If you are moving from an older version (like 1.9) to this "complete" 3.1.4 release, you gain access to the major Scrivener 3 overhaul :
: Replaces the old Project Notes, allowing you to view up to four documents (notes, research, or other chapters) simultaneously in the main window.
: A more flexible system for exporting your manuscript to formats like ePub 3 , Kindle, and PDF.
: A true style system for consistent formatting (headings, block quotes) that integrates directly with the compiler.
: A tool that lets you highlight specific parts of speech (e.g., only dialogue, adverbs, or verbs) to help with self-editing.
: A flatter, more refined UI with a dedicated Dark Mode .
