With WebStorm 9 release right around the corner (you can download WebStorm 9 beta right away), we are publishing the WebStorm 8.0.5 maintenance update to support debugging in the latest Chrome 38.
Patch update is available only for Windows and Linux users. We ask our Mac users to install WebStorm 8.0.5 from our website or use WebStorm 9 beta. The reason is that we applied some changes to the app preparing for the Yosemite release.
Develop with pleasure!
