3.4:
This release removes support for Python 2.5, as well as Python 3.0 - 3.2.
Supported Python versions are now Python 2.6, 2.7, and 3.3+. This
release incorporates new features and bug fixes made in the
``astropy.io.fits`` module in Astropy, which is originally based on PyFITS
and supersedes the stand-alone PyFITS module.
This will likely be the last stand-alone release of PyFITS that does not
depend on Astropy. There are a few reasons for this:
1) Development resources for PyFITS are limited, and better focused on
newer projects.
2) Astropy incorporates all features of PyFITS, and has many new features
from which future development of the FITS reader/writer can benefit, such
as a better table interface, units, and datetime types. Since the most
beneficial future development in ``astropy.io.fits`` depends on other
parts of Astropy there is less motivation to maintain an independent FITS
module.
This release contains most changes to the ``astropy.io.fits`` module that
have been made since the last release of PyFITS (v3.3), except for changes
that depend explicitly on other parts of Astropy. This brings PyFITS mostly
to parity with the version of ``astropy.io.fits`` that will be in Astropy
v1.1.2.
