Superseded by #1244 — and held there rather than landed.

@babel/preset-env@8.0.5 declares peer @babel/core@"^8.0.0", but @react-native/babel-preset@0.82.0 depends on @babel/core@^7.25.2. Taking Babel 8 for any one of these packages puts two major Babel cores in a single tree and breaks the Metro transform — they move together, with react-native, or not at all.

#1244 records this as an ignore entry for Babel majors so it stops being re-proposed. Minor/patch and security updates on the 7.x line still flow. Worth revisiting when react-native moves off its 0.82.0 pin.

dependabot · 2026-09-16T21:19:45Z

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
