Amazon's free-to-use game engine, Lumberyard, got an update tonight, allowing developers to make it easy for streamers to mess about with overlays.

A new beta version of Amazon’s game engine Lumberyard is now out. The 1.6 build has over 337 new features, fixes, and improvements, but Twitch Metastream is its biggest addition.

The key new feature with the update is Twitch Metastream, which lets streamers customize their stream with overlays of statistics and events from their game session.
