More relevant answers, and help getting the widget installed.

Improved: Answers draw on up to four times more source text per answer (the retrieval cap rose from 500 to 2,000 characters), so long articles are quoted more completely.
Improved: New bots use a newer embedding model for more accurate matching, and existing bots can be upgraded from their settings.
New: After you install the widget, the Deploy page detects it on your site and shows a confirmation. If it is not detected, a reminder email follows with the install steps.
Fixed: The widget showed the wrong bot name in some cases.
