===================
- At this time pin Astrocut to versions <=0.9 to avoid conflicts with urllib3
package. [1689]
- Added functionality to allow the use of a two-column poller file. This is used
to update the WFPC2 SVM aperture header keywords from the values in the poller
file. [1683]
- 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]
