- Update to 2.0.0
* Parameter slot values are now all inherited correctly across
a hierarchy of Parameterized classes.
* There is now a ListProxy wrapper around Selector.objects (with
forward and backward compatibility) to easily update objects
and watch objects updates.
* Parameterized classes and instances now have a rich HTML
representation that is displayed automatically in
a Jupyter/IPython notebook.
* Parameters have all gained the allow_refs and nested_refs
attributes, bringing an exceptionally useful feature that was
available in Panel since version 1.2 to Param.
* Experimental new rx reactive expressions.
* You can now use .param.update as a context manager for applying
temporary updates.
* For speed, only generate the Parameter docstring in an IPython context.
* Support for deserialization of file types into Array and DataFrame.
* Integer now accepts numpy.integer values.
* Range now does stricter validation of the slot values.
* Path now has check_exists attribute, leading it to raise an error
if path is not found on parameter instantiation.
* Add top-level __all__ and move Parameter classes to parameters.py.
* Now compatible with Python 3.8+
* Other changes, take a look at the upstream changelog.
