The updates you're asking about introduce several improvements and new features to Spine:
Region sequences use the size of the setup frame: This means that when you're working with sequences of images (like a walk cycle), the size of each image in the sequence will be based on the size of the image you have set up in the setup pose. This ensures consistency in the size of your animated elements across the sequence.
Show up to 10 skin names in the tree annotation tooltip for skins: When you hover over the skin placeholder in the tree, a tooltip will show the names of up to 10 skins. This is helpful for quickly seeing which skins are associated with a particular placeholder without having to click through each one.
Synchronize the first and last graph curve handles for looping animations: For animations that loop, this feature ensures that the handles of the graph curves at the beginning and end of the animation are synchronized. This makes the loop smoother by ensuring the motion at the end of the loop transitions seamlessly into the beginning.
Select only rootmost tree nodes after duplicate: When you duplicate items in the tree, only the top-level (rootmost) nodes of the duplicated items will be selected. This makes it easier to move or modify the duplicated group as a whole without affecting the internal hierarchy.
Added keying bone transform inheritance: This is a significant update that allows animators to key the inheritance of bone transforms. This means you can animate whether a bone inherits its position, rotation, and scale from its parent bone or not, offering much more control over the animation.
Snap to the center of edges in edit mesh mode: When editing meshes, this feature allows vertices to snap to the center of edges, making it easier to create symmetrical or precisely aligned mesh deformations.
These updates collectively enhance the flexibility, control, and efficiency of animating in Spine, making it easier to create complex animations and effects.
