· One min read

Version 4.2.0 is out!

Here's what's new:​

  • When the source map URL is inline, don't write it to a file.
  • Fixed output parens when a lambda literal is the tag on a tagged template string.
  • The mangle.properties.undeclared option was added. This enables the property mangler to mangle properties of variables which can be found in the name cache, but whose properties are not known to this Terser run.
  • The v8 bug where the toString and source representations of regexes like RegExp("\\\n") includes an actual newline is now fixed.
  • Now we're guaranteed to not have duplicate comments in the output
  • Domprops updates
