The proofreader got a tune-up. Suggestions now land in exactly the right place (no more highlights drifting mid-sentence), adding a word to your dictionary immediately re-checks the page, and old suggestions clean themselves up properly after edits. Fewer false alarms, tidier margins.
No more surprise formatting while you type. A few of you noticed that typing certain characters (like backticks or a # at the start of a line) could suddenly change your font or turn a line into a heading — that's fixed, so your formatting stays exactly as you typed it.
Sharing looks better. Shared chapter links now show the chapter's actual title in previews (in messages, social posts and the like), and outdated links now land on a friendly explanation page instead of an error.
A round of behind-the-scenes improvements to keep everything fast and dependable.
