```
- 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))

- ToggleButtons have a new `.style.button_width` attribute to set the CSS width of the buttons. Set this to `'initial'` to have buttons that individually size to the content width. ([#1257](https://github.com/jupyter-widgets/ipywidgets/pull/1257))
- Selection container widgets (`Accordion`, `Tabs`) can have their `.selected_index` set to `None` to deselect all items. ([#1495](https://github.com/jupyter-widgets/ipywidgets/pull/1495))
- The `IntRangeSlider` widget now has a `.readout_format` trait to control the formatting of the readout. ([#1446](https://github.com/jupyter-widgets/ipywidgets/pull/1446))
- The `Text`, `Textarea`, `IntText`, `BoundedIntText`, `FloatText`, and `BoundedFloatText` widgets all gained a `continuous_update` attribute (defaults to `True` for `Text` and `TextArea`, and `False` for the others). ([#1545](https://github.com/jupyter-widgets/ipywidgets/pull/1545))
- The `IntText`, `BoundedIntText`, `FloatText`, and `BoundedFloatText` widgets are now rendered as HTML number inputs, and have a `step` attribute that controls the resolution. ([#1545](https://github.com/jupyter-widgets/ipywidgets/pull/1545))
- The `Text.on_submit` callback is deprecated; instead, set `continuous_update` to `False` and observe the `value` attribute: `mywidget.observe(callback, 'value')`. The `Textarea.scroll_to_bottom` method was removed. ([#1545](https://github.com/jupyter-widgets/ipywidgets/pull/1545))
