YafaRay 3.1.1 is now the recomended version for any kind of use. Changelog and builds at https://github.com/YafaRay/Blender-Exporter/releases/tag/v3.1.1-beta. Discussion thread here.
This release was not backwards compatible with YafaRay 0.1.5 because of the critical color pipeline bug. It was also the last YafaRay version without render passes and render views. More information here.
YafaRay 0.1.5 was a key maintenance release which included important improvements and fixes for long-standing issues such as sampling errors recurrence (black & white dots), new vertex normal calculation for better raytracing on high poly, improved materials behaviour and a better Blender compatibility.
The add-on is installed from Blender, using 'Install Add-on' button in the Addon section, Blender User Preferences window (Ctrl Alt U). In the link below you will find a video about the installation:
If you have a previous version of the add-on installed and you want to upgrade, just be sure the Overwrite tickbox is enabled in the files browser when you are about to select the zip file of the new add-on version.
