This patch mainly fixes the Unity security vulnerability that was disclosed today but also contains some other improvements/fixes.
Fix for CVE-2025-59489, a security vulnerability affecting all Unity-based games. VTube Studio now uses Unity 6000.0.58f2 and is not affected.
Increased maximum VNet model/asset size from 300 to 320 MB to accommodate certain bigger models.
Fix for issue that made VTube Studio freeze intermittently every few seconds/minutes for some users.
Various improvements of per-frame memory usage. Should improve performance especially for larger models.
VTube Studio now automatically makes sure the window cannot be smaller than a certain threshold. This change was made to fix a bug where VTube Studio could become a 1x1 pixel window and crash on startup.
Fixed bug in animation system that caused glitching when using Live2D "inverse step" keyframes in animations.
