Envisage

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

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Also in this release, a number of outdated, incomplete or otherwise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- Remove outdated debugging fallback from the ``ExtensionPoint`` source.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- Remove unused and outdated ``tox.ini`` file.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)
- Usability improvements to ``etstool.py``. (145, 148)
