v5.3.1rc1

This release candidate expands layer merging capabilities in Canvas, plus a number of other fixes and enhancements.

Layer Merging

We've expanded layer merging capabilities to all layer types and made one change to the existing Merge Visible operation.

Merge Down (new)

The selected layer and the one immediately below it are merged into a single layer. The two input layers are deleted as part of this process.

Merge Visible (changed)

Previously, in Invoke, Merge Visible deleted all the layers that were merged together.

This has been changed to match image editors like Affinity Photo and PS, where the merged is added as a new layer, leaving all other layers untouched.

Merging Regional Guidance

When merging Regional Guidance, the resultant merged Regional Guidance has no prompt or reference image. It's not possible to merge those settings. Keep this in mind when doing a Merge Down, which will delete the two input Regional Guidance layers.

Merging Control Layers

When merging Control Layers, the resultant merged Control Layer has no model or control settings. Like Regional Guidance, it's not possible to merge the settings, and Merge Down will delete the two input layers.

Control Layers require some special handling. For example, we display them with a "transparency effect" to help you visualize how they stack up. When merging them, we first apply a similar effect to the layer. Specifically, we use the "lighter" blend mode, optimizing for control images with black backgrounds.

All Changes

Enhancements

• Layer merging improvements.
• Updated "What's New" popover.
• Inpaint Mask and Regional Guidance may be saved to assets.

Performance

• Canvas inpaint and outpaint graphs output one less intermediate image, saving one expensive PNG encode (and your disk space).
• Added caches for generation mode calculations in Canvas, providing a substantial reduction in intermediate images created and faster Invoke-to-Queue times.

Fixes

• Canvas alerts prevent clicks on the metadata viewer tabs.
• Save as-ing a Filtered layer may result in the wrong image data being used during generation.
• More resilient Filter handling.
• SDXL T2I OpenPose get get input images in the expected channel order. Thanks @dunkeroni!
• Recall of seamless metadata settings. Thanks @rikublock!

Internal

• Bump diffusers, accelerate and huggingface-hub dependencies to latest versions.
• Refactored CanvasCompositorModule to support new merge capabilities.
