If you only use guided tours on WMF wikis, you don't have to read the
rest of this.
Third-party users of GuidedTour should upgrade to latest master to
resolve a security issue, bug 49175
(
https://bugzilla.wikimedia.org/49175). Without the fix, tour
JavaScript may execute in inappropriate places, such as the login screen.
This has already been deployed to all WMF wikis.
