Pyface 7.0.0

Pyface 7.0.0 is a major release which focuses on modernization of the
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.

Pyface 6.1.0

This release introduces a number of new features and bugfixes. The most prominent of these is a set of Application classes designed to smooth the transition between Tasks applications which use only Pyface, and those that take advantage of the Envisage plug-in framework. Developers can now write a Pyface TasksApplication and then easily transition to an Envisage TasksApplication as the needs of their codebase grows. This feature has been a few years in development, and thanks is due to Jonathan Rocher for helping push this through to completion.

This release also includes a complete re-write of the Pyface timer code to make it easier to use and to provide a consistent and more Pythonic API shared by the different back-ends. A backwards compatible API is still available, but users of the Pyface timer code are encouraged to update to the new API.

ToolBars can now embed simple widgets, such as text fields, integer spinners, and comboboxes, as well as simple TraitsUI views. This is provided via a new "widget" style for Actions as well as the utility subclasses FieldAction and TraitsUIWidgetAction.

Although not visible to most users of Pyface, this release removes the use of 2to3 and now uses a unified codebase supported by the six library. Thanks to Rahul Poruri for performing this transformation. This should help significantly with ongoing development work in the coming years.

We also include experimental support for PySide2 (also called "Qt for Python"). We are running CI tests using the 5.11 release of PySide2 with success on OS X and Linux for Python 3, but are experiencing failures with the 5.12 release.

Finally, this release includes a number of bugfixes and minor enhancements which should improve the reliability and utility of the codebase.
