    🆕 New Features

    Filter objects by count of references (#1101)
    🚀 Weaviate has already offered substantial "filter by references" capabilities in the past, such as "Find all Cities located in a Country with a population size larger than x". However, prior to this release it was not possible to filter for cases such as "Show all Cities not associated with a Country" or "Find all authors who wrote at least 2 articles".

    🚀 This release adds the ability to filter by reference count. To do so, simply provide one of the existing compare operators (Equal, LessThan, LessThanEqual, GreaterThan, GreaterThanEqual) and use it directly on the reference element. For example, the following GraphQL query:

    { Get { Things { Author( where:{ valueInt: 2operator:GreaterThanEqualpath: ["WroteArticles"] } ) { nameWroteArticles { ... on Article { title } } } } } }

    📚 Note: The example above uses the News Publication dataset.
