Correct blend time was not always used when backing out of a blend-in-progress.
CinemachineVolumeSettings: changes to Focal Length and Aperture settings were not being applied while auto-focus was enabled.
InheritPosition was not inheriting the camera position in all cases.
Rotation Composer damping was not being applied when the Orbital Follow's Binding Mode was Lazy Follow.
GroupFraming extension did not respect PreviousStateIsValid flag, so could not be reset dynamically.
When blending between a 3rdPerson camera without a look-at target and a camera with a look-at target, the blend was incorrect.
ForceCameraPosition was not working properly for LazyFollow cameras.
Teleporting a camera with a nonzero Target Offset was not smooth.
Exceptions were sometimes generated when an OrbitalFollow component was deleted.

Input Axis Controller was not always reading composite actions correctly.
CinemachineConfiner2D.BakeBoundingShape() was leaving confiner with a not-fully-baked shape.
