+ACSTOOLS
+--------
+
+ACSTOOLS v2.0.0 Release Notes
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+*2016-03-17 16:37:53+00:00*
+
+The following changes were made since the last release in April 2014:
+
+-  Removed standalone ``PixCteCorr`` task. Use ACSCTE step from HSTCAL
+   instead to have parallelization and consistent results with the
+   CALACS pipeline.
+
+-  Removed ``runastrodriz`` task (moved to ``drizzlepac``).
+
+-  Added masking, post-flash processing, iterative cleaning, and
+   alternative statistics to ``acs_destripe`` task. Masking is
+   particularly useful for polarized data.
+
+-  Fixed bugs in ``acs_destripe`` task, including proper error handling
+   and pixel weighting.
+
+-  Added new ``acs_destripe_plus`` task, which is particularly useful
+   for destriping subarrays with ``acs_destripe`` in the middle of
+   CALACS processing (between ACSCCD and ACSCTE steps).
+
+-  Added new ``satdet`` module, which can detect and flag satellite
+   trails.
+
+-  Added Python 3 support (untested).
+
+DRIZZLEPAC
+----------
+
+Public Release of v2.1.3
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+*2016-04-05 19:23:04+00:00*
+
+This version represents the same code, with a few additional
+enhancements, as the code that was installed for operational calibration
+of HST data as of 23 Feb 2016. This represents a major update to the
+DrizzlePac software, and also the last version with significant new
+features. Future releases will focus primarily on bug fixes that affect
+operational use of this code. Full support for this package can be found
+at http://drizzlepac.stsci.edu.
+
+A brief overview of the new features and major bug fixes found in this
+version (relative to what was released as part of v1.1.16) includes:
+
+-  Full Python 2.7 and 3.5 support
+
+-  Built-in support for automatic mosaic creation
+
+-  Tweakreg now aligns all images in a mosaic into a single undistorted
+   output frame even if some images do not overlap others in the mosaic
+
+-  Improved sky matching
+
+-  Produce seamless mosaics using new sky matching techniques. More
+   details can be found in an example where these techniques are
+   compared.
+
+-  Support for the improved time-dependent ACS distortion model
+
+-  Supports the new ACS distortion calibration: Only DrizzlePac 2.0 is
+   able to interpret and apply the latest ACS/WFC distortion reference
+   files
+
+-  Support for alignment of data from different HST cameras
+
+-  Specify separate source finding parameters for input and reference
+   images to optimize source detection from images taken with different
+   HST cameras.
+
+-  Support for use of inclusion/exclusion regions in image alignment
+
+-  Improved support for WFPC2 data
+
+-  resolved problems processing WFPC2 data which had DGEOFILEs
+   specified.
+
+-  now requires user to run 'updatewcs' task on WFPC2 data to enable
+   astrodrizzle and tweakreg to work with them seamlessly
+
+-  **[API change]** Use of 'updatewcs' removed from TEAL interfaces
+
+-  User and pipeline will need to run this task independently prior to
+   running astrodrizzle or tweakreg
+
+-  Python scripts calling astrodrizzle and tweakreg can still set the
+   'updatewcs' parameter and have it run as part of those tasks
+   (presumably, the user understands when this task will wipe out
+   previous updates in their own script)
+
+-  **[API change]** The user interfaces to all 3 coordinate
+   transformation tasks now use 'coordfile' as the input file of
+   coordinates to transform. The use of 'coords' has been deprecated,
+   but still can be used if needed. However, use of 'coordfile' will
+   always override any input provided simultaneously with 'coords'
+   parameter. Help files have been updated to document this as clearly
+   as possible for users.
+
+-  Now relies on astropy for WCS, coordinate specification and I/O
+   libraries
+
+-  A full 6-parameter general linear fit can now be performed using
+   tweakreg, in addition to shift and rscale
+
+-  WCS keywords updated by tweakreg will result in an undistorted output
+   frame with NO residual skew (as represented in the CD matrix
+   keywords)
+

+FITSBLENDER
+-----------
+
+Public Release of v0.2.6
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+*2016-04-05 19:35:00+00:00*
+
+This version of fitsblender supports the release of drizzlepac v2.1.3 as
+used in the operational HST calibration pipeline and archive as of 23
+Feb 2016. It primarily includes bug fixes; namely,
+
+-  Fixed problem with random results from fitsblender by replacing use
+   of dict with OrderedDict. This problem resolves issues with which
+   image was interpreted as first and last when looking for values to
+   use to populate the combined header.
