Greptile Overview

Greptile Summary

This PR bumps the package version from 0.20.0 to 0.21.0, marking a new minor release. The change is a single-line update to the numba_cuda/VERSION file, which is the single source of truth for versioning in this project.

The version is dynamically read by the build system through numba_cuda/_version.py using importlib.resources, and referenced in both setup.py and pyproject.toml. This ensures consistent version information across the package.

According to the PR description, this release consolidates numerous features and improvements including:

Cache-hinted load/store operations
Enhanced third-party library testing
DWARF debug info improvements
Performance optimizations for kernel launches
Extensive refactoring and vendoring of Numba core modules
CI/CD improvements

Confidence Score: 5/5

This PR is safe to merge with minimal risk
Single-file version string update from 0.20.0 to 0.21.0 following semantic versioning. No logic changes, no potential for runtime errors. Version is properly read dynamically by build system with no hardcoded references elsewhere in codebase.
No files require special attention

@ashermancinelli Thanks for the review!

thanks for all your work Graham!

It's everybody else's (yourself included, of course)! I just review things and push buttons 🙂

Thanks! I'll start making updating Numbast's dependency with Numba-CUDA.

You might want to wait until the wheels publishing is fixed - I'm looking at this today.
