Webstorm said there's an update. The dialog has 3 buttons: "Release notes", "Remind me later", and "Ignore this update." None of these says to me, "This will update your installation." So I try "Release notes" since it's the only one that doesn't say "I won't update your installation." Then it takes me to a webpage saying I can download a trial version.
This is confusing. I've seen another question about consecutive updates and automatic updates, but it looks like my version is only one version out of date. It says it will go from 4.0.2 to 4.0.3.
