• v7.8.4

  January 30, 2020

  v7.8.4 (2020-01-30)

  🍱 > ⚠️ 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.

  Thanks to @3cp, @BenoitZugmeyer, @pustovalov, @regiontog, and @vedantroy for their first PRs!
