- **added** — Added PREFIX AWARE routing strategy and PrefixAwareRoutingConfig to SageMaker CreateEndpointConfig with PrefixLength and ConcurrencyThreshold configuration
- **added** — Added support for the SearchFixtures API and DataSourceConfiguration in ElementalInference to map fixture event data onto clipping outputs
- **added** — Added the PrefixAwareId header to SageMaker Runtime InvokeEndpoint and InvokeEndpointWithResponseStream as a routing hint for prefix-aware routing
- **added** — Added Malay language option to Connect for AI-powered automatic evaluation form filling
- **added** — Added VirtualSourceAddress to MediaLive multicast output destinations for specifying source IP address for outbound multicast packets

* api-change:``sagemaker``: Added PREFIX AWARE routing strategy and PrefixAwareRoutingConfig to CreateEndpointConfig. Configure PrefixLength and ConcurrencyThreshold to route requests that share the same prompt prefix to the same instance.
* api-change:``elementalinference``: Added support for the SearchFixtures API and DataSourceConfiguration, enabling customers to map fixture event data onto clipping outputs for improved feature accuracy.
* api-change:``sagemaker-runtime``: Added the PrefixAwareId header to InvokeEndpoint and InvokeEndpointWithResponseStream. This optional parameter serves as a routing hint for endpoints configured with prefix-aware routing, differentiating routing decisions for requests that share the same prompt prefix.
* api-change:``connect``: Added Malay language option to use AI to automatically fill evaluation forms in Malay
* api-change:``medialive``: Added VirtualSourceAddress to multicast output destinations for MediaLive Anywhere channels. Specifies the source IP address for outbound multicast packets when downstream networks enforce source-IP filtering.
