  • Blender NURBS Surface objects are now exported (as mesh data) (1cdf15ae4f)

Images

  • OpenEXR: Faster writing of half-precision (FP16) EXRs. (PR#157874)

Movies

  • Stereoscopic metadata is exported. No need to post-process the video for correct playback in video players. (5635567dad)
  • Panoramic camera metadata is exported. Only full equirectangle cameras are supported. (0d98bf9ff6)

Alembic

  • Added support for importing non-animated and animated object visibility. Animations are imported as F-Curves. (PR#157983, PR#158321)
  • Added support for importing animated camera data as F-Curves (PR#158321)
  • Original coordinates for subdivision meshes are now imported (PR#159195)
  • Topological changes for subdivision meshes are now properly detected (PR#159195)

STL
