 ## 🎉 News
-* **May 07, 2024, we introduced "Iterative Experience Refinement" (IER), a novel method where instructor and assistant agents enhance shortcut-oriented experiences to efficiently adapt to new tasks. This approach encompasses experience acquisition, utilization, propagation, and elimination across a series of tasks. Our preprint paper is available at https://arxiv.org/abs/2405.04219, and this technique will soon be incorporated into ChatDev.**
+* **June 12, 2024, We introduce Multi-Agent Collaboration Networks (MacNet) 🎉, which utilize directed acyclic graphs to facilitate effective task-oriented collaboration among agents through linguistic interactions 🤖🤖. MacNet supports cooperation across various topologies and among more than a thousand agents without exceeding context limits. More versatile and scalable, MacNet can be considered a more advanced version of ChatDev's chain-shaped topology. Our preprint paper is available at [https://arxiv.org/abs/2406.07155](https://arxiv.org/abs/2406.07155). This technique will soon be incorporated into this repository, enhancing support for diverse organizational structures and offering richer solutions beyond software development (e.g., logical reasoning, data analysis, story generation, and more).**

 * December 28, 2023: We present Experiential Co-Learning, an innovative approach where instructor and assistant agents accumulate shortcut-oriented experiences to effectively solve new tasks, reducing repetitive errors and enhancing efficiency.  Check out our preprint paper at https://arxiv.org/abs/2312.17025 and this technique will soon be integrated into ChatDev.
