After almost 2 years, 4k commits, over 50 pre-releases, and a lot of help we are excited to announce the release of Babel 7. It's been almost 3 years since the release of Babel 6! There's a lot of moving parts so please bear with us in the first weeks of release. Babel 7 is a huge release: we've made it faster, created an upgrade tool, JS configs, config "overrides", more options for size/minification, JSX Fragments, TypeScript, new proposals, and more!

Moving forward with v7, we've decided it's best to stop publishing the Stage presets in Babel (e.g. @babel/preset-stage-0).

We didn't make this decision lightly and wanted to show the context behind the interplay between TC39, Babel, and the community.

For those of us that need to support older browsers, we run a compiler like Babel over application code. But that's not all of the code that we ship to browsers; there's also the code in our node_modules.

Can we make compiling our dependencies not just possible, but normal?

Happy Birthday Babel! 🎂 (Sept 28)

Babel has really come a long way since Sebastian started the project only 3 years ago! A while back it was renamed from 6to5 to Babel; for good reason as it has significantly contributed to the use of ES2015+ by many companies, libraries, and developers alike.

If you didn't know already, we're planning on releasing a 7.0 version soon 🙌 ! Work on it actually started back in February, when I just wanted to make a release to drop Node 0.10/0.12 support and remove babel-runtime and various other code. And since then, we've done releases up to alpha.20.

Babel started out as a transpiler to let you write the latest version of the ECMAScript specification but ship to environments that don't implement those features yet. But it has become much more than that. "Compilers are the New Frameworks" says Tom Dale and I could not agree more. We're seeing more and more compile-time optimizations for libraries and frameworks. I'm not talking about syntax extensions to the language, but simple code transformations that enable patterns that would be difficult to accomplish otherwise.

Getting to work your way around a new code base always poses its challenges, and Babel was no exception.

I’ve been working with Babel as part of the Google Summer of Code 2017 program, working to update Babel transforms and the Babylon parser to accommodate changes to specifications and implementing new features.

Here’s a few things I’ve learnt from my adventures so far.
