ANN: poliastro 0.6 released

[Juan Luis Cano]

Hi all,

I am very pleased to announce poliastro 0.6.0, a MIT licensed, pure 
Python library for studying Orbital Mechanics and Astrodynamics problems!

This is a new major release, focused on refactoring some internal core 
parts and improving the propagation functionality. Among the new 
features are:

* Support for Python 3.6.
* Allow propagation functions to receive a callback
* New Orbit objects that supersede the State API.

See the changelog for a more complete list of changes:

http://poliastro.readthedocs.io/en/v0.6.0/changelog.html#new-in-poliastro-0-6-0

You can install poliastro using either pip or conda:

    $ pip install poliastro

    $ conda install poliastro --channel conda-forge

And cite it using this DOI:

https://doi.org/10.5281/zenodo.290596

If you want to see an overview of poliastro capabilities, check out the 
gallery of Jupyter notebooks where we list some specific applications 
and interesting problems analyzed with this library:

This release is probably the last one I'm going to make as an "almost 
aerospace engineer", so wish me luck for my MSc final project :) You can

poliastro is an open source collection of Python subroutines for solving 
problems in Astrodynamics and Orbital Mechanics. It combines cutting 
edge technologies like Python JIT compiling (using numba) with young, 
well developed astronomy packages (like astropy and jplephem) to provide 
a user friendly API for solving Astrodynamics problems. It is therefore 
an experiment to mix the best Python open source practices with my love 
for Orbital Mechanics.

The project is still a work in progress and the API is subject to 
change. Contributions, bug reports, suggestions and advice are more than 
welcome! If you are willing to help, please join our mailing list on
