Save the log file from vray(.exe) started as server in a file in the temp folder
Abort rendering on missing asset now works also with missing GI caches
Improved UI when working with sets in VRayToon, VRayDirt, VRayDistance, etc
Added V-Ray shelf with most things from the Create -> V-Ray menu
Print information about the number of lights in the scene to the V-Ray log
More efficient calculation of the AA mask for the progressive rendering
Reduced memory usage with many rectangle lights using the same texture
Ability to add the "Skip render" attribute to VRayObjectProperties node
Adjust the OpenSubdiv attribute names to be different then the standard V-Ray ones
Always clear the frame buffer between frames when the render mask is enabled
Added ability to write multi-part OpenEXR images

Display color corrections (sRGB, LUT etc) are now applied when writing to 8-bit color formats (PNG, JPG etc);
Ability to select the render camera by right-clicking in the VFB window
GLSL
- New built-in functions: sinh, cosh, tanh, frexp, lit, fresnel
VRayVolumeGrid
- New render controls that allow proper rendering of FumeFX imported files
VRayMtl

XGen
Added ability to animate the color of XGen archives through expressions
V-Ray RT GPU
Take into account the AA filter settings as much as possible
ply2vrmesh
added an option to merge two or more .vrmesh files into one
vrimg2exr
The -info option now prints a message if the file is partially written
Added -multiPart option to that produces an OpenEXR 2 file with each render element in its own "part"
Bug Fixes
Transferring assets does not transfer vrsssmap files
EXR textures are always loaded as 32-bit floating point
Low precision of 32-bit tiled EXR
Slow rendering of subdivision surfaces in certain cases
Difference in interpretation of alpha when using files without alpha channel
Connecting an image into RectLight's alpha is not working
Moving a layered texture slot connected to VRayPluginNodeTex crashed Maya
Maya crashed if a scene was loaded while V-Ray was still rendering
Fixed slower rendering when using Maya's Render View compared to using the VFB
Progressive sampling + DR + "Don't render final image" did not finish rendering
V-Ray materials did not respect the display/render layers for the lights in Viewport 2.0
When "Use irradiance map option" of a diffuse material was turned off, Maya crashes
V-Ray crashed when the "Flake map size" option for the FlakesMtl or CarPaintMtl was too large
Fixed various issues with VRayMtl on back-facing surfaces
VRayCarPaintMtl and VRayFlakesMtl with flake glossiness 1.0 resulted in invalid colors
VRayUserColor didn't work with VRayLightMesh and VRayLightMtl material with "direct illumination" enabled
Exporter's memory was not deallocated with hair and "Use camera path"
"Use camera path" produced wrong result when used with "Camera and Aim" after beta 3
The dome camera didn't work with FOV bigger then 165 degrees
Fixed crash with spherical harmonics GI
Fixed wrong rendering with multiple VRaySoftbox textures on the same scene
Fixed crash with renderable curves
Fixed incorrect filter file names for V-Ray nodes in the various dialog boxes
Don't hide the RenderView when pressing the Stop button in the VFB and "Hide Render View" option is disabled
The Pause IPR button of the Render View was not working
The default VFB stamp font was too small on OSX
When proxy Alembic offset was on, animated proxies wouldn't render correctly
Fixed crashes with Embree in specific scene
The VRaySun went wild if moved along the object axis
Save and load dialogs didn't remember their last used paths
Undo didn't work for changing the material connection to VRayMeshMtl
V-Ray RT
Fixed slowdown with render elements when working in the viewport
Fixed random crashes when rendering motion blurred meshes with changing number of vertices
The RT server didn't start automatically on Fedora 20
The RT ignored VRayProxy animation when the timeline was scrubbed
Hiding VRayMetaballs node stopped the RT
Fixed crash if RT is frequently restarted
V-Ray RT CUDA
Fixed wrong VRayDirt in VRayExtraTex RE

Some render elements caused data shift in the wrong channel
The "Invert normals" option of VRayDirt had no effect on backside polygons
