Is there a Hot Patch available for TE-16814 - Fixed date formatting in QAPage structured data?

Rookie mistake: We updated to 12.0.1.15778 without checking that there was an update last week. I see that there was a fix for the date formatting in structured-question-data.vm issue that Google Search console is complaining about unparsable structured data. (TE-16814 - Fixed date formatting in QAPage structured data)

Is that available as a Hot Patch or do we need to do another full upgrade to 12.0.1.16198?
