[runtimes] Fix physics jitter

[ios][libgdx]premultipliedAlpha Rendering Issue on iOS Compared to Android

Allow linked meshes to be moved to a different slot

Undoing after shifting keys may lose the selected keys

Mesh distortion occurs when meshes are linked to a different skeleton and animations are imported

[4.3-beta]The curves for the keys of Sliders' properties are incorrect in the Graph view

[4.3.39-beta] Dragging order of bones in weights view doesn't change image overlap

[4.3-beta]Transform values are not maintained when bones are moved between skeletons

When opening an old Spine project in version 4.2 or later, the rotation direction is reversed

Adding draw order keys may cause the key buttons next to the slots in the tree view to disappear

[4.3-beta] Irregular bone movement when Wind or Gravity in Physics constraints is not 0 in the setup pose

Selecting a missing attachment while the “Missing images” checkbox is unchecked will display a black image

4.3.19-beta and later versions do not deform vertices correctly when rotating the mesh in Animate mode

4.3.21-beta and later versions no longer allow bone binding to multiple meshes

The mesh deform key button disappears when switching attachments during animation.

The sequence key button may turn orange even if no changes have been made

When the key handles are set to automatic, the curve disappears under certain conditions

Sliders are not applied in animate mode immediately after opening the Spine project

Additive blending of animations with damping keys causes physics to run out of control

In 4.3.15-beta and later, bones selected with the Pose tool exhibit jerky behavior

Mono sound only plays from the left channel

Polygons packing may not pack an image regions correctly if it is referenced by some mesh attachments

Using some hotkeys while tracing a mesh causes the inner vertices of the mesh to be edited

After saving the selection state of the vertices to the selection group, the selection state of the vertices will be lost when the project is saved.

If the parent bone of a slot with keys is different, the keys of the parent bone are imported to a different bone when animations are imported.

Existing pages are not overwritten when the atlas is packed in JPEG format with JSON or Binary format export.

The key button next to the slot can be too delayed to turn back from orange to its original color.

When duplicating multiple bones, the suffix number should take precedence over the order of creating the bones.

When selecting bones with the `Select All` hotkey, the `Select` option of all bones is disabled under certain conditions

Moving bones between skeletons may change the slot order.

Improvement of sorting logic for constraints

Slider curve display takes priority

New slots added to a folder do not follow the draw order animation of that folder

Easier skin merging

CLI parameter to create export settings JSON from a project's last export

Add an option to change the direction of Zoom Drag for stylus users

Solo Slot function

Export the order of bones in the Weights view as nonessential data

Add "per skin" packing

HTML export option

Improve mac application icon

[4.3-beta] Path constraint position animations do not play correctly at runtime when exporting in binary format.

Ctrl/cmd prevents to properly switch tool in edit mesh mode

[PSD Import] Skin names containing another skin name at the end may cause errors

Constrain different transform properties
