The most significant change introduced in this minor release is the

=============

Pyface 7.1.0 introduces a few new features and fixes to deprecation warnings.
There are also internal cleanups to Qt signal connection logic that
should be invisible to users.

This release should be compatible with Traits 6.0+. Users are encouraged to
upgrade to Traits 6.1+ to stay current as future releases of Pyface will stop
supporting Traits 6.0.

Highlights of this release
--------------------------

* A new :mod:`data_view <pyface.data_view>` subpackage has been introduced to
support visualization of hierarchical and non-hierarchical tabular data. See
:ref:`data-view` section of the user manual for an introduction. Additional
examples are also added to the source distribution. Please note that as of
this release the API is provisional.

* A new :class:`Color <pyface.color.Color>` class and a corresponding
:class:`PyfaceColor <pyface.ui_traits.PyfaceColor>` trait type have been
introduced to support representing colors via a toolkit independent API. See
:ref:`ui-trait-types` section of the user manual for further details.

codebase. This release includes updating the WxPython backend to support
WxPython 4, an effort led by Rob McMullen's first cut at support, with
help from a number of other people. It also updates the code to use new
features of Traits 6, and just like Traits 6, this release drops support
for Python 2.

The release includes many bugfixes and a number of smaller incremental
enhancements. Other than the changed dependencies, Pyface 6 code should
largely work unmodified under Pyface 7.
