Dependency freshness
| Package | Declared | Latest | Status |
|---|---|---|---|
| FastAPI fastapi | 0.115.5 | 0.146.0 | Behind, not counted |
| NumPy numpy | 1.24.0 | 2.5.4 | 1 major behind |
Declared = lowest version the kit's dependency file (package.json, pyproject.toml or requirements.txt) allows. Latest = the npm "latest" tag or the newest PyPI release. TypeScript, the Stripe SDK, FastAPI and other 0.x packages are shown but not counted in the verdict.
