[AstroPy] APLpy 1.0 released

[Thomas Robitaille]

Hi everyone,

I am pleased to announce the release of APLpy 1.0! APLpy is a
Python module that makes it easy to interactively produce
publication-quality plots of astronomical images:

  http://aplpy.github.io

This version fixes a bug that occurred when using the recenter method
and RGB images, which could lead in some cases to the RGB image being
incorrectly re-centered. In addition, this version includes a new
method ``show_vectors`` that can be used to display for example
polarization maps (thanks to Martin Hardcastle for the contribution).

If you use pip, you should now be able to update using:

  pip install aplpy --upgrade

Please let me know if you have any issues with this release! The best
place to report any issues is via GitHub:

  https://github.com/aplpy/aplpy/issues

As a side note, it has been almost 6 years since the first release of
APLpy, and I felt that it is finally time to start using the 1.0
version number. The 1.x series of releases will be primarily concerned
with bug fixes.

Work on APLpy 2.0 has already started, and involves major internal
refactoring to make use of the WCSAxes package
(http://wcsaxes.readthedocs.org), and will also make use of new
features being introduced in Astropy 1.0 in order to simplify the
APLpy code. The aim will still be to maintain backward-compatibility
with existing scripts, but the output will no longer be guaranteed to
be strictly identical (because WCSAxes may choose default tick labels
differently for example, and deals correctly with the rotation of tick
marks).

Cheers,
Tom
