****************************************************************************
*                               Qt 5.10.0 Changes                          *
****************************************************************************

Qt3DAnimation
-------------

 - Added a tech preview of the skeletal animation system. Use the
   QSkeletonMapping type to map animation clip channels onto joints of
   a skeleton.

 - Bugfix:
   * The backend node (`Qt3DAnimation::Animation::Clock`) had an incorrect
     return type specified (`int` instead of `float`) which was narrowing
     the actual value during the evaluation of associated animation clips.

 - General:
   * Introduce the QClock frontend and backend nodes to control animator
     playbackspeed.

Qt3DCore
--------

 - General:
  * Added support for SIMD instructions to accelerate matrix and vector
    operations within Qt 3D. At present, SSE2 and AVX2 are supported. By
    default, SSE2 instructions are enabled. To additionally enable the use
    of AVX2 instructions, configure with the -qt3d-simd avx2 option.
    Passing -no-sse2 disables SSE2 use in QtCore, QtGui and Qt3D.
    Configuring with -no-qt3d-simd disables SIMD in Qt 3D only.

  * Added support for loading skeletons from glTF 2 files.


Qt3DRender
----------

 - New additions:
  * Added a framebuffer blit frame graph node

  * Added a promity filter frame graph node

  * Added support for sprite sheets

  * Added QCamera::viewAll()

  * Introduced shader graphs: dynamically generate fragment shaders
    from graph based description.

  * Added Scene2D: embed Qt Quick content into Qt 3D and interact with
    it.

  * Added support for rendering skinned meshes via the new QArmature
    component. Can be animated with the animation aspect and the
    QSkeletonMapping type.

  * Added support for loading mesh data from glTF 2 files.

 - General:
  * Improved QLayerFilter

Qt3DInput
---------
 - Added support for point and line picking

Qt3DExtras
----------

 - Added Qt3DExtras::QAbstractCameraController abstract base class to make
   implementing new camera controllers easier.
