🌲Rspack's tree shaking just got smarter 🦀 Two recent optimizations remove more unused code: 1. Inlined booleans can make branch-local dependencies inactive 2. Namespace default re-exports now preserve property-level usage More precise bundles, less dead code

Everyone is building AI agents. Very few are building the infrastructure needed to actually run and train them at scale. Today the veRL team at ByteDance open-sourced Uni-Agent: A unified framework for building, running, and training real-world agents. Why this matters: Most agent frameworks focus on orchestration. Uni-Agent focuses on infrastructure. It unifies: - agent execution - environment interaction - large-scale concurrency - RL training into one reusable stack. That means the same system can scale from: prototype → deployment → RL optimization without rebuilding the stack every time. The project is still early, but the direction is extremely promising for: - coding agents - browser agents - computer-use agents - large-scale agent training Open sourced by the team behind veRL (21k ⭐). Repo: github.com/verl-project/uni-… Would love feedback, contributors, and early adopters. #OpenSource #AI #AIAgents #RL #LLM #ByteDance

Two years building Midscene.js, we made a bet we should've made earlier: UI automation has to move from "reading the DOM" to "looking at the screen." So in our 1.0 release (Dec 2025), we dropped DOM compatibility entirely.
