LibreFang 0.6.4 Released

We're excited to announce LibreFang v0.6.4 — another solid update to your open-source Agent Operating System! This release brings new LLM providers, important stability improvements, and a fresh coat of paint. Let's dive in.

What's New

Expanded LLM Support

LibreFang now supports Qwen Code CLI as a new LLM provider (#1224), giving you even more options for powering your agents. We also aligned the init defaults with OpenRouter Stepfun (#1262), so new users get better out-of-the-box configuration.

Image Pipeline & Subprocess Management

The new image pipeline and subprocess management feature (#1223) enables richer agent capabilities — think image processing workflows and better control over external tool execution.

Fresh Visual Identity

We replaced all icons with new LibreFang branding (#1263), giving the project a more cohesive and professional look. It's the same great functionality, now easier on the eyes.

Stability & Security

Web Deployment Overhaul

This release tackles a long-standing issue: web deployment reliability. We landed multiple fixes (#1236, #1237, #1238, #1239, #1243) that should make deploying and running the web interface much smoother. If you've had trouble with web deployment before, this update is for you.

Hardened Install Flow

The one-line install script (curl -fsSL https://get.librefang.ai | sh) got a security hardening pass (#1259). We also addressed code-scanning path-injection findings (#1260) — small things that make a big difference for security-conscious deployments.

Bug Fixes

• Fixed web UI chat input line break issue (#1245) — no more broken messages
• Repaired the install smoke script and dropped an outdated workflow (#1255)

Developer Experience

Better Documentation

SDK usage examples now appear in all README files (#1229), so whether you're using Rust, JavaScript, or Python, you'll find clear guidance getting started.

Infrastructure Improvements

• Added .nvmrc for web Node.js version consistency (#1234)
• Fixed Dockerfile path issues (#1234)
