+## 📰 News
+
+- **[2026.09.07]** 🎉 The model checkpoints are now open-sourced on [Hugging Face](https://hf.co/collections/Jackwang111/m2rl) and [ModelScope](https://modelscope.cn/collections/whq1111/M2RL)! **Feel free to use our checkpoints for your post-training research (e.g., weight merging, multi-teacher on-policy distillation)!**
+- **[2026.07.09]** 🎉 Our paper is accepted to **COLM 2026**!
