on the PHPStorm site a see a new version 7.1. My installation runs with 7.0 and the updates function didnt notice the new version. The "check for updates in channel" is set an the selectbox is in "New Major Version Releases".
Is the next Major Version 8.0 and not 7.1?
Is 7.1 the "next milestone release" ?
Anyway, to switch the selectbox dont change anything now.
