Your typing now reaches disk while you are still typing. Tine waited for a pause,
and every keystroke restarted the wait, so a long passage wrote nothing.

Edits are saved when the app is backgrounded, not only on a clean close.

Editing one block no longer rewrites blocks you never touched.

Undo can no longer overwrite a file that changed while the page was out of memory.

A page changed by another app or sync client no longer becomes unsaveable.
