 - The `Label` widget is now right-aligned and has no width restriction: ([#1269](https://github.com/jupyter-widgets/ipywidgets/pull/1269))
 - Using function annotations to specify interact controls for a function is now deprecated and will be removed in a future version of ipywidgets. ([#1292](https://github.com/jupyter-widgets/ipywidgets/pull/1292))
-- Widgets are now displayed in the output area in the classic notebook and are treated as any other output. This allows the widgets to work more naturally with other cell output. To delete a widget, clear the output from the cell. ([#1274](https://github.com/jupyter-widgets/ipywidgets/pull/1274))
+- Widgets are now displayed in the output area in the classic notebook and are treated as any other output. This allows the widgets to work more naturally with other cell output. To delete a widget, clear the output from the cell. Output from functions triggered by a widget view is appended to the output area that contains the widget view. This means that printed text will be appended to the output, and calling `clear_output()` will delete the entire output, including the widget view. ([#1274](https://github.com/jupyter-widgets/ipywidgets/pull/1274), [#1353](https://github.com/jupyter-widgets/ipywidgets/pull/1353))
 - The Select widget now is a listbox instead of a dropdown, reverting back to the pre-6.0 behavior. ([#1238](https://github.com/jupyter-widgets/ipywidgets/pull/1238))
 - The Select and SelectMultiple widgets now have a `rows` attribute for the number of rows to display, consistent with the Textarea widget. The `layout.height` attribute overrides this to control the height of the widget. ([#1250](https://github.com/jupyter-widgets/ipywidgets/pull/1250))
 - Selection widgets (`Select`, `Dropdown`, etc.) now coerce their `options` argument to a tuple of `(label, value)` pairs. This makes it clearer the order in which the options will be presented. New `.value`, `.label`, and `.index` traits make it easier to observe or access the selected option.  ([#1262](https://github.com/jupyter-widgets/ipywidgets/pull/1262))

 - Removed the version validation check since it was causing too many false warnings about the widget javascript not being installed or the wrong version number. It is now up to the user to ensure that the ipywidgets and widgetsnbextension packages are compatible. ([#1219](https://github.com/jupyter-widgets/ipywidgets/pull/1219))
 - Play range is now inclusive (max value is max, instead of max-1), to be consistent with Sliders
+- A refactoring of the text, slider, slider range, and progress widgets in resulted in the `BoundedIntText` and `BoundedFloatText` losing their `step` attribute (which was previously ignored), and a number of these widgets changing their `_model_name` and/or `_view_name` attributes ([#1290](https://github.com/jupyter-widgets/ipywidgets/pull/1290))
+- The `Checkbox` description is now on the right of the checkbox and is clickable. The `Checkbox` widget has a new `indent` attribute (defaults to `True`) to line up nicely with controls that have descriptions. To make the checkbox align to the left, set `indent` to `False`. ([#1346](https://github.com/jupyter-widgets/ipywidgets/pull/1346))
+- The `Play` widget now has an optional repeat toggle button (visible by default). ([#1190](https://github.com/jupyter-widgets/ipywidgets/pull/1190))
+- A new Password widget, which behaves exactly like the Text widget, but hides the typed text: `Password()`. ([#1310](https://github.com/jupyter-widgets/ipywidgets/pull/1310))
+- A new SelectionRangeSlider widget for selecting ranges from ordered lists of objects. For example, this enables having a slider to select a date range. ([#1356](https://github.com/jupyter-widgets/ipywidgets/pull/1356))
+- The documentation theme is changed to the new standard Jupyter theme. ([#1363](https://github.com/jupyter-widgets/ipywidgets/pull/1363))

 - Custom serializers in Javascript are now synchronous, and should return a snapshot of the widget state. The default serializer makes a copy of JSONable objects. ([#1270](https://github.com/jupyter-widgets/ipywidgets/pull/1270))
 - Custom serializers in either Python or Javascript can now return a structure which contains binary buffers. If a binary buffer is in the serialized data structure, the message will be synced in binary, which is much more efficient. ([#1194](https://github.com/jupyter-widgets/ipywidgets/pull/1194))
 - A custom serializer is given the widget instance as its second argument, and a custom deserializer is given the widget manager as its second argument.
+- The widget manager `clear_state` method no longer has a `commlessOnly` argument. All models in the widget manager will be closed and cleared when `clear_state` is called. ([#1354](https://github.com/jupyter-widgets/ipywidgets/pull/1354))
