Astropy is a community-driven Python package intended to contain much of the core functionality and common tools needed for astronomy and astrophysics. It is part of the Astropy Project, which aims to foster an ecosystem of interoperable astronomy packages for Python.
New and improved major functionality in this release includes:
* New Sub-package for Time Series * New SI/CODATA 2018 Constants * Additions and changes to Ecliptic Transformations * Table performance improvements and change in metadata handling * Table I/O integration of pandas I/O functions for ASCII tables * Improved help on Table read() and write() methods
In addition, hundreds of smaller improvements and fixes have been made. An overview of the changes is provided at:
As a reminder, Astropy v2.0 (our long term support release) will continue to be supported with bug fixes (but no new features) until the end of 2019, so if you need to use Astropy in a very stable environment, you may want to consider staying on the v2.0.x set of releases (for which we have recently released v2.0.13).
If you use Astropy directly for your work, or as a dependency to another package, please remember to acknowledgment it by citing the appropriate Astropy paper. For the most up-to-date suggestions, see the acknowledgement page, but as of this release the recommendation is:
