+**Breaking Changes:**
+- :warning: (all, [smithy-rs#4120](https://github.com/smithy-lang/smithy-rs/issues/4120)) Update MSRV to 1.82.0
+
+**New this release:**
+- :bug::tada: (client, [smithy-rs#4074](https://github.com/smithy-lang/smithy-rs/issues/4074), [smithy-rs#3926](https://github.com/smithy-lang/smithy-rs/issues/3926)) Promote `aws-smithy-mocks-experimental` to `aws-smithy-mocks`. This crate is now a recommended tool for testing
+    generated SDK clients. This release includes several fixes as well as a new sequence builder API that can be
+    used to test more complex scenarios such as retries.
+
+    ```rust
+    use aws_sdk_s3::operation::get_object::GetObjectOutput;
+    use aws_sdk_s3::config::retry::RetryConfig;
+    use aws_smithy_types::byte_stream::ByteStream;
+    use aws_smithy_mocks::{mock, mock_client, RuleMode};
+
+    #[tokio::test]
+    async fn test_retry_behavior() {
+        // Create a rule that returns 503 twice, then succeeds
+        let retry_rule = mock!(aws_sdk_s3::Client::get_object)
+            .sequence()
+            .http_status(503, None)
+            .times(2)                                            // Return 503 HTTP status twice
+            .output(|| GetObjectOutput::builder()                // Finally return a successful output
+                .body(ByteStream::from_static(b"success"))
+                .build())
+            .build();
+
+        // Create a mocked client with the rule
+        let s3 = mock_client!(
+            aws_sdk_s3,
+            RuleMode::Sequential,
+            [&retry_rule],
+            |client_builder| {
+                client_builder.retry_config(RetryConfig::standard().with_max_attempts(3))
+            }
+        );
+
+        // This should succeed after two retries
+        let result = s3
+            .get_object()
+            .bucket("test-bucket")
+            .key("test-key")
+            .send()
+            .await
+            .expect("success after retries");
+
+        // Verify the response
+        let data = result.body.collect().await.expect("successful read").to_vec();
+        assert_eq!(data, b"success");
+
+        // Verify all responses were used
+        assert_eq!(retry_rule.num_calls(), 3);
+    }
+    ```
+- :bug: (all, [smithy-rs#4117](https://github.com/smithy-lang/smithy-rs/issues/4117)) Fix a bug where fields that were initially annotated with the `required` trait and later updated to use the `addedDefault` trait were not serialized when their values matched the default, even when the values were explicitly set. With this fix, fields with `addedDefault` are now always serialized.
