Release notes - Improve the Security of Your Page <Head> Markup

Hey all,

This is probably a stupid question, but just wanted confirmation - There is an upcoming change in Summer '17 relating to LockerService and I just wanted to confirm that it will only impact Lightning Components and not Visualforce pages. Whilst the item is within the LockerService section of the notes, the text doesn't explicitly call out the technology it will impact.

With thanks,
Andy
