Here's the skinny on the patch according to VersionTracker:

What's new in this version:

• Artifacts occasionally appeared on transparent objects when using lights that have soft shadows
• Bitmap sequence output was only rendering one frame of a network rendered animation. NOTE: Images are not assembled until after the animation render has been completed, so you will not see any image files until the animation sequence has finished rendering
• Many bad things that were happening in the Tree Lab
• Metaballs and grouping workflows were leading to crashes
• Camera tracking problems and associated crashes have been addressed
• The clipping bracket in the terrain Editor was acting strange on occasion
• A persistent and annoying row of white pixels at the top of the Terrain Canvas in the Terrain Editor was sometimes produced
• The Light Lab no longer explodes when playing with animation there
• Update and feedback in the Network Render Manager has been substantially improved
• Depth of Field and Panoramic rendering now play well together

Hope this helps!
