The pages editor got some slight changes - for details see PAGES-112, ask fgrilli or talk with Andreas.

Pages to change:

• https://documentation.magnolia-cms.com/display/DOCS/Editing+pages ("Previewing pages")

There may be others pages. The person who tackles the ticket should please also do a search on DOCS with "page preview" and or "pages app".

As far as i understand, this is for 5.5 only.
