 ### Fixed
 
+- Publish Dataset modal custom messages now render configured HTML links and line breaks.
 - Edit Dataset Terms: navigate to the draft version of the dataset after saving changes to the terms, instead of the latest published version.
 - After saving on either Edit Template tab (Metadata or Terms), the user is redirected to the templates listing with a success toast instead of staying on the edit page.
 - Edit Template breadcrumb on the Terms page no longer renders the dataset's "Terms and Guestbook" label (templates have no guestbook).
