One of the greatest strengths of open source software is that it is open and free for anyone to contribute. This also leads to one of its greatest challenges, which is to support consistent, sustainable maintenance.

Babel isn't a company. As mentioned in the 7.0.0 post, the all-volunteer Babel team (sans Henry) has been doing its best to steward the project and handle all the expectations of the community. We're glad that we have continued to make releases, but even keeping up-to-date with reported issues is difficult to manage, let alone our integrations with other tools, new proposals, and effect on the greater ecosystem.

In March 2018, Henry left his job to start working on securing more funding for Babel. After a lot of work and support from the community, the team was able to fund Henry as a full-time maintainer.

This has been a big win for the team, but we're finding that it is not enough.

Today we are releasing Babel 7.7.0!

This release includes new parser features like top-level await (await x(), Stage 3) and Flow enum declarations (Flow proposal). And now, @babel/parser has the option of recovering from certain syntax errors!

We've also added support for TypeScript 3.7: Babel can parse and transform private class fields with type annotations, public class fields annotations defined using the declare keyword, type assertion function signatures and template literals in enum declarations.

Babel now understands three new configuration files: babel.config.json, babel.config.cjs and .babelrc.cjs, which behave the same as babel.config.js and .babelrc.js files.

Lastly, Babel 7.7.0 uses 20% less memory than 7.6.0.
