 - ``export_mcore_gpt_to_hf`` given a Hugging Face Hub model ID no longer writes the tokenizer, processor, generation config or remote-code files. Pass a local directory instead, e.g. from ``modelopt.torch.export.ensure_local_checkpoint``.
 - Diffusion HF exports now omit attention quantizer buffers by default, except for FLUX.1, which retains enabled Q/K/V ``_amax`` keys for runtime compatibility; other consumers of those keys can opt in with ``export_attention_quantizers=True`` (CLI: ``--extra-param export_attention_quantizers=true``). Disabled attention quantizers remain excluded, and diffusion components, including LTX-2, no longer emit KV-cache quantization metadata.
 - The DFlash2, LiLiCorr, DSpark and Domino training forwards now return their metrics in one ``draft_metrics`` dict of detached 0-dim tensors (call ``.item()`` for a Python float), replacing ``selector_metrics``, ``lilicorr_metrics``, ``dspark_metrics`` and ``domino_metrics``. DSpark's ``ce_loss``/``l1_loss``/``base_accuracy`` are now ``loss_ce``/``loss_tvd``/``backbone_accuracy``, and Domino's ``final_loss``/``base_loss``/``base_accuracy`` are now ``loss_final``/``loss_backbone``/``backbone_accuracy``.
+- DSpark and Domino training now honor ``dflash_loss_objective`` instead of always applying the static ``dflash_loss_decay_factor`` decay, so they train with D-PACE by default. Set ``dflash_loss_objective: decay`` to keep the previous weighting, as the shipped ``dspark.yaml`` and ``domino.yaml`` recipes now do, and finish runs started on an earlier version before upgrading: resuming one restores the objective saved in its checkpoint (``dpace`` unless the run set it) instead of the recipe's.
