 ## ChangeLog for RottenLinks
 
+### 2.0.1 (16-12-2023)
+* Add `requireExtension` to updateExternalLinks.
+* Remove unnecessary object cache from being added in updateExternalLinks.
+* Prevent duplicate entries from being added to rottenlinks table in updateExternalLinks.
+* Fix table name used in RottenLinksJob.
+
 ### 2.0.0 (15-12-2023)
 * Redesign RottenLinks to not depend on a maintenance script
 * Changes how we count page usage on RottenLinks special page. We directly gather this from externallinks table rather then storing it separately.
