-3.6.1 (15-Jun-2023)
-===================
 
-- Fixed an incompatiblity in the ``minmed`` code for cosmic ray rejection
-  with the ``numpy`` version ``>=1.25``. [#1573]
+3.6.2rc0 (unreleased)
+=====================
 
-- Fixed projection cell identification in overlapping regions. [#1572]
+- Removed the version restriction on matplotlib. [#1649]
+
+- Forced a preferential order on the final selection of the WCS solution 
+  from the common pool of solutions among all input exposurea.  All input images 
+  need to have the same WCSNAME (same WCS solution) when performing pipeline 
+  alignment to avoid imprinting differences from one catalog to another on the 
+  final fit and destroying the relative alignment. [#1645, #1638]
+
+- Redesigned the overall structure of the documentation, readthedocs, for the
+  package. [#1620]
+
+- Addressed a bug in the calculation of measurements for each detected source
+  in the filter catalogs. The detection catalog, based upon the "total" image,
+  is now used in the correct manner to define the source centroids and shape 
+  properties.  In addition, these properties are used to perform aperture 
+  photometry. [#1614]
+
+- Updated the HAP drizzle parameters for WFPC2. The primary change includes 
+  changing skymethod='localmin' from the prior 'match' which did not work well 
+  for the overlapping chips. [#1617]
+
+- Corrected reference catalog weights from being proportional to sigma to
+  the proper 1/sigma**2. [#1616]
+
+- Removed the use of the shadow mask as an initial step in addressing the WFPC2 
+  chip gaps [#1551]
 
 - Fixed a bug in processing of the ``group`` argument due to which the code
   would crash when ``group`` would be an integer number or a list of numbers.
   Also, added support for specifying extensions as tuples of
   ``(extname, extver)``. [#1612]

 - 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
