The headline change of this release is a complete rewrite of the core CPU: the CPU is now implemented entirely in Rust and serves as the only implementation, with the previous C++ 6502 core removed. The rewritten core brings further improvements in emulation accuracy and runtime stability, supporting every official instruction along with 109 unofficial opcodes, with the nestest suite matching instruction-for-instruction at 5000/5000. Save states created in earlier versions remain fully compatible with the new core, so no conversion is needed. For quality assurance, the built-in KagamiQA test system automatically runs regression and hardware-accuracy checks on every push.

本版本最重要的变化是核心 CPU 的全面重写：CPU 现已由 Rust 实现并成为唯一实现，原先的 C++ 6502 内核被正式移除。重写后的内核在模拟精度与运行稳定性上进一步提升，全部官方指令与 109 条非官方指令均得到支持，nestest 逐指令测试达到 5000/5000 完全匹配；同时，旧版本创建的存档仍可无缝用于新内核，无需任何转换。质量保障方面，内置的 KagamiQA 测试系统会在每次提交时自动执行回归与硬件精度校验。
