Dear colleagues,

We are very happy to announce the v0.5 and v0.4.1 releases of the Photutils
package.  Photutils is an astropy coordinated package to perform photometry
(both aperture and PSF-fitting), ePSF building, PSF matching, source
detection, image segmentation, background estimation, and elliptical
isophote analysis.

The v0.5 release supports Python 3.5+.  New major functionality includes an
effective PSF builder following the prescription of Anderson & King (2000;
PASP 112, 1360):

The v0.4.1 release is a bugfix-only release for those still using Python
2.7.  In particular, it provides bugfixes to support Python 2.7 with
scikit-image 0.14+ and numpy 1.14+.

Many smaller improvements and fixes have also been made.  Please see the
changelogs of both versions for details.

The releases are available on PyPI and on the usual conda channels
(astropy, conda-forge, and astroconda).  Python 3.7 builds are not yet
available on the astropy and conda-forge channels, but in the meantime they
are available on PyPI and the astronconda channel.

If you use Photutils, please cite the package via its Zenodo record:
