was misreading them.
• Close-to-tray hint. The first time the window hides to the tray you get a one-time notification, so the app doesn't look like it vanished (Windows 11 tucks new tray icons into the overflow).
• macOS Dock icon size. The icon filled its canvas edge-to-edge and rendered larger than neighbouring apps; it now uses the standard safe-area padding.
• Native file picker language. The "Torrent file / All files" filter in the open dialog follows the app language instead of being hard-coded.

Added — qBittorrent parity

• Alternative speed limits toggle — a turtle button in the toolbar flips your throttled limits on/off instantly, independent of the scheduler.
• Follow system theme — switch light/dark automatically with the OS (Settings → Appearance).
• Pre-allocate disk space — reserve the full file size up front to reduce fragmentation (Settings → Downloads).
• Recheck data on add — optionally force a hash check when adding a torrent, so existing or partial files on disk are detected.
• Port status indicator — a 🔴 dot in the status bar shows whether your listen port looks reachable (UPnP/NAT-PMP + listen state; fully local, no external check).
• Add torrent from URL — File → Add torrent from URL (Ctrl+U) fetches a remote .torrent and routes it through the normal add dialog.
• Export .torrent — right-click a torrent → Export .torrent to save its metadata file.

Already there (in case you missed it)

• Watch folder — auto-add .torrent files dropped into a monitored directory (Settings → Files). This release just surfaces it.
• Incomplete files already carry a .!bt suffix until they finish.

Under the hood

• Regression tests for the settings-persistence and Windows boolean bugs.
• A new Qt Quick Test harness covering the startup splash and the design-system widgets.
