Full changelog

πŸš€ What's New in v3.9.11

This release brings powerful new customization options for professionals, deep desktop OS integration for lightning-fast sharing, and a significantly improved gallery viewing experience.

🎨 Custom Branding & Identity

  • Unified Brand Experience: You can now fully customize your web download pages to match your brand! ffl now fully synchronizes all custom branding settings and configurations seamlessly between the client and the server.
  • Want to set up your own logo, colors, and layout? Check out our complete Branding Tutorial.

πŸ–±οΈ OS Context Menu Integration

  • Right-Click to Share: We've introduced native system context menu support! By running the new command ffl shell --install (and --uninstall to remove), you can integrate ffl directly into your operating system's right-click menu.
  • This allows you to instantly right-click any file on your desktop and quickly choose from standard sharing, single-download restrictions, or End-to-End Encrypted sharing without ever opening a terminal.

πŸ–ΌοΈ Web Preview Upgrades

  • Gallery Navigation: Browsing folders just got much smoother. You can now use your keyboard's Left/Right arrow keys to quickly flip through previewable files. We've also added intuitive < and > navigation buttons directly to the Web UI.
  • Optimized Video Player: Fixed an issue regarding the default display dimensions of the video player in the preview mode. Videos now load at a much more comfortable, natural viewing size.

πŸ› Bug Fixes & Stability

  • Seamless Windows Upgrades: Fixed an issue where the upgrade command would fail on Windows. Previously, the system could not overwrite the currently running executable to complete the update process. ffl now handles self-replacement on Windows flawlessly.

Windows (native)

  • x86_64 β†’ ffl-v3.9.11-x86_64-windows.zip
    Unzip to get ffl.exe.

Linux (native)

We publish two glibc baselines. Pick the highest baseline that does not exceed your system glibc:

  • glibc 2.39+ β€” smaller & faster

    • ffl-v3.9.11-manylinux_glibc2.39-x86_64-linux.tar.gz
    • Best for newer distros (e.g., Ubuntu 24).
  • glibc 2.28+ β€” widest compatibility

    • ffl-v3.9.11-manylinux_glibc2.28-x86_64-linux.tar.gz
    • Works on older distros (e.g., Ubuntu 20); larger due to additional internal linking.

⚠️ If your system is musl-based (e.g., Alpine) or you’re unsure about glibc, prefer APE ffl.com.

macOS (native)

  • Apple Silicon (arm64) β†’ ffl-v3.9.11-aarch-darwin.tar.gz
  • Intel (x86_64) β†’ ffl-v3.9.11-x86_64-darwin.tar.gz

The archive unpacks to a single ffl binary.

🧰 APE (cross-platform single file, zero external deps)

  • ffl.com β€” Single-file build that runs natively on Linux, macOS, Windows, FreeBSD, OpenBSD 7.3, NetBSD, BIOS, and Android (Termux).
  • fflo.com β€” Alternative APE build that is exactly aligned with the open-source repo (no additional/proprietary addons).
    As a result, features that require closed-source componentsβ€”such as upload to server (e.g., --upload)β€”are not available.

For a deeper comparison between native and APE, see the README’s notes.
