  the PreferencesPane before changes were approved. (#583)
• Add a name attribute to the EventManagerPlugin. (#571)

Build

• Update copyright header end years for 2024, 2025. (#572, #589)

  actions to their latest versions. (#573, #575, #576, #577, #579, #581, #588)
• Remove Slack notifications, which were using an outdated
  and unmaintained GitHub Action. (#580)
• Require apptools 5.3 or later and Python 3.8 or later. (#584)

Envisage 7.0.3

This is a bugfix release that fixes the automated documentation build
for releases.

Fixes

• Fix the GitHub Actions workflow for automated documentation updates
  on releases. (#568)

Envisage 7.0.2

This is a bugfix release that fixes some test interaction issues and
automates the documentation build.

Fixes

• Fix test-ordering issues with egg-based tests that modify pkg_resources
  global state. (#564)

Documentation

• Reorganise the gh-pages documentation. The main gh-pages page
  (https://docs.enthought.com/envisage) now matches the contents of the GitHub
  main branch, while subdirectories (e.g.,
  https://docs.enthought.com/envisage/7.0) provide documentation for released
  versions. A 'latest' symlink is in place, so
  https://docs.enthought.com/envisage/latest will bring up the documentation
  for the latest release. (#565)

Build

• Add GitHub Actions workflows to automate documentation updates. The main
  documentation is updated on every push to main, while the release
  documentation is updated on each GitHub release creation. (#565)

Envisage 7.0.1

This is a bugfix release whose main purpose is to fix the Read the Docs
build for the Envisage documentation.

Fixes

• Fix the documentation build for Read the Docs. (#560)
• Fix example code that was importing Font and Color from Traits
  instead of TraitsUI. (#558)

Envisage 7.0.0

This is a major release aimed at modernization and cleanup of some out-of-date
code. In particular, this release removes the IPython-related plugins, and
drops support for Python 3.6.

Thanks to:

• Mark Dickinson
• Chengyu Liu
• Corran Webster

Features

• There's a new unbind_extension_point function that reverses the effects
  of bind_extension_point. This can be useful for clean teardown. (#546)
• All id string constants that were previously available from envisage.ids
  are now also exported in envisage.api. Users are encouraged to import
  everything they need from envisage.api, and to open an issue if anything
  they need is not exported in envisage.api. (#508)

Changes

• When exiting a TasksApplication, the plugins are now stopped after
  exiting the event loop. Previously they were stopped while the event loop was
  still running, causing some lifecycle issues. (#524)
• The extension_registry argument to bind_extension_point is no
  longer optional, and ExtensionPointBinding will no longer look for
  an extension registry on the ExtensionPoint class. (#545)
• Operations that used to raise SystemError now raise something more
  appropriate. In particular, the PluginManager.start_plugin and
  PluginManager.stop_plugin methods now raise ValueError rather
  than SystemError when given an invalid plugin id. (#529)
• envisage.__version__ is no longer defined. If you need the Envisage
  version at runtime, use importlib.metadata to retrieve it. (#513)
• Python 3.6 is no longer supported. All current versions of Python (3.7
  through 3.11) are supported. (#513)

Fixes

• The repr of a Plugin instance now correctly uses the name of the
  plugin class. (#535)

Deprecations

• The EggPluginManager, EggBasketPluginManager and
  PackagePluginManager are deprecated, and will be removed in Envisage 8.0.
  (#540)
• The include and exclude traits on the PluginManager are
  deprecated, and will be removed in Envisage 8.0. (#544)

Removals

• Plugins and machinery related to IPython have been removed. Specifically,
  the IPythonKernelPlugin and IPythonKernelUIPlugin plugins have been
  removed, along with supporting classes InternalIPKernel and
  IPKernelApp. (#496)
• The ExtensionPoint.bind method has been removed. (#545)
• The previously deprecated safeweakref.ref class has been removed. (#522)
• Some legacy unmaintained examples have been removed. (#557)

Documentation

• The changelog is now included in the built documentation. (#550)

Tests

• Old-style namespace packages used for testing have been replaced with
  normal non-namespace packages. This fixes some warnings from the latest
  setuptools. (#543)
• The test suite now runs cleanly under pytest. (#539)
• Tests that are skipped due to a PySide6 problem should now be run
  if the version of PySide6 is recent enough. (#554)

Build

• Package configuration now uses pyproject.toml in place of the old
  setup.py-based configuration. (#513)
• Optional dependencies are no longer declared. (#513)
• A new style-checking workflow has been added that runs black, isort
  and flake8 over the codebase, and new code is expected to comply with
  black and isort configurations. (#549)
• A new documentation-build workflow has been added. The built documentation
  is uploaded as an artifact. (#551)

Envisage 6.1.1

This is a bugfix release that fixes an incompatibility between the workbench code and the latest Traits version, among other minor fixes.

