  ## Breaking changes
  -The list of breaking changes is long (and can be seen fully in the [changelog](https://github.com/facebook/jest/blob/main/CHANGELOG.md#2800)), but for migration purposes, we've also written [a guide](/docs/upgrading-to-jest28) you can follow. Hopefully this makes the upgrade experience as frictionless as possible!

  Main breaking changes likely to impact your migration are dropped support for Node 10 and 15 (but _not_ Node 12, which will be EOL in a few days) and some renamed configuration options.
