Release Notes

babel/babel

v7.8.4

Compare Source

⚠️ In Babel 7.8.0 we introduced the --copy-ignored option for @babel/cli, defaulting to false. However, previous versions behaved as if that option was present: for this reason, we changed its default value to true (when --copy-files is provided) and introduced a --no-copy-ignored option to disable it.
