What
Thumbnails: when Claude Code uploads a file as an attachment, the upload can now include an optional thumbnail JPEG (a small preview picture, sent as thumbnail.jpg) next to the file itself. Upload attachments pass a checked thumbnail field along. Before, only the file was sent.
Stopped-task reminder: the note Claude receives when a task stops now reads Task "..." (...) was stopped.. It used to say was stopped by the user..
Why
Uploaded files can come with a preview image. Claude is no longer told that you stopped a task when something else may have stopped it.