+
+-  Default pipeline processing rules files for all instruments amended
+   to reset FLASHCUR header value to 'multi' instead of first.
+
+-  Simple update to insure that any keyword deletion works cleanly with
+   astropy by trapping any KeyError? exceptions explicitly.
+
+-  Replace use of pyfits with astropy.io.fits.
+
+-  Now works as-is under Python 2.7 and Python 3.5
+
+HSTCAL
+------
+
+HSTCAL v1.0.0 Release Notes
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+*2016-03-17 17:46:33+00:00*
+
+The following changes were made since the last release in April 2014,
+broken down by sub-components:
+
+General
+^^^^^^^
+
+-  Fixed compilation warnings.
+
+WFC3 (v3.3)
+^^^^^^^^^^^
+
+-  A new processing step, FLUXCORR, was added to the UVIS pipeline, and
+   is performed at the end of processing. It will scale the chip2 image
+   using the new PHTFLAM1 and PHTFLAM2 values in the IMPHTAB. New flat
+   fields for all filters, as well as a new IMPHTTAB have been delivered
+   by the team for this step to be completely implemented.
+
+-  The CTE correction has been implemented for all full-frame UVIS data.
+   This is done in conjunction with a full run through of the pipeline
+   code without the CTE correction applied, such that both CTE corrected
+   and non-CTE corrected output files are saved. This correction is for
+   the same reasons as in ACS, but the CTE correction algorithm is
+   different; it is applied to the raw file instead of later in the
+   processing. Some sections of the CTE code support parallel processing
+   with OpenMP. The default for calwf3 is to use all available
+   processors. To restrict processing to 1 cpu use the flag -1 in the
+   call to calwf3.e The CTE processing is controlled with the PCTECORR
+   keyword. New CTE corrected output products will be produced at all
+   stages which involved changes to most of the controlling routines and
+   output trailers. See the team documentation for more complete
+   information on the updates.
+
+-  In conjunction with the CTE correction, a standalone interface
+   ``wf3cte`` was created to perform just the CTE correction, similar to
+   ``wf32d`` etc.
+
+-  Sink pixel detection is now performed in the UVIS pipeline for
+   full-frame images, using the SNKCFILE reference image, and the
+   science data DQ mask is updated with the detections. The reference
+   image has 2 extensions, each in the pre-overscan trimmed format. This
+   step is performed if DQICORR is PERFORM, and is done before BLEVCORR
+   while the science image is still untrimmed.
+
+-  Some of the new reference files required new code to read them,
+   including the new format for the UVIS IMPHTTAB associated with the
+   FLUXCORR step
+
+-  The default CRCORR behavior for IR SCAN data will now be set to OMIT
+   by default so that the resulting calibrated image is last read -
+   first read instead of the fit to the ramp.
+
+-  All IR scan related keywords formerly in the SPT file will also be
+   present in the FLT file
+
+-  For UVIS and IR, a copy of the CSMID keyword, formerly in the SPT
+   will also be in the FLT file, CSMID lists the channel select
+   mechanism ID.
+
+-  bug fix: nrej initialized in ``wf3rej`` so that REJ\_RATE reported
+   consistently correct for the IR pipeline
+
+-  bug fix: a wfc3 uvis association which specifies multiple products
+   wont finish processing and segfaults
+
+-  An assortment of memory leaks were fixed
+
+-  Explicit error added to report a non-WFC3 image used as input to the
+   pipeline
+
+-  updated text in ``wf3rej`` to report that Astrodrizzle should be used
+   to align images instead of PyDrizzle since that’s how it’s advertised
+   to users
+
+-  fixed SEGFAULT error in reference file checking when iref environment
+   variable not set by user, so can’t find file
+
+ACS
+^^^
+
+-  Added support for 2K subarrays in PCTECORR.
+
+-  ``acs2d.e`` reads calibration flags from image header instead of
+   command line.
+
+-  Improved temporary file handling.
+
+-  Improved error message if input image does not belong to ACS.
+
+-  Added support for very long input list for ACSREJ.
+
+-  Fixed memory leaks (non-critical).
