## Next Steps (Optional Enhancements)

### 1. Development Status Update
The `pyproject.toml` still shows `Development Status :: 4 - Beta`. Consider updating to:
```toml
"Development Status :: 5 - Production/Stable"
```
This requires a new release (2.4.1) to update PyPI metadata.

### 2. PyPI Description Enhancement
The current description is good, but could be enhanced with:
- More prominent Quick Start code block
- Feature comparison table
- Performance metrics (P99 latency, cache hit rates)

### 3. GitHub Release Notes
Create a GitHub Release for `v2.4.0` with:
- Summary of changes from 2.3.4
- Migration guide (if needed)
- Links to documentation

### 4. Documentation Updates
- Update any references to "Release Candidate" or "Beta" status
- Add production deployment guide
- Create migration guide from previous versions
