Astropy v1.3 Released!

Dear colleagues,

We are very happy to announce the v1.3 release of the Astropy package, a core Python package for Astronomy:

Astropy is a community-driven Python package intended to contain much of the core functionality and common tools needed for astronomy and astrophysics.

New and improved major functionality in this release includes:

In addition, hundreds of smaller improvements and fixes have been made. An overview of the changes is provided at:

Instructions for installing Astropy are provided on our website, and extensive documentation can be found at:

If you make use of the Anaconda Python Distribution, you can update to Astropy v1.3 with:

    conda update astropy

Whereas if you usually use pip, you can do:

    pip install astropy --upgrade

Please report any issues, or request new features via our GitHub repository:

Over 210 developers have contributed code to Astropy so far, and you can find out more about the team behind Astropy here:

Astropy v1.0 (our long term support release) will continue to be supported with bug fixes until the v2.0 release in June 2017, so if you need to use Astropy in a very stable environment, you may want to consider staying on the v1.0.x set of releases (for which we are simultaneously releasing v1.0.11).

While we typically do not support non-LTS releases, we are also simultaneously releasing an Astropy v1.2.2, the last in that series. This update is primarily to include a leap second at the end of 2016 (but also contains other bug fixes).

If you use Astropy directly for your work, or as a dependency to another package, please remember to include the following acknowledgment at the end of papers:

This research made use of Astropy, a community-developed core Python package for Astronomy (Astropy Collaboration, 2013).

Please feel free to forward this announcement to anyone you think might be interested in this release.

We hope that you enjoy using Astropy as much as we enjoyed developing it!
