Google Search Console Products Enhancements Report Changes
In February 2021, Google did not support the data-vocabulary.org format anymore. Hence, now warnings regarding the usage of data vocabulary.org structured data emerge as an error in the rich results report.
Such amendments have shown an increase in errors in the reports and a gradual decrease in the warnings. However, there is no penalty for using data-vocabulary.org data, but one cannot use it to generate rich results.
In March 2021, the Search Console started checking the validity of FAQ and Q&A structured data, including below the root entity level.
Earlier Google used to check the entities at the root level. Still, the recently introduced changes have increased valid/warning/invalid FAQ and Q&A parts to display an accurate count of root and nested entities that Google can detect on your page.

Also, it is worth mentioning that the Search Console has brought about significant changes in what you need for the Education Experience and ExperienceInPlaceOfEducation properties of job posting markup. Hence, you can witness a drastic increase in warnings for job posting instances on your property.
In May 2021, Search Console has paved a new way that helps in evaluating and promulgating errors in Event structured data. Such changes have brought about minor increments in the number of event entities and issues reported for your property. Also, recorded changes have shown the severity of some problems, starting from errors to warnings. Just to let you know,
Search Console specifically detects event entities at all hierarchy levels, and it is not only about the root level. Therefore, the errors suspected in the concerned properties are flagged as warnings rather than errors.
