### Pydantic v1 `regex` instead of `pattern` { #pydantic-v1-regex-instead-of-pattern }

Before Pydantic version 2 and before FastAPI 0.100.0, the parameter was called `regex` instead of `pattern`, but it's now deprecated.

You could still see some code using it:

//// tab | Pydantic v1

{* ../../docs_src/query_params_str_validations/tutorial004_regex_an_py310.py hl[11] *}

```JSON
{
    "name": "Foo",
    "price": 50.2
}
```

/// info

In Pydantic v1 the method was called `.dict()`, it was deprecated (but still supported) in Pydantic v2, and renamed to `.model_dump()`.

    }

    @Test
    @DisplayName("Should handle null configuration gracefully")
    void testNullConfiguration() {
        // When - constructor accepts null config without throwing
        Smb2ReadResponse responseWithNull = new Smb2ReadResponse(null, outputBuffer, outputBufferOffset);

        // Then - response is created successfully

       <version>1.4.0</version>
     </dependency>
     ```

 *  **`Request.Builder` no longer accepts null if a request body is required.**
    Passing null will now fail for request methods that require a body. Instead
    use an empty body such as this one:

    ```java
        RequestBody.create(null, new byte[0]);
    ```

 * **`CertificatePinner` now supports wildcard hostnames.** As always with

      if (entry.getKey() == null) {
        tryDrainReferenceQueues();
        return null;
      }
      V value = entry.getValue();
      if (value == null) {
        tryDrainReferenceQueues();
        return null;
      }

      return value;
    }
