-3.6.0rc1 (10-May-2023)
+3.6.1rc0 (15-Jun-2023)
 ======================
 
+- Force the version of matplotlib to be <= 3.6.3 as the newer versions of
+  the library cause problems with the calcloud preview generation.  This
+  is a temporary restriction.
+
+3.6.0 (12-Jun-2023)
+======================
+
+- Modified the pyproject.toml file to ensure the tweakwcs version is greater
+  than 0.8.2 as the issue of taking a very long time to compute the bounding 
+  polygon now defaults to an approximate method which is significantly faster.
+  [#1565]
+
+- Modified Projection Cell 0 declination coordinate of the center to be
+  -89.999999999997 and the Projection Cell 2643 declination coordinate to
+  be 89.999999999997 to shift the WCS CRVAL position slightly off the pole.
+  [#1560]
+
+- Modified the criteria for the rejection of catalogs based upon the cosmic
+  ray criterion.  An empty catalog (n_sources=0) should not be rejected by the
+  CR contamination.  Also, if a catalog is empty, it should not trigger the
+  rejection of the other "type" of catalog (type=point vs segment). [#1559]

 - Turn off use of ``verify_guiding()`` for WFPC2 images only as its use
