## Changes to existing queries

|--------------------------------|------------------------------|---------------------------------------------------------------------------|
| Incomplete URL substring sanitization (`js/incomplete-url-substring-sanitization`) | More results | This query now recognizes additional URLs when the substring check is an inclusion check. |
| Ambiguous HTML id attribute (`js/duplicate-html-id`) | Results no longer shown | Precision tag reduced to "low". The query is no longer run by default. |
