Episode notes
Use PyPI+ For Deeper Package Discovery
- PyPI+ provides richer package discovery with dependency graphs and health scores to evaluate libraries.
- Use it to inspect dependents, versions, and maintenance metrics before adopting a package.
Automate Safe Releases With uv-ship
- Use uv-ship to verify repo state, bump versions, and publish releases while reviewing each step.
- Run the dry-run first and install it as a uv tool for a consistent, repeatable release workflow.
3.14 Narrows Free-Threaded Penalty
- Python 3.14 improves multithreaded performance while reducing the single-thread free-thread overhead seen in 3.13.
- Upgrade when you need better threaded scalability, but check dependency compatibility for free-threaded builds.
