Does a master component edit in a linked Creative Cloud library propagate to all .xd files using its instances?

I maintain several Adobe XD documents that share components through a linked Creative Cloud library. Before committing to a large design-system cleanup, I need to pin down the documented propagation behavior of master components in this setup, since XD is now in maintenance mode and I want to avoid relying on assumptions from older guides.

My specific goal is to understand what happens when I edit a master component in the source document that publishes the library: which instances in consuming .xd files update automatically, which require manual acceptance, and what happens to instances that have local overrides such as changed text or resized elements. I am also unsure how this interacts with documents that were last saved before the library link was established.

Assume a current XD desktop build on Creative Cloud in 2026; I can verify behavior in-app, but I want the expected semantics first.

1. Do master component edits propagate to instances in other .xd files automatically on next open, or only after an explicit library update action?
2. Are overridden properties on instances preserved when the master changes, and which override types block propagation?
3. Given maintenance mode, is this library propagation behavior still officially documented and supported?
