     *   <li>
     *     Update the {@code TaskQuery} interface;
     *   </li>
     *   <li>
     *     Implement the new property filter and getters/setters in {@code TaskQueryImpl};
     *   </li>
     *   <li>
     *     Add the new property filter in the engine-rest {@code TaskQueryDto} class;
     *   </li>
     *   <li>
     *     Use the new filter in the engine-rest {@code TaskQueryDto#applyFilters} method.
     *     The method is used to provide Task filtering through the Rest API endpoint;
     *   </li>
     *   <li>
     *     Initialize the new property filter in the engine-rest
     *     {@code TaskQueryDto#fromQuery} method; The method is used to create a {@code TaskQueryDto}
     *     from a serialized ("saved") Task query. This is used in Tasklist filters;
     *   </li>
     *   <li>
     *     Add the property to the {@code JsonTaskQueryConverter} class, and make sure
     *     it is included in the {@code JsonTaskQueryConverter#toJsonObject} and
     *     {@code JsonTaskQueryConverter#toObject} methods. This is used to serialize/deserialize
     *     Task queries for Tasklist filter usage.
     *   </li>
     *   <li>
     *     Tests need to be added in: {@code TaskQueryTest} for Java API coverage,
     *     {@code TaskRestServiceQueryTest} for Rest API coverage and
     *     {@code FilterTaskQueryTest} for Tasklist filter coverage.
