- Update to version 5.1.1
* 5.1.1 fixes compatibility issues with Python 3.10 (rc2).
- Release 5.1.0
* Traitlets 5.1 brings a couple of updates and changes to
traitlets, and is recommended for all users. What follow is a
non-exhaustive list of changes:
* Removal of the ``ipython_genutils`` dependency, this should
remove any direct and indirect reliance on ``nose`` and prepare
traitlets 5.1 for Python 3.10 and above compatibility, some
test suite changes also accommodate Python 3.10 changes. If you
package traitlets downstream, make sure to remove this
dependency.
* Removal of ``ipython_genutils`` may have change the default
encoding detected for the command line argument parsing when
not utf-8. We expect this to affect a small portion of older
windows version. If you encounter issue let us know.
* Stop recommendation of ``CUnicode`` in some circumstances as
it's deprecated.
* Our test suite is now using GitHub action instead of travis CI.
If you are packaging downstream using the git repository, you
may have to exclude the ``.github`` folder now, and can remove
exclusion of
* It fixes a parsing issue for list of one single element on the
CLI.
* We reserve the right to remove official support for Python 3.7
in subsequent minor revisions.
- Releases 5.0.2 to 5.0.5
* Support deprecated literals for sets, tuples on the
command-line: ``nbconvert
--TagRemovePreprocessor.remove_cell_tags=' *"tag"}'``
* Fix ``from_string_list`` for Tuples in general
* Fix support for ``List(default_value=None, allow_none=True)``
and other Container traits
* Fix help output for nested aliases and tuple traits
* Support deprecated use of byte-literals for bytes on the
command-line: ``ipython kernel --Session.key="b'abc'"``. The
`b` prefix is no longer needed in traitlets 5.0, but is
supported for backward-compatibility
* Improve output of configuration errors, especially when help
output would make it hard to find the helpful error message
* Fix regression in handling `--opt=None` on the CLI for configurable traits
with `allow_none=True`
* Fix casting bytes to unicode
- Traitlets 5.0
* Traitlets 5.0 is a new version of traitlets that accumulate
changes over a period of more close to four years; A number of
internal refactoring made the internal code structure cleaner
and simpler, and greatly improved the diagnostic error messages
as well has help and documentation generation.
* We expect no code change needed for any consumer of the Python
API (ipywidgets, and alike), though CLI argument parsing have
seen a complete rewrite, so if you have an application that
does use the parsing logic of traitlets you may see changes in
behavior, and now have access to more features.
* Major changes are:
- Removal of Python 2 support,
- Removal of Python 3.0-3.6 support
- we now follow NEP 29, and are thus Python 3.7+ only.
- remove ``six`` as a dependency
- remove ``funcsig`` as a dependency.
- Fix build without python2
- Update to version 4.3.3
* Adds Application.loaded_config_files property for accessing
config files that have been loaded and makes the property
idempotent on multiple loads.
- Add missing python-six BuildRequires
- Add missing python-six Requires
- Implement single-spec version.
- Update to 4.3.2
* using :meth:`_traitname_default()` without the ``@default``
decorator is no longer deprecated.
* Passing ``config=True`` in traitlets constructors is no longer
deprecated.
- Update to 4.3.1
* Compatibility fix for Python 3.6a1
* Fix bug in Application.classes getting extra entries when
multiple Applications are instantiated in the same process.
- Update to 4.3.0
* Improve the generated config file output.
* Allow TRAITLETS_APPLICATION_RAISE_CONFIG_FILE_ERROR env to
override :attr:`Application.raise_config_file_errors`,
so that config file errors can result in exiting immediately.
* Avoid using root logger. If no application logger is registered,
the ``'traitlets'`` logger will be used instead of the root
logger.
* Change/Validation arguments are now Bunch objects, allowing
attribute-access, in addition to dictionary access.
* Reduce number of common deprecation messages in certain cases.
* Ensure command-line options always have higher priority than
config files.
* Add bounds on numeric traits.
* Improves various error messages.
- Update to 4.2.2
* Partially revert a change in 4.1 that prevented IPython's
command-line options from taking priority over config files.
- Update to 4.2.1
* Demotes warning about unused arguments in ``HasTraits.__init__``
introduced in 4.2.0 to DeprecationWarning.
- Update to 4.2.0
* :class:`JSONFileConfigLoader` can be used as a context manager
for updating configuration.
* If a value in config does not map onto a configurable trait,
a message is displayed that the value will have no effect.
* Unused arguments are passed to ``super()`` in
``HasTraits.__init__``, improving support for multiple
inheritance.
* Various bugfixes and improvements in the new API introduced
in 4.1.
* Application subclasses may specify
``raise_config_file_errors = True``
to exit on failure to load config files,
instead of the default of logging the failures.
- Update to 4.1
* Decorators are used, rather than magic method names, for
registering trait-related methods. See :doc:`using_traitlets`
and :doc:`migration` for more info.
* Deprecate ``Trait(config=True)`` in favor of
``Trait().tag(config=True)``. In general, metadata is added
via ``tag`` instead of the constructor.
* Trait attributes initialized with ``read_only=True`` can only
be set with the ``set_trait`` method.
Attempts to directly modify a read-only trait attribute raises
a ``TraitError``.
* The directional link now takes an optional `transform`
attribute allowing the modification of the value.
* Various fixes and improvements to config-file generation
(fixed ordering, Undefined showing up, etc.)
* Warn on unrecognized traits that aren't configurable, to avoid
silently ignoring mistyped config.
