 Taoning added genssky -L option to specify global and diffuse
 illuminance values for output calibration.
+
+Created C++ class for rcontrib and example tool rxcontrib, which
+is an optional compile in the src/rt directory.  The output
+model is more general in some respects and the operations more
+efficient, but standard output is not supported, nor is ASCII
+results data.
+
+Added strnstr.c compatibility module in ray/src/common, since
+it isn't present on Linux derivatives.
+
+Added WGMDfunc material type with programmable roughness and
+separate modifier paths for the different components.
+
+Added gensurf -i option at the request of Peter Apian-Bennewitz
+to reverse surface normals, mostly for data input, when it is
+a bit more difficult to adjust.
+
+Added rad -N option to rholo call for multiprocessing when
+mkillum and/or mkpmap are involved in octree prep.
+
+Added ability of gendaymtx to read EPW as well as WEA files.
+When EPW input is provided, the 3-hour average dew point is
+used to compute a more accurate precipitable water content
+value.  It currently does not use these data directly from
+the EPW input, relying instead on a dew-point-to-W calculation.
+This follows the request and recommendations of David G-M.
+
+Removed limitation in rfluxmtx, which was disallowing distant
+and local receivers. Found this to be a perfectly valid approach
+for some annual daylighting scenarios.
