Added optional dryRun parameter to the body of the create and update relationship operations

Preview the results of the operation by setting the dryRunbody parameter to true.

Added several objects in the response body for the get relationship types and list relationship types operations

The new reponse objects include:

• singleTarget: When true, a record can be the from record in at most one relationship of this type (for example, a single parent). When unset, a record can have any number of relationships of this type.
• acyclic: When true, relationships of this type cannot form a loop; following the chain of relationships from any record never leads back to that same record. When unset, loops are allowed.
• maxDepth: The maximum number of levels of relationships of this type allowed above a record when a new relationship is created from it, from 1 to 100, which limits how deep the hierarchy can grow. When unset, there is no depth limit.

Added optional fromRecordVersion and toRecordVersion objects to the body of the create and update relationship operations

If these versions are specified, the operation is performed only if the current version of the to and/or from records match the specified versions.

Added optional expectedVersion query parameter to the delete relationship operation

If the expected version of the relationship is specified, the operation is performed only if the current version of the relationship matches the specified version.

Added optional details body object parameter to the create relationship and update relationship operations

In this object, provide additional details about the relationship in the form of key/value pairs.

This new object is also returned in responses for the following operations:

• create relationship
• update relationship
• get relationship
• list relationships
• delete relationship
