Is this a live scrape of Unity release notes?

No. Scores and the heatmap are heuristics from version distance and a curated catalog. Verify every insight using the linked official Unity documentation and release pages.

Are package versions exact for my editor build?

The package table uses illustrative bundled versions for selected editor lines. Always compare your own Packages/manifest.json and lockfile before upgrading.

Can I share a comparison with my team?

Yes. Use Copy share link (query params from/to) or export Markdown and CSV from the tool.

Where are Unity 6 vs 2022 LTS upgrade guides?

The Official sources tab links What’s New pages, manuals, Scripting API roots, and Unity’s upgrade guide hub. Pair this tool with the Unity 6 Upgrade Wizard on this site for a step checklist.

Unity Version Deep Compare & Visual Explorer

Visual-first compare: scores, heatmap, ranked subsystems, package deltas (illustrative), and deep links to Unity’s manuals — with a stable shareable URL. Heuristic only; confirm against official sources.

How to use it

Choose Version A and B, then scan the summary and heatmap. Open the Official sources tab for What’s New, manuals, and Scripting API in both doc versions. For a ordered migration checklist, use the{" "} Unity 6 Upgrade Wizard.

## Upgrade checklist (template)
- [ ] Open both What’s New pages and skim Graphics + UI + your render pipeline.
- [ ] Diff `manifest.json` / lock and run tests on target platforms.
- [ ] Re-run CI player build; check IL2CPP / toolchain release notes if applicable.
- [ ] Search scripting API for types you subclass (obsolete / moved namespaces).
