I've tried it on Webstorm 8 EAP and PyCharm and I got
Plugin 'com.codeivate.plugin' failed to initialize and will be disabled. Please restart WebStorm.
com.intellij.diagnostic.PluginException: com/codeivate/plugin/CodeivateApplicationPlugin : Unsupported major.minor version 51.0 [Plugin: com.codeivate.plugin]

Hey, no problem! Congrats!
