Hi @gustawdaniel,

I don't think that updating webpack-dev-server is required, our current range (^3.1.14) already allows people to use 3.7.2.

As for url-loader@^2 there are some things to consider:

• it should already be possible to use url-loader@^2 with Encore since that's a dev-dependency (maybe with a warning but it won't prevent it from working fine)
• the version is quite recent so it may be a good idea to wait for a bit before updating (for instance 2.0.0 introduced the following regression which was fixed 3 days ago: Specifying options as a query string does not work anymore webpack-contrib/url-loader#183)
• this is a major bump which introduces breaking changes: one of them being the min Node.js version set to >=8.9.0. It means that people using >= 8.0.0 <8.9.0 won't be able to use the url-loader without a warning since our version requirement is 8.* || >= 10.*). One solution to that would be to allow both url-loader@^1 and url-loader@^2 (Encore doesn't set any option so it should not break anything).

Ok. So I closing this pull request. Thanks for explaination @Lyrkan

As I said I'm not entirely against this, having something like "url-loader": "1.* || 2.*" would be a valid way of doing it without requiring people with to update Node.js or the url-loader.
