v4.0.1

Compare Source

v4.0.0

Compare Source

Babel 7 compatible! (dropped Babel 6 compatibility though).

Additionally:

• Internal preflight checks are created now per plugin instance, so using 2 instances of rollup-plugin-babel (i.e. targeting 2 different set of files with include/exclude options) shouldn't conflict with each other
• Transpiling by default only what Babel transpiles - files with those extensions: .js, .jsx, .es6, .es, .mjs. You can customize this with new extensions option. This also fixes long standing issue with rollup-plugin-babel trying to transform JSON files.
