Code Review

This pull request bumps the project version to 0.2.7. The change itself is correct. However, a corresponding update to CHANGELOG.md is missing. I've added a review comment to suggest adding a changelog entry for this new version, which is an important practice for keeping users and contributors informed of the changes.

A version bump should be accompanied by a changelog update. Please add an entry for v0.2.7 to CHANGELOG.md detailing the changes since the last release. This is crucial for maintainability and for keeping users informed about what's new in this version.

After upgrade flashinfer to v2.7.0, I got the error when run test_trtllm_allreduce_fusion.py :

ModuleNotFoundError: No module named 'flashinfer.comm'

With commit 27060628c32e1217e27564adf24e33273f4c8287 , it's ok.
