 For example the most recent "grand reprocessing" of the 3PI survey is identified with

+the '''IPP_RELEASE''' 3PI.PV1. If a user requests stamps from a particular position
 on the sky, images will be selected from 3PI.PV1 for exposures that were included
 in that release. Images will be selected from the 3PI.nightly release for
 exposures that were observed after the processing for 3PI.PV1 was done.
 
+'''RUN_TYPE''' is a new column used to narrow searches for stack and diff images. For stacks
+this value is only used if the release system is used to select stacks. When supplied
+it restricts stacks to particular types. Valid values are: deep, reference, nightly, and notnightly. 
+
+For diff images valid values are warp_warp, warp_stack, and stack_stack.
+
+The final new columns are '''FWHM_MIN''' and '''FWHM_MAX'''.  These may be used to 
+restrict selected images to a range of measured seeing. For stacks this is only available
+for released stacks that have been calibrated by running staticsky and skyceal stages.
+
+The units of the fwhm values are pixels: ~.258 arcseconds per pixel for single frame images
+and .25 or .258 depending on the tessllation for stacks and diffs.
+
+The values are compared to the fwhm_major columns in the ipp database. For raw, chip, and warp
+images these values are compared to camProcessedExp.fwhm_major. For stacks it is the fwhm_major
+value in the skycalResult table.

+=== Sources from postage stamps ===
+When sources are requested the system now returns a cmf file containing only the sources from
+the region of interest. Previously it returned a copy of the entire input cmf. 
+
+For stacks sources from the staticsky/skycal stages are returned if the stack is marked as calibrated in
+the release tables.  Previously it returned the cmf from the stack stage which were sources detected
+in the input exposures and thus not particularly useful
