Item posted by Mohammad Akhlaghi <makhlaghi> on Mon 03 Oct 2016 01:27:11 PM UTC.

I am pleased to announce the second release of GNU Astronomy Utilities (Gnuastro).

Gnuastro is a collection of programs and library functions for astronomical data manipulation and analysis. The programs are run directory on the command-line, enabling easy and efficient operationS (combined with other installed programs) in shell scripts or Makefiles. The libraries are also usable in C and C++ programs.

The main changes in this version can be seen in the NEWS file which is also distributed with this announcement in footnote 1 (below). The most notable new features are:

Here are the compressed sources:   (4.0MB)   (2.7MB)

Here are the GPG detached signatures, see footnote 2 (below):

Use a mirror for higher download bandwidth:
(Note that mirrors will need some time to synchronize with the main server)

Here are the MD5 and SHA1 checksums of the tarballs.

Bug fixes

New programs or headers

Changes in behavior

Footnote 2

Use a .sig file to verify that the corresponding file (without the .sig suffix) is intact.  First, be sure to download both the .sig file and the corresponding tarball.  Then, run a command like this (similar for `tar.lz' files):

gpg --verify gnuastro-0.2.tar.gz.sig

If that command fails because you don't have the required public key,
then run this command to import it:

gpg --keyserver --recv-keys 16A8A4B2AEC42AFF

and rerun the 'gpg --verify' command.
