When you ask to change just one detail, such as a character's age, the assistant can now update that entry directly. It can distinguish the target entry even when another character has the same text.
When you ask to save a reply exactly as written, the assistant can copy the original conversation text directly into a reference document, preserving spaces and line breaks.
The assistant can also inspect manuscript headings and the order of text blocks without loading the manuscript's prose.
These improvements help the assistant read and change the requested portion of a work. Changing the structure of a reference document remains a separate operation.
