    NEWS file updated until commit 12ed388
    
    All the commits after the 0.0 release version were inspected and the
    respective sections of the NEWS file were filled based on the most
    significant user-visible changes. It will be finalized (release date
    included) when the official release tag is created.

 * Noteworthy changes in release 0.1 (YYYY-MM-DD) [stable]
+* << Until commit 12ed388 Corrected imgcrop/imgpolygon.sh test script >>
+* <<          REMOVE THESE TWO LINES BEFORE THE 0.1 RELEASE           >>
 
 ** Bug fixes
 
+  MakeCatalog's problem in checking the sizes of all input images is now
+  fixed.
+
+  NoiseChisel's problem with reading the `--kernel' option is now
+  corrected (bug #46750).
+
+  lib/mesh.c's problem in correctly calculating the mesh sizes was
+  corrected (bug #47611).
+
+  `make check' will not look into system utility configuration files. In
+  the previous release, if Gnuastro was already installed, the
+  configuration files already present on the system would also be read. Now
+  only configuration files in the tested package are used (bug #47833).
+
+  Ghostscript's version is now checked at configure time after its
+  existence. ConvertType uses the `-dPDFFitPage' option to Ghostscript
+  which was introduced in version 9.10, so older versions would pass
+  configure but at `make check' time, the PDF test would fail. Now this
+  test is skipped (bug #47868).
+
+  Most tests would fail when `make check -jN' was run (to do the checks on
+  N threads). A dependency structure has now been defined to fix this
+  problem and greatly speed up the testing process (bug #47957).
+
 ** New utilities
 
+  Arithmetic: For arithmetic operations on the pixels of input images. With
+  this utility, it is now possible to add multiple images with each other,
+  or easily calculate a median image. It as a large set of other arithmetic
+  operations and some functions which can be done on the input image(s). An
+  unlimited number of input images can be given, the images will only be
+  loaded when necessary and will be freed as soon as they are no longer
+  necessary.
+
+  CosmicCalculator: For doing cosmological calculations at a given
+  redshift.
+
 ** New features
 
+  All the utilities that would produce a log file now have a `--nolog'
+  option to avoid printing a log file.
+
+  The tiled image compression convention (.fits.fz, created with `fpack')
+  files can now be used as input in the utilities.
+
   ImageCrop can now also crop a polygon from the input image. The polygon
   vertices can be given in the world or image coordinates. The simple
   `--polygon' option will keep the insides of the polygon while the
   `--outpolygon' will keep the outside of the polygon.
 
+  ImageCrop and ImageWarp can now read the WCS information of a FITS header
+  from a specific region with the `--hstartwcs' and `--hendwcs'. In some
+  older FITS images, when the WCS distortions were not as standardized as
+  now, there were cases which would confuse WCSLIB.
+
+  NoiseChisel can now save the grown clumps image instead of the original
+  clumps image in the output with the `--grownclumps' option.
+
+  Convolve can now do deconvolution with the `--makekernel' option.
+
+  MakeProfiles now has a `--setconsttonan' option which will fill the
+  contant profiles with a NaN (blank) value, not a number, allowing the
+  creations of elliptical masked regions for example.
+
+  Header can now import a keyword directly from a string with the `--asis'
+  option.
+
+  MakeCatalog can now output the geometric (average position independent of
+  pixel flux value) positions of the objects too.
+
+  MakeCatalog can now produce the object's elliptical parameters (for
+  example semi-major axis, semi-minor axis, and position angle). This can
+  also be done both in standard flux weighted and geometric methods too.
+
+  MakeCatalog now has a `--threshold' function to only use pixels above a
+  given threshold in each object or clump. This is useful to avoid diffuse
+  regions in calculations.
+
+  MakeCatalog now has a `--noriverbrightness' option. With this option it
+  is possible to calculate the clump flux without subtracting the river
+  pixels on its circumference.
+
+  The number of CPU threads is no longer a configuration option, it is now
+  determined at runtime for each program. Therefore it is now easily
+  possible to built Gnuastro on one system to use on another (commonly done
+  in the GNU/Linux package managers). Therefore ./configure no longer has a
+  `--with-numthreads' option.
+
+  Every commit in Gnuastro's history (after implementing this feature) can
+  now be given a unique version number. Since the version number is printed
+  in possible outputs, this feature can help reproducibility, even when the
+  an official/stable release isn't used.
+
+  The AUTHORS file is now automatically generated from the version
+  controlled history. Also all the authors that have contributed to
+  Gnuastro are included in the second (copyright) page of the PDF book.
+
+  All the bootstrapped directories are now moved with a new `bootstrapped'
+  directory in the top source directory. This significantly cleans up this
+  directory, allowing users to more easily find the hand-written Gnuastro
+  source files they like.
+
+  A `bug-gnuastro' Info page was created so users can easily go to that
+  page for information on how to submit bug reports. It is accessible on
+  the command line with the command `info bug-gnuastro'.
+
 ** Changes in behavior
 
+  MakeProfiles will now add a suffix to the individual images and put them
+  in the output directory if specified.
+
+  NoiseChisel and MakeCatalog now use the median mesh standard deviation to
+  define the over-all depth of the image. Previously they used the maximum
+  value (or the least depth).
+
+  NoiseChisel no longer outputs a sky subtracted image. This job can now be
+  done with the new Arithmetic utility.
+
+  NoiseChisel's `--segsnhistnbins' option was renamed to
+  `--clumpsnhistnbins'.
+
 ** Improvements
+
+  NoiseChisel's default quantiles were changed to 0.95 from 0.99. Since the
+  old value was too severe.
+
+  NoiseChisel's S/N thresholds are now found from the distribution of
+  pseudo-detections and clumps from the full image, not within each large
+  mesh. This was done to increase the accuracy of the S/N threshold. There
+  were commonly not enough points in large mesh sizes and this would add
+  scatter. With ImageCrop's polygon capabilities, it is now easily possible
+  to cut out the region that has uniform noise properties (depth and
+  correlated noise). Therefore the old `--checkdetectionsn' and
+  `checkclumpsn' options are no longer present.
+
+  When building from the version controlled source, the whole bootstrapping
+  process is done with one script. In the previous version, all the
+  separate operations should have been done by hand (as instructed in the
+  old manual).
+
+  All the build steps now report what was done and suggest the next
+  step. This feature can be disabled with the `--disable-guide-message' at
+  configure time.
