Changes

Note, only relatively significant changes to user-visible functionality will be included here. Most recent changes at the top.

20241228

  • The SageAttention nodes can now take advantage of SageAttention 2.0.1 which supports head sizes up to 128.
  • Fixed an issue which prevented SageAttention from applying to models like Flux.

20241122

  • Added the BlehGlobalSageAttention and BlehSageAttentionSampler nodes. See the README for details.

20241103

  • Added the BlehSetSamplerPreset node and sampler presets feature.

20241021

  • Added seed_offset parameter to BlehDisableNoise and BlehForceSeedSampler nodes. This is to avoid a case where the same noise would be used during sampling as the initial noise. Note: Changes seeds. You can set seed_offset to 0 to get the same behavior as before.

20240830

  • Added the BlehBlockCFG node (see README for usage and details).
  • More scaling/blending types. Some of them don't work well with scaling and will be filtered, you can set the environment variable COMFYUI_BLEH_OVERRIDE_NO_SCALE if you want the full list to be available (but you might just get garbage if you try to use them for scaling).
  • Possibly better normalization function (may change seeds). Set the environment variable COMFYUI_BLEH_ORIG_NORMALIZE to disable.
  • TAESD previews should be faster. Also now can dynamically set the number of upscale layers to skip based on the preview size limits. Additionally it's possible to set the max preview width/height seperately - see the YAML example config.

20240506

  • Add many new scaling types.
  • Add enhancements that can be combined with scaling, also apply_enhancement blockops function.

20240423

  • Added BlehPlug and BlehDisableNoise (see README for usage and description).
  • Increased the available upscale/downscale types for BlehDeepShrink.

20240412

  • Added BlehBlockOps and BlehLatentOps nodes.

20240403

  • Added BlehRefinerAfter node.

20240218

  • Added BlehForceSeedSampler node.

20240216

  • Added BlehModelPatchConditional node (see README for usage and description).

20240208

  • Added BlehInsaneChainSampler node.
  • Added ability to run previews on a specific device and skip TAESD upscale layers for increased TAESD decoding performance (see README).

20240202

  • Added BlehDiscardPenultimateSigma node.

20240201

  • Added BlehDeepShrink node (see README for usage and description)
  • Add more upscale/downscale methods to the Deep Shrink node, allow setting a higher downscale factor, allow enabling antialiasing for bilinear and bicubic modes.

20240128

  • Removed CUDA-specific stuff from TAESD previewer as the performance gains were marginal and it had a major effect on VRAM usage.
  • (Hopefully) improved heuristics for batch preview layout.
  • Added maxed_batch_step_mode setting for TAESD previewer.
  • Fixed reversed HyperTile default start/end step values.
  • Allow only applying HyperTile at a step interval.
