💥 BREAKING CHANGES 💥

• Minimum supported Node.js version is now 20.18.0

• Default exports are no longer available. See usage instructions for details on proper import syntax.

• ResultFormatter is no longer synchronous and can now return a Promise.

• Adoption of prettier@​3 requires some versions of Node to be executed with the --experimental-vm-modules option. E.g. NODE_OPTIONS="--no-warnings --experimental-vm-modules" npx jest.

• Attempting to install babel-plugin-tester alongside jest@<30 will cause NPM to fail with ERESOLVE. This is because only jest@>=30 (jest-snapshot) supports the prettier@​3 asynchronous interface.

• Allow testing entire babel transform result via outputRaw ([e9d5aa1][4]) ^{see [#​186][5]}
