upcoming Traits 6.0.0 release.

This is a minor feature release with a small handful of fixes, and a single
new feature to make the IPythonKernelPlugin easier to use for applications.

• Add an option to allow the InternalIPKernel to initialise its kernel at
  kernel creation time. At some point in the future, this will become the
  default behaviour. (#227)

Fixes

  originally. (#232)

Tests

• Remove a print call from a unit test. (#240)
• Add unit tests for the envisage.ui.single_project adapters. (#235)
• Add unit tests to check that InternalIPKernel doesn't affect
  sys.path. (#233)
• Fix the test suite not to write to the user's ~/.ipython directory.
  (#231)
• Fix the test suite not to write to the user's ~/.enthought directory.
  (#230)
• Remove an unused import and a useless tearDown method in the
  IPythonKernel tests. (#223)
• Fix DeprecationWarnings from uses of long-deprecated TestCase
  methods. (#222)
• Add test eggs for Python 3.8. (#214)

Build

• Rename changelog extension from .txt to .rst. (#238)
• Update EDM version used in Travis CI and Appveyor. (#236)
• Add mock to test dependencies on Python 2. (#229)
• Fix status badges in README. (#216)

Envisage version 4.8.0

Envisage 4.8.0

Released: 2019-09-13

The main focus of this feature release is the IPythonKernelPlugin, which
has been updated to work with the latest IPython-related packages from PyPI,
and is now much more careful about releasing resources allocated.

Also in this release, a number of outdated, incomplete or otherwise
nonfunctional pieces of code were removed.

Features

• Improved repr for ExtensionPoint objects. (#142)

Changes

• Drop support for Python versions older than 2.7 and Python 3 versions older
  than Python 3.5. (#139)
• The IPythonKernelPlugin now releases all allocated resources (threads,
  file descriptors, etc.) and undoes global state changes at plugin stop
  time. (#188)
• Suppress the Ctrl-C message printed by the IPython kernel at start time.
  (#182)
• Add license headers to all files, and make license header statements
  consistent. (#192)

Fixes

• Use a fixed pickle protocol when saving task layout state, to avoid
  cross-Python-version difficulties. (#179)
• Fix deprecation warnings from use of Logger.warn. (#178)
• Fix some Python 3 syntax errors in example scripts. (#171)

Removals

• Remove the unsupported and incomplete UpdateCheckerPlugin. (#199)
• Remove the plugin.debug empty submodule. (#195)
• Remove the old IPythonShell plugin, which was based on pre-IPython 1.0.
  (#173)
• Remove the non-functional RefreshCodePlugin. (#202)
• Remove project_runnable, which was never functional. (#169)
• Remove outdated debugging fallback from the ExtensionPoint source. (#167)
• Remove FBIPlugin. (#166)
• Remove the remote_editor plugins. (#137)

Documentation

• Add docstrings for tasks plugin extension points. (#181)
• Fix incorrect documentation for always_use_default_layout. (#177)
• Spell "Pyface" correctly. (#176)
• NumPyDoc style fixes. (#168)
• Add API documentation, with corresponding build infrastructure. (#165)
• Fix invalid syntax in Tetris example. (#158)
• Use the Enthought Sphinx Theme for documentation. (#157)

Tests

• Remove dependency on the nose package, and rename test modules. All
  tests can now be discovered and run using unittest. (#200, #194)

Build

• Revise version-handling mechanisms and other minor details
  in setup.py script. (#197, #190)
• Remove unused and outdated tox.ini file. (#201)
• Update etstool.py to work with a non-EDM bootstrap environment on
  Windows. (#203)
• Test against other ETS packages from source, using Travis CI cron jobs.
  (#162)
• Fix deprecated pieces in Travis CI configuration. (#160, #159)
• Update EDM version used, and clean up and simplify Travis CI and
  Appveyor configurations. (#152)
