Items placed on an InDesign master page now arrive with the document. A master holds what a document repeats — a logo, a footer rule, a running header, a background panel — and none of it came through: a page that looked complete in InDesign arrived holding only the items drawn directly on it. Each spread now receives what its master puts on it, behind the spread's own items, and a spread whose two pages use different masters receives both.
Master items arrive locked and grouped under the name of the master they came from, so they read as the repeating furniture they are rather than as loose items on the page. That matches InDesign, where a master item cannot be edited on the page until it is deliberately released.
A stroke weight can be set for new text, beside the stroke colour that was already there. Preferences ▸ Text offered a colour for the outline of the letters and no way to say how thick it should be, so every new text frame started at none however the preference was set. It now offers both, and starts at 0 pt — no outline — as it always did.
