Bones

• The Inherit Scale checkbox is replaced with a dropdown providing more options, e.g. Inherit Average Scale. (fcf2a712)

Drivers

• Support overriding the Euler order and access Quaternion values in rotational Transform Channel driver variables. (82ef1edc, 88370639)
• Swing + Twist rotation decomposition to Transform Channel driver variables. (e91ea20e)

Constraints

Copy Scale

• New option to force the copied scale to be uniform. (49729785)

Copy Rotation

• Option to explicitly specify the Euler order used during copy. (18d4ad5a)
• Replaced the Offset checkbox with a Mix dropdown providing better combining options. (f4056e9e)

Copy Transforms

• Added a new Mix dropdown option that allows combining the original and copied transforms. (f8362836)

Transformation

• Options to explicitly specify the input and output Euler order. (18d4ad5a)
• Swing + Twist rotation decomposition as a choice for rotation input mode. (e91ea20e)
• Mix dropdown option that allows changing how the transformation is combined with the original. (e858d21a)

Custom Properties

• Custom property UI now supports short arrays, useful for storing vectors or colors as a single property. (aef08fda)
• Array custom properties can be set to appear as a standard color picker button in the UI. (55c38f47)
