- 2Enhanced multiplayer security for host kicking and banning operations to prevent malicious exploits
All Changes
⚙️Performance & Tech Stack(1)
- fixThreading Libraries: Updated threading libraries to improve performance on modern hardware configurations, specifically targeting CPUs with high core/thread counts and heterogeneous architectures.
🌐Multiplayer(1)
- fixMultiplayer: Increased hardening for host operations such as kicking and banning players to prevent malicious interactions.
Summary
Technical Infrastructure Update
This second Summer Open Beta update focuses on the game's tech stack rather than gameplay balance. The primary change involves updating the threading libraries to better support modern CPUs, particularly those with high core counts and heterogeneous architectures (such as P-cores and E-cores).
Multiplayer Security
Developers have also implemented "MP hardening" to secure host operations. This specifically targets the kicking and banning of players to prevent malicious interactions reported by the community. Balance changes and experimental gameplay adjustments are expected to resume in future beta updates.
