It looks like Google added a whole set of new manual actions to the list of manual actions. The new ones are for Google News and Google Discover guideline violations.
A Google manual action is when a human at Google issues a sort of penalty (Google does not like to call it a penalty) against a site when a human reviewer at Google has determined that pages on the site are not compliant with Google's webmaster quality guidelines. Google said that most manual actions address attempts to manipulate Google's search index. Most issues reported here will result in pages or sites being ranked lower or omitted from search results without any visual indication to the user.
Google added some details about this in the Google News content policies help document and Google Discover content policies help document. @PublisherCenter, not an official Google account, notified me of this addition. They read as follows:
News manual actions in Search Console
News manual actions can appear in your Search Console account under Security & Manual actions when your site violates one or several Google News content policies.
Discover manual actions in Search Console
When your site violates one or several Discover content policies, Discover manual actions can appear in your Search Console under Security & Manual actions. Learn more about the types of violations and how to fix them.
Here is a link to the specific Google News and Discover manual actions. Here is what they are:
