The Lattice SDK now supports streaming entity updates in real-time using the REST API across all supported languages:

* Added [`StreamEntities`](/reference/rest/entities/stream-entities) API for establishing persistent connections to stream entity events
* Implemented examples for streaming entities in Go, Java, Python, and TypeScript
* Updated documentation to demonstrate both basic streaming and component filtering

## New features

The new `StreamEntities` API provides several configurable parameters:

* **`preExistingOnly`**: Controls whether to stream only existing entities or include real-time updates.
* **`heartbeatIntervalMS`**: Configures how frequently the server sends heartbeat events.
* **`componentsToInclude`**: Allows filtering which entity components are streamed, reducing bandwidth usage and improving performance.

## Documentation updates

As a part of this release, [Watch entities](/guides/entities/watch) guide has been updated with code examples in all supported languages.
Each example demonstrates both basic entity streaming and filtering specific components, providing common patterns for integrating
real-time entity data into your Lattice apps.
