Research updates

What changed, and why.

This page collects the update-log entries from every guide, review and comparison, newest first. Each entry has a date and a label: Checked for a routine re-check that changed nothing, Updated for new or revised content, Corrected for a fixed error, and Status re-checked for a fresh look at regulatory status. An updated date means something was actually re-checked, and every entry says what it was.
