Current Version	3.13.1

The version 4.1.0 is not covered by your current version range.

Without accepting this pull request your project will work just like it did before. There might be a bunch of new features, fixes and perf improvements that the maintainers worked on for you though.

I recommend you look into these changes and try to get onto the latest version of node-sass. Given that you have a decent test suite, a passing build is a strong indicator that you can take advantage of these changes by merging the proposed change into your project. Otherwise this branch is a great starting point for you to work on the update.

Release Notes

v4.1.0

Alpine Linux support

The Linux binaries we supply are not compatible with the way Node is compiled on Alpine Linux. This means that although the installation will succeed, it takes much longer because the native code needs to be compiled locally.

Thanks to the hard work of @lox and @S-YOU we're now able to supply Alpine Linux compatible binaries.

Read more about what was involved in #1589.

Fixes

Replace lodash.isarray with Array.isArray (@daltones, #1829)
CLI prematurely exiting before the output stream is fully flushed (@ysugimoto, #1823)
