I'm not too familiar with the drama involved, but apparently some folks are changing uglify-es to either terser or babel-minify.

The claims on uglify-es state that it's unmaintained among a few other bad things, and that it contains some serious bugs, known to create tricky situations especially with React.

Parcel switching to terser
Ledger switching away from uglify
Twitter thread about this

Like I said, I don't have any in-depth knowledge about the situation and this is just a heads-up about something I noticed by chance.

Thanks to @arrgh for suggesting this replacement: #10042

This may help with lots of issues, most recently #10044 but also #10034,
fall back to `Babel.minify` when `uglify-es` (now `terser`) fails, there
should be fewer problems with `Babel.minify` (parse errors, performance,
memory usage) if `terser` succeeds more often.

Done! To try out the new minifier, run meteor update --release 1.7.1-beta.14 or create a new app with meteor create --release 1.7.1-beta.14 your-new-app.
