We are happy to announce Unity 5.6.1p4. The release notes and the corresponding issue tracker link for issues fixed in this release are as shown below.

As always, patch releases are recommended only for users affected by those bugs fixed in that patch.

Improvements

Android: Enabled NEON in Umbra.

UI: CanvasRenderer::OnTransformChanged will not be called when object is inactive. (815861)

Video: Optimized video decoding directly into RenderTexture if it is the same size as the video stream

Video: Skip-ahead functionality improvements.

Changes

GI: Added support for LOD baking in Progressive Lightmapper. Light Probes are not necessary anymore when baking LODs using Progressive Lightmapper.

GI: Support for double sided materials in Progressive Lightmapper. Added a new material setting that causes lighting to interact with backfaces. When enabled, both sides of the geometry get accounted for when calculating Global Illumination. Backfaces do not count as invalid when seen from other objects. Backface rendering is not controlled by this setting nor will backfaces be represented in the lightmaps. Backfaces bounce light using the same emission and albedo as frontfaces.
