MAX changelog updates:

  • Extended Nemotron-H with the Nemotron-3-Nano-30B-A3B hybrid MoE variant (a
    sigmoid-plus-bias top-6 router over 128 routed experts plus a shared expert)
    and enabled the Nemotron-H architecture on Apple silicon GPUs in bfloat16.
    The MoE path on Metal uses an integer-domain expert-gather index
    (ops.floor_div, avoiding a 64-bit-float divide) and a 32-bit
    moe_create_indices atomic (Apple GPUs lack 64-bit atomics), and adds an
    Apple FP4 (W4A16) decode GEMV with an f16-domain E2M1 decode plus a
    redesigned varlen causal-conv1d kernel. Verified on M5: the 30B-A3B MoE
    serves in bfloat16 at GSM8K 8-shot ~0.85.

Mojo changelog updates:

  • [mojo-lang] polish: Make @explicit_destroy used only for setting error message
