This is the second release of python-gegl: it became really rich in features, and GEGL can be used through it as a functional image manipulation library that will work out of the box.
It works for both python 2 (2.7) and python 3 (>= 3.2) - and it is out of the box in Linux distributions which have at least gegl 0.2 built with gobject introspection enabled (tested on fedora 20, x64). It might work in other platforms given gobject introspection and gegl are properly configured..
Although marked as "beta" the working semantics will remain the same, and what already works won't be changed. Since the real functionality is provided by the underlying GEGL library, which has been the engine in GIMP image operations for several years already, it is quite safe to be used in a production environment. Some of the missing features for this package can be seen in the TODO.txt file.
(NB. the file bellow is for the archives listed in PYPI as v. 0.2.1 - the only difference for the
intended original 0.2 release being a fix in the setup.py file)