Thanks to:

• Mark Dickinson
• Prabhu Ramachandran
• Scott Talbert

Fixes

• A trait validation error in the Workbench DefaultActionSet has been fixed. This fixes a compatibility issue with Traits 6.4. (#485)
• Initialization of application directories now correctly respects the value of self.state_location. (#490)
• In the test suite, egg generation now uses sys.executable to ensure it picks up the correct Python executable. (#499)

Other changes

• The version of PySide6 used in test workflows has been restricted. (#487)
• The EDM version used in test workflow has been updated. (#484)
• Various fixes have been made to the GitHub Actions workflows, for compatibility with the newest runners. (#491, #494)
• Copyright headers have been updated for 2023. (#493)

Envisage 6.1.0

This is a minor feature release whose main focus is on compatibility with
Python 3.8 and PySide 6. It includes a collection of other cleanups and minor
fixes.

In this release, there are some changes in the way that the Envisage
Application interacts with ETSConfig. You should double check that
the locations of user data, preferences and application home directories are
the ones that you expect after upgrading.

Please note that the IPython-related portions of Envisage are currently not
compatible with the latest versions of ipykernel and IPython available from
PyPI. This has been made explicit in this release in the form of version
restrictions on those packages in the envisage[ipython] install target.

Thanks to:

• Aaron Ayres
• Mark Dickinson
• Sai Rahul Poruri
• Corran Webster

Changes

• The Application.user_data directory no longer includes the id
  of the application, but instead matches the ETSConfig.user_data. (#467)
• The Envisage Application will no longer try to change the
  ETSConfig.application_home attribute. (#467)
• The PackageResourceProtocol now uses importlib.resources instead
  of pkg_resources. (#466)
• The IPython-related features of Envisage require ipykernel version < 6 and
  IPython version < 8. (#449)

Fixes

• Fix EggPluginManager to use current pkg_resources.working_set. (#444)

Refactoring and maintenance

  (#470)
• Fix an EggBasketPluginManager test that only passed due to test
  interactions. (#443)
• Some pickles used in testing have been regenerated in order to work
  correctly with more recent versions of Traits. (#472)
• Fix poorly specified action and menu groups in tests. (#468)
• Fix test hangs with PySide2 / macOS 11. (#454)

certain cases. We recommend all users of Envisage to upgrade to this bugfix
version.

Fixes

Envisage 6.0.0

This major release focuses on speeding up Envisage applications. We achieved this speedup by removing unused functionality in the package. Specifically, we removed the @contributes_to decorator and the code needed to handle methods decorated with the above decorator.

Additionally, with this release, parts of Envisage start using the new Traits observation framework instead of the old Traits on_trait_change. So, Envisage now depends on Traits version >= 6.2.

Features

• Support observe(name:items) for Extension Points. (#354)

Changes

• Replace Either trait type with Union. (#405)
• Rewrite *_changed static trait handlers to use observe. (#401)
• Replace depends_on in Property traits with observe. (#400)
• Change default pickle protocol to be compatible with Python >= 3.4. (#390)

Removals

• Remove contributes_to decorator and supporting code. (#402)
• Remove unnecessary return statements throughout the codebase. (#393)

Build

• Ensure that the cron job installs all necessary dependencies. (#383)

Envisage 5.0.0

This is a major release mainly relating to code modernization. In this
release, support for Python versions <3.6 have been dropped. The
class_load_hooks and single_project modules have been removed. Additionally,
there were various fixes to bugs, examples, tests, and documentation. Demo
examples are also distributed as package data such that they are visible via
the "etsdemo" GUI application (to be installed separately).
