Methodology & Quadrant Definitions

Our release radar synthesizes public release notes, package versions, and tag histories from official upstream publishers:

Monthly Cadence: Calculated from the frequency of tracked releases over the active lifetime of each repository in our archive.
Stability Index: 100% − (Breaking Releases ÷ Total Releases). A high score means the maintainers prioritize backwards compatibility and stable semantic versioning.
Average Impact Score: Evaluated using our multi-model AI analyzer assessing structural, architectural, and DX impact (scaled 1 to 10).

Note: Release frequency alone does not reflect software quality or production fitness. Small libraries may legitimately have low cadence if they are feature-complete. Review full source notes before planning major upgrades.
