+
+  Last week, I made a new tag (psphot_dev_08) after finishing the work
+  to clean memory leaks and to modify psphot to work with Paul's
+  ppImage infrastructure.  
+
+  I have added a new background model function which generates a
+  median map based on Robert's suggestion of a) half-step windows and
+  b) linear interpolation.
+
+  Now, I am working to remove the constant sky level concepts and make
+  every relevant test use the signal/noise ratio as the trigger.  This
+  has impacts on the peak detections, the threshold for blends, and
+  the threshold for choosing pixels in the fitting routines.
