+Release 1.7.3 -- 1 Jul 2016 (compared to 1.7.2)
+--------------------------------------------------
+* ShadingSystem attribute "userdata_isconnected", if set to a nonzero
+  integer, causes a shader call to isconnected(param) to return 1 if the
+  parameter is potentially connected to userdata (that is, if lockgeom=0
+  for that parameter). This if for particular renderer needs, and the
+  default remains for isconnected() to return 1 only if there is an
+  actual connection. #629 (1.8.0/1.7.3)
+* oslc now will warn when assigning the result of a "comma operator",
+  which almost always is a programming error where the shader writer
+  omitted the type name when attempting to construct a vector or matrix.
