What's new

LightSpeedRe 2.0.2hotfix

  • Keep ModernFix's audit and cleanup on the render thread when class initialization can require an OpenGL context.
  • Preserve Lightspeed's configured cache and concurrency flags when LightLoad is installed.
  • Move LightLoad class-archive compression and publication off the render thread. The original archive is still written, and shutdown waits for completion.
  • Preserve resource-output callback exceptions without repeating the callback through a fallback scan.
  • Use bounded neutral resource caches and atomic file publication. Old Java object caches are ignored and rebuilt; current lookup results take precedence over asynchronous disk loads.
  • Correct the known JDTE spawner accessor descriptor while retaining its original Mixin callbacks.
  • Keep the LightLoad reflection ABI without enabling the duplicate initial-pack-preload path.
  • Remove saved Lightspeed bootstrap arguments from the current launcher profile while preserving user arguments and worker settings. Normal startup uses native mod loading without automatically installing or attaching a JVM agent.
  • Retain the completed mod-loading and initial-resource-reload requirement for title-ready logging.

Existing startup optimizations remain enabled. No fixed startup time or universal percentage improvement is claimed.

中文

  • 保留 ModernFix 审计和清理,在需要 OpenGL 上下文时使用渲染线程。
  • LightLoad 共装时保留 Lightspeed 自身配置的缓存与并发优化。
  • 类字节归档压缩和发布移至缓存线程,原始写回保留,退出等待完成。
  • 资源输出回调异常原样传递,避免回退扫描重复调用。
  • 使用受限中立缓存与原子发布;旧对象缓存忽略并重建,异步读取不覆盖当前查询结果。
  • 修正已确认的 JDTE 生成器访问器类型,保留原 Mixin 回调。
  • 保留 LightLoad 反射 ABI,不恢复会重复派发初始加载阶段的资源包预加载路径。
  • 清理当前启动器配置中本项目遗留的启动参数,保留用户参数和工作线程设置;普通启动不自动安装或附加 JVM Agent。
  • 标题就绪仍要求模组加载和首次资源重载完成,保留现有核心优化。
