Added

* Improved widget handling, now use a dict to store components instead of parsing code.
Makes it possible to subscribe to events with expressions for the component.
* Cache behaves like dict, e.g. `cache['data'] = [1, 2, 3]`.
* Support Ant theme to customize all Ant components, added in the `App` class.
* Vertical option for slider. (204)
* Document run command.
* Document exceptions.

Breaking

* Removed cache `save` and `load` functions in favor of dict functionality.

Added

* Implemented `__getitem__` for the layout enabling for example: `app[1, 0:2] = widget`.
* Added "on_relayout" event for Plotly widgets.
* Serialize Pandas series objects and Pandas datetime objects.

Breaking

* `row_end` and `column_end` are now exclusive instead of inclusive.
* Simplified the `add` function in favor of the new getitem functionality,
which is easier to use and familiar to Python programmers.

Added

* Docstring examples of sizing components.
* More checks to ensure adding components works as expected.

Fixed

* Bug which incorrectly tracked which parts of the grid were occupied by widgets.

* Added a run command that simply combines build and serve together.
* Smarter build process that saves time on subsequent builds.
* Handle scheduled tasks when running with debug=True (185)
* Improve the Docker experience and docs.
* Always use the latest compiled bundle.

Breaking

* Instead of building the app by running `app.build()` you simply return the App instance.
See the quick start guide for an example.

Added

* Expose root `View` attributes as `App` attributes (175).
You can access `columns` and `rows` from the `App` instance like pre v0.5.

Accessible through `column_gap` and `row_gap` on `View` and `App` instances.
