-## [2.7.1] - [UNRELEASED]
-### Updated
-- error message for `plotly.figure_factory.create_choropleth` is now helpful to Anaconda users who do not have the correct modules installed for the County Choropleth figure factory.
+## 3.0.0 - 2018-07-05
+
+This is a major version with many exciting updates. See the [Introducing plotly.py 3.0.0](https://medium.com/@plotlygraphs/introducing-plotly-py-3-0-0-7bb1333f69c6) post for more information.
+
+### Added
+- Full Jupyter ipywidgets integration with the new `graph_objs.FigureWidget` class
+- `FigureWidget` figures can be updated interactively using property assignment syntax
+- The full trace and layout API is generated from the plotly schema to provide a great experience for interactive use in the notebook
+- Support for setting array properties as numpy arrays. When numpy arrays are used, ipywidgets binary serialization protocol is used to avoid converting these to JSON strings.
+- Context manager API for animation. Run `help(go.Figure().batch_animate)` for the full doc string.
+- Perform automatic retries when communicating with plot.ly services. This introduces a new required dependency on the [retrying](https://pypi.org/project/retrying/) library.
+- Improved data validation covering the full API with clear, informative error messages. This means that incorrect properties and/or values now always raise a `ValueError` with a description of the error, the invalid property, and the available properties on the level that it was placed in the graph object. Eg. `go.Scatter(foo=123)` raises a validation error. See https://plot.ly/python/reference/ for a reference to all valid properties and values in the Python API.
+- Error message for `plotly.figure_factory.create_choropleth` is now helpful to Anaconda users who do not have the correct modules installed for the County Choropleth figure factory.

+## Installation of plotly.py Version 3
+To install plotly.py and enable Jupyter or Jupyter Lab support, run:
+```
+pip install "plotly>=3.0"
+pip install "notebook>=5.3" "ipywidgets>=7.2"  # only necessary for Jupyter Notebook environments
+```
+
+If you're using older versions of `notebook` or `ipywidgets` you may need to manually activate the widget extensions (this should not be needed for `notebook>=5.3` and `ipywidgets>=7.2`)
+
+```
+jupyter nbextension enable --py widgetsnbextension --sys-prefix
+jupyter nbextension enable --py plotlywidget --sys-prefix
+```
+
+In addition, to add JupyterLab support run the following commands
+
+```
+pip install jupyterlab
+export NODE_OPTIONS=--max-old-space-size=4096
+jupyter labextension install @jupyter-widgets/jupyterlab-manager # install the Jupyter widgets extension
+jupyter labextension install plotlywidget
+```
