v0.5.1
0d41415

runNburn 0.5.1 is a compatibility patch for the v0.5.0 release. It fixes two model paths discovered while running the standard four-model suite on Apple M5 Pro without changing model formats or CUDA kernels.

Fixes

  • Retain model-owned F32 weight storage used by Metal NoCopy buffers. This fixes the storage-lease panic in Qwen3.6 in-model MTP after F16 or quantized weights are converted to F32. Registration is compiled only when the Metal feature is enabled.
  • Reject unsupported AArch64 Q2_K prequantized Q8K dispatch. Q2_K now uses the existing F32 or fused NEON path instead of panicking, while the existing Q8 fast paths for Q4_0, Q4_1, Q5_0, Q5_1, Q8_0, and Q8_1 remain intact.

Verification

  • Workspace test suite: 1,659 passed, 205 ignored.
  • Host build matrix: CPU, CUDA, Vulkan, OpenCL, MediaTek, and Metal combinations passed.
  • Release product checks and the v0.5.1 binary version smoke passed.
  • Qwen3.6 Metal MTP and Hy3 Q2_K reproductions completed successfully; the Apple M5 Pro standard four-model suite completed with stable correctness hashes or token IDs.
