- Find the latest version of Mediabunny with `npm view mediabunny version`.
- In the root `package.json`, update the `catalog` versions for `mediabunny`, `@mediabunny/mp3-encoder`, and `@mediabunny/ac3` to that version.
- In `packages/template-*/package.json`, update `mediabunny` and any `@mediabunny/*` packages to the same version. Templates use explicit versions, not `catalog:`, so update them manually.
- Update `packages/cli/src/extra-packages.ts` with the new Mediabunny version.
- Update `packages/studio-shared/src/package-info.ts` with the new Mediabunny version in `extraPackages`.
- Update the compatibility table in `packages/docs/docs/mediabunny/version.mdx`. To find the next version this upgrade will be applied to, look in the root `package.json` for the version and increment the patch version by 1.
- Run `bun i` at the end.
