Release v3.9.8 adds Google, Facebook, and GitHub social login for onboarding while improving auto‑resume logic to recover transfers on unstable networks.

Why it matters: Social login (id 28835) expands user acquisition; enhanced network resilience (id 28836, severity 40) reduces transfer failures under flaky connections.

Full changelog

🚀 What's New in v3.9.8

This update focuses on making ffl easier to access for new users and ensuring even greater persistence when dealing with spotty network conditions.

🔐 Seamless Onboarding (Social Logins)

Google, Facebook, & GitHub Support: We've drastically streamlined the registration process. You can now instantly claim a free account or sign in using your existing Google, Facebook, or GitHub credentials. Getting started with ffl is now faster and frictionless!

⚡ Enhanced Network Resilience

Aggressive Auto-Resume: We've upgraded how ffl handles poor connections. When the network becomes highly unstable or drops unexpectedly, the transfer engine will now try much harder to automatically recover and resume the transfer before giving up, ensuring your data gets across even on the most unreliable networks.

🐛 Bug Fixes & Polish

Cleaner Tunnel Logs: Silenced noisy TimeoutError tracebacks that could clutter the terminal during momentary tunnel connection issues. The console output now remains clean, readable, and professional even when the underlying network is struggling.

Windows (native)

x86_64 → ffl-v3.9.8-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+ — smaller & faster
- ffl-v3.9.8-manylinux_glibc2.39-x86_64-linux.tar.gz
- Best for newer distros (e.g., Ubuntu 24).
glibc 2.28+ — widest compatibility
- ffl-v3.9.8-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) → ffl-v3.9.8-aarch-darwin.tar.gz
Intel (x86_64) → ffl-v3.9.8-x86_64-darwin.tar.gz

The archive unpacks to a single ffl binary.

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

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

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