Google on Sunday, January 31, 2021, will stop supporting markup in the format from data-vocabulary.org. Google gave us over a years notice of this change, so this change should not come as a surprise to anyone here.
In fact, Google initially said they would remove this support on April 6, 2020, but then pushed off that deadline January 31, 2021. And that date is here, it is coming this upcoming Sunday.
So if you are one of those who wait to the last minute to make these changes - the last minute is here.
Google's John Mueller even tweeted a reminder earlier this week:
In case you missed it & are still using https://t.co/WMqBbrVCV2 markup. https://t.co/5l3HrIVIsH

Update: Google posted as of February 2, 2021, data-vocabulary.org format is no longer supported by Google for rich results.
The data-vocabulary.org format is no longer supported by Google for rich results. All warnings about usage of data-vocabulary.org structured data will now appear as errors in your rich results reports. Therefore you might see a decrease in warnings and increase in errors in your reports. There is no penalty for using data-vocabulary.org data, but it will not be used to generate rich results.
If you're using https://t.co/N98EXBIRJ6 structured data, keep in mind that we no longer support that format for rich results: https://t.co/M2CK6p98Ye

There's no penalty for using unsupported structured data, it just won't be used in Search for rich results. You can check the structured data on a page using the Rich Results Test: https://t.co/6O8U7kKmV0
