Breaking Changes

License Upgrade: AGPL → Apache 2.0

This is a significant milestone for the Feat project. We have upgraded our open source license from AGPL to Apache 2.0, providing a more business-friendly environment for enterprises and developers.

Why the License Change?

Since its inception in December 2024, the Feat project has experienced rapid development and iteration. Initially, we chose the AGPL license to protect the integrity of the open source project. However, as the project matured, we recognized that the "viral" nature of AGPL posed significant legal risks for enterprise users, becoming a major barrier to Feat's widespread adoption.

Apache 2.0 has become the de facto standard for enterprise-grade open source projects. Leading projects like Spring Framework, Kubernetes, and TensorFlow all use this license, striking a good balance between protecting creators' rights and promoting ecosystem prosperity.

Benefits for Enterprise Users:

  • Business-friendly: Free to use in commercial closed-source projects without open source obligations
  • Patent grant: Clear patent usage rights, reducing intellectual property risks
  • Technology selection: Lower legal approval barriers, faster decision-making
  • Ecosystem participation: Free to customize and extend without contribution requirements

Strategic Significance:

  • Commercial application expansion: Enterprises can confidently apply Feat in fintech, e-commerce platforms, IoT, and enterprise internal systems
  • Ecosystem prosperity: Attract more contributors, promoting the development of third-party libraries, toolchains, and solutions
  • Long-term planning: Clear the path for future technology roadmap implementation

Upgrade Guide

Upgrading from v1.x

v2.0.0 is fully compatible with v1.x. Simply update the version number:

<feat.version>2.0.0</feat.version>

License Change Notice

After upgrading to v2.0.0, the project automatically applies the Apache 2.0 license. Enterprise users can confidently use it in commercial projects.

🚀 What's New

🤖 Feat AI: Enhanced Hook Mechanism for Observable AI Agents

We've significantly upgraded the Hook interface with three new streaming response methods, making AI Agent reasoning processes visible, observable, and interactive.

New Hook Methods

  1. onModelReasoning(String) - Capture the model's "inner monologue" (e.g., DeepSeek-R1's reasoning_content)
  2. onAgentReasoning(String) - Capture the ReAct agent's step-by-step thinking process
  3. onFinalAnswer(String) - Receive the final answer content

Why This Matters

When using reasoning models like DeepSeek-R1, users want to see AI's thought process without waiting for the complete response. v1.5.2 solves this by separating reasoning and final answers in real-time.

Quick Example

ReActAgent agent = new ReActAgent(opts -> {
    opts.hook(new Hook() {
        @Override
        public void onModelReasoning(String reasoning) {
            // Show deep thinking indicator
            System.out.println("💭 Deep reasoning: " + reasoning);
        }

        @Override
        public void onAgentReasoning(String reasoning) {
            // Show step-by-step analysis
            System.out.println("🤔 Analyzing: " + reasoning);
        }

        @Override
        public void onFinalAnswer(String answer) {
            // Display final result
            System.out.println("✅ Answer: " + answer);
        }
    });
});

🎨 New AI-Powered Website Design

The official website homepage has been completely redesigned with:

  • Dynamic gradient backgrounds with flowing light orbs
  • Terminal-style code showcase with live editor effects
  • F-E-A-T feature cards highlighting:
    • Free - Open source freedom
    • Elastic - Auto-scaling capabilities
    • Advanced - Cutting-edge technology
    • Tiny - Lightweight and fast
  • Fully responsive design from desktop to mobile
