GNU Astronomy Utilities (Gnuastro) is an official GNU package consisting of various programs and library functions for the manipulation and analysis of astronomical data. All the programs share the same basic command-line user interface for the comfort of both the users and developers. Gnuastro is written to comply fully with the GNU coding standards so it integrates finely with the GNU/Linux operating system. This also enables astronomers to expect a fully familiar experience in the source code, building, installing and command-line user interaction that they have seen in all the other GNU software that they use.

** New publications

al. on Gnuastro's zero point measurement script for calibration of
astronomical images ('astscript-zeropoint').

Akhlaghi on Gnuastro's script to visualize the full dynamic range of
astronomical images ('astscript-color-faint-gray').

et al. on Gnuastro's script to measure the radial profile of a given
source ('astscript-radial-profile').
** New features
*** New program
- 'astscript-color-faint-gray': a new installed script to maximize the
visualization of the contents within your astronomical images. It does
this by showing the brighter parts of the image as color, intermediate
regions as black and the noisy/faint regions as gray/white.
*** All programs
- The following options are now available in all programs to allow
customization of which metadata is printed in the 0-th HDU of the FITS
output of all Gnuastro programs. Also see the "Changed features" list
for an important change in this regard to all Gnuastro output FITS
files.
--outfitsnoconfig: do not print any metadata in the 0-th HDU (including
the used options and their values, the date, the versions and git
commit of running directory).
--outfitsnodate: do not write the 'DATE' keyword.
--outfitsnoversions: do not write the versions of Gnuastro and
mandatory dependencies.
--outfitsnocommit: do not write the Git commit.
*** Arithmetic
--arguments: takes the name of plain-text file that contains the list of
arguments to the program. This option is critical if you have very long
(thousands) of operands and operators (which happen in large pipelines
where the arguments are constructed automatically). Without this
option, the shell is going to abort with an "Argu
