Group the ThreadSanitizer and HardwareAssistedAddressSanitizer changes under a single top-level bullet point. This makes it easier to add a third sanitiser-related change.
No (intended) change to the actual text or wording. (TBH I don't understand the ThreadSanitizer bit: is it describing three changes (KCSAN + two new options), four changes (other environments), or one big inter-related change?) OK to install?
