For example, if a field in a wrapped request has a literal value of "foo", we will now set that value as the default value for the field. Note that wrapped requests are just a bag of properties that include body properties. ## 1.9.20 **`(fix):`** Support literals in wrapped requests (). For example, if a field in a wrapped request has a literal value of "foo", we will now set that value as the default value for the field. Note that wrapped requests are just a bag of properties that include body properties. ## 1.9.19 **`(fix):`** Fix serialization of enum path parameters. Previously, enum path parameters were serialized using their C# enum name, but now they are correctly serialized using their wire value. ## 1.9.18 **`(fix):`** Fix serialization of enum path parameters. Previously, enum path parameters were serialized using their C# enum name, but now they are correctly serialized using their wire value. ## 1.9.17 **`(fix):`** Support required literals. For example, if a field has a literal value of "foo", we will now set that value as the default value for the field. ## 1.9.16 **`(fix):`** Required client parameters that are headers are now sent when making API requests. For example if a bearer token is required to instantiate the client, we will ensure that it is sent when making API requests. ## 1.9.15 **`(fix):`** Change unpaged endpoints from internal to private to avoid ambiguous references in test projects who have access to internals. **`(fix):`** Fix an issue where enum values named `Equals` would always have be converted to `"Equals"` instead of their correct wire value. **`(feat):`** Increase test performance by parallelizing tests and setting HTTP request retry delay to 0.
