Improbable presented a new version of their toolkit. 

Improbable noted that they have been working on this update largely remotely because of the Coronavirus situation since the release of the 2020.1 update in March. The update offers improvements and optimizations to AI Offload, so it's playtest-ready for developers. The feature was co-developed with Midwinter Entertainment, an Improbable game studio behind upcoming game Scavengers that uses AI Offload with Unreal Engine to populate a systems-heavy game world with 60 human players and a 5-to-1 AI to player ratio.

SpatialOS for Unreal 2020.2:

• Playtest-ready AI Offload: AI Offload enables developers to run their AI logic on a second game server.
• Performance improvements: Version 0.10 of the GDK for Unreal delivers performance improvements that drive down latency and bandwidth use as well as bug fixes and workflow improvements.
• Updated pricing structure: Updated pricing model to make it clearer, flexible and more cost-efficient for most types of games.
• Zoned Servers (preview): Now evaluation-ready for games launching in H2 2021 and beyond. 
• iOS and Android support (preview): Documented and supported workflows for teams developing and playtesting on iOS and Android.
