@andreicristianpetcu it is breaking change and break plugin on node@6 (eaking change: Drop support for Node < 8. If you want to support older versions of node, please use v0.6 or below.). We can't do this right now

@evilebottnawi Any chance we can get this released behind an opt-in flag.
My teamis having some production issues related to #272 e.g. out of memory and long build times. As I think we have determined, it's most likely due to a combination of unoptimized code in uglifyJS but also the cost of making source-maps. While there is nothing we can really do about the uglify js code, at least improving the source-map generation might help with that issue.

@mlavina it is not easy, because it is require
nodejs@8version minimum, but if you have ideas how we can fix it, PR welcomemlavina commentedon Aug 27, 2018
@evilebottnawi I will try to get a solution as soon as I can, but that might be a while to be honest.
However, a quick source-map gain that we might gain is if we can get this PR webpack/webpack-sources#23 merged for webpack-sources
Especially since in #272 we saw that
source-mapswere part of the problem.
