October 27, 2022

We just published Babel 7.20.0!

This release includes support for TypeScript 4.9, and parser support for the Import Reflection and Explicit Resource Management Stage 2 proposals. Additionally, you can now use Deno as one of your compilation targets.

In the past few releases we have made gradual improvements @babel/generator's code location tracking, which lead to higher source map quality and better positioning of comments in the generated output.

We are also releasing version 9.0.0 of babel-loader, the Babel loader for Webpack.

7.15.0 Released: Hack-style pipelines, TypeScript const enums and Rhino target support

July 26, 2021

Babel Team

This release enables parsing top-level await (Stage 4 at the May meeting) and transforming ergonomic brand checks for private fields (Stage 4 at the July meeting) by default. There is also now support for the Hack-style pipeline operator. We also improved our TypeScript support, implementing transform support for const enums and namespace aliases, and we expanded our heuristics to add .displayName to React components created by React.createContext() (#13501).

We also introduced a new compiler assumption, noIncompleteNsImportDetection, to produce a smaller output when compiling ECMAScript modules to CommonJS without worrying about partially initialized namespace imports caused by module cycles.

Additionally, you can now specify Rhino as a compilation target.

Babel is used by millions, so why are we running out of money?

May 10, 2021

Babel Core Team

Since 2018, Babel has been doing a funding experiment: can full time work on Babel be sustained? We've learned the answer might be no.

7.14.0 Released: New class features enabled by default, TypeScript 4.3, and better CommonJS interop

April 29, 2021

Babel Team

Babel 7.14.0 is out!

This release enables class fields and private methods by default (they were promoted to Stage 4 during the recent April TC39 meeting!) and adds brand checks for private fields and static class blocks to @babel/preset-env's shippedProposals option.

We added support for Stage 1 async do expressions (using @babel/plugin-proposal-async-do-expressions), which extends the Stage 1 do expression proposal.

Thanks to Sosuke Suzuki and Pig Fang, Babel can now handle TypeScript 4.3 features. @babel/parser also has a new option to correctly parse TypeScript declaration files.

Finally, we introduced a new importInterop: node option to make it easier to produce dual modules by compiling ECMAScript imports to CommonJS that follow Node.js semantics.

7.13.0 Released: Records and Tuples, granular compiler assumptions, and top-level targets

February 22, 2021

Nicolò Ribaudo

We just published Babel 7.13.0, the first minor release of 2021!

This release includes some important features to @babel/core: a targets option (similar to @babel/preset-env's one) that can be shared across different plugins, an assumptions option to precisely tune your configuration to produce a smaller compilation output, and support for plugins and presets written using native ECMAScript modules.

Babel now supports transforming the Records and Tuples ECMAScript proposal, which brings immutable data structures and structural equality to JavaScript, and parsing the Module Blocks proposal.

Additionally, we added support for some new Flow and TypeScript features.

7.12.0 Released: TypeScript 4.1, strings as import/export names, and class static blocks

October 15, 2020

Nicolò Ribaudo

We just published a new minor version of Babel!

This release includes support for the new TypeScript 4.1 beta features: template literal types and key remapping in mapped types.

Additionally, we implemented two new ECMAScript proposals: class static blocks and imports and exports with string names.

Lastly, we renamed @babel/plugin-syntax-module-attributes (and the corresponding parser plugin moduleAttributes) to @babel/plugin-syntax-import-assertions (and importAssertions), to match the recent proposal updates. The old plugin will work until Babel 8, but it's deprecated now.
