The new WebStorm 2018.1 Early Preview build (181.4096.12) is now available!
Update: we've released a new build #181.4096.25 to fix a performance issue introduced in build #181.4096.12, published on March 7th, 2018. The IDE was consuming lots of CPU resources after running npm install or adding many new directories to the project.
You can update via Toolbox App, or download the build here and
