 - **[🎉Hybrid Cache Acceleration](./docs/User_Guide.md#taylorseer-calibrator)**: Now supports hybrid **Block-wise Cache + Calibrator** schemes (e.g., DBCache or DBPrune + TaylorSeerCalibrator). DBCache or DBPrune acts as the **Indicator** to decide *when* to cache, while the Calibrator decides *how* to cache. More mainstream cache acceleration algorithms (e.g., FoCa) will be supported in the future, along with additional benchmarks—stay tuned for updates!  
 - **[🤗Diffusers Ecosystem Integration](https://huggingface.co/docs/diffusers/main/en/optimization/cache_dit)**: 🔥**cache-dit** has joined the Diffusers community ecosystem as the **first** DiT-specific cache acceleration framework!
