### Upgrade notice

- torch-npu is upgraded to 2.7.1.post1. Please note that the package is pushed to [pypi mirror](https://mirrors.huaweicloud.com/ascend/repos/pypi/torch-npu/). So it's hard to add it to auto dependence. Please install it by yourself.
- CANN is upgraded to 8.3.rc2.

### Known Issues

- Qwen3-Next doesn't support expert parallel and MTP features in this release. And it'll be oom if the input is too long. We'll improve it in the next release

- Qwen2-audio doesn't work by default. Temporary solution is to set `--gpu-memory-utilization` to a suitable value, such as 0.8.
- CPU bind feature doesn't work if more than one vLLM instance is running on the same node.
