CHANGELOG.md

4.3.2

• Fixed usage with externalHelpers: true option

4.3.1

• Add .js extension to the virtual babel helpers file (only matters when using preserveModules option in rollup)

4.3.0

• Added .custom builder.
• Fail build when a plugin tries to add non existent babel helper

4.2.0

Allow rollup@1 as peer dependency.

4.1.0

• Fixed "preflight check" for ignored files.
• Return null when no transformation has been done (fixing source maps for this case)

4.0.3

Fixed fallback class transform in "preflight check".

4.0.2

Fixed rollup peer dependency.

4.0.0

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.

3.0.3

• Drop babel7 support. Use 4.0.0-beta if you use babel 7
• Use "module" in addition to "jsnext:main" (#150)
• Remove unused babel helpers namespace declaration & expression (#164)

3.0.2

• Fix regression with Babel 6 (#158)

3.0.1

• Wasn't working, fix bug with transform (not using es2015-classes for preflight check)

3.0.0

• Drop Node 0.10/0.12 (Use native Object.assign)
• Change babel-core to be a peerDependency
• Support babel-core v7 as well as a peerDep (no changes necessary)
