Hey @yigalirani! We really appreciate you taking the time to report an issue. The collaborators on this project attempt to help as many people as possible, but we're a limited number of volunteers, so it's possible this won't be addressed swiftly.

We're also running into an error when using 7.10.0 with @babel/standalone while using the stage-0 preset:

Error: [BABEL] unknown: The 'moduleAttributes' plugin requires a 'version' option, representing the last proposal update. Currently, the only supported value is 'apr-2020'. (While processing: "base$1$0$0")
    at babel.min.js:1

    at Generator.forEach.e.<computed> [as next] (babel.min.js:1)

It seems like the stage-1 preset defaults the version to may-2020 and that option doesn't seem to be overridable from the stage-0 preset: https://github.com/babel/babel/blob/master/packages/babel-standalone/src/preset-stage-1.js#L13

Should all options for stage-0 be spread down so users can also configure stage-1, stage-2, etc?

I just noticed the linked pull request won't resolve the error we're running into above, would it be better to open up a new issue to track this?

[nicolo-ribaudo]

@hamlim Could you open a PR adding that option to the stage 0 preset? We can merge it for the next patch.

[hamlim]

Sure!

@nicolo-ribaudo I tried using make build-dist to build locally and test but it doesn't seem to create the single file entry for the standalone package, do you know how I can test this locally?

Edit: Found a way to test locally, and opened the following PR: #11631

I think this issue should still be open as there is another issue with the 7.10 release of babel-standalone unrelated to the PR that was merged above cc @existentialism
