+Announcement: GraSPy 0.0.3
+==========================
+
+We're happy to announce the release of GraSPy 0.0.3! GraSPy is a Python package for 
+understanding the properties of random graphs that arise from modern datasets, such as
+social networks and brain networks.
+
+For more information, please visit our `website <http://graspy.neurodata.io/>`_
+and our `tutorials <https://graspy.neurodata.io/tutorial.html>`_.
+
+
+Highlights
+----------
+This release is the result of over 2 months of work with over 16 pull requests by 
+4 contributors. Highlights include:
+
+- Optimization over covariance structures when using ``GaussianCluster``
+- Standardized sorting for visualizing graphs when using ``heatmap`` or ``gridplot``
+- Graph model classes for fitting several random graph models to input datasets
+- Improved customization for ``heatmaps`` and ``gridplots``
+
+
+Improvements
+------------
+- Added badges to Github for arxiv paper and number of downloads
+- Remove author headers for individual source files 
+- Fix bugs in documentation
+- Bug fix for calculating intersection of largest connected components between graphs
+- Pre-defined axes can be passed to ``heatmap`` for making subplot figures
+- Colormap objects and color bounds can be passed to ``heatmap`` directly
+
+API Changes
+-----------
+- ``SemiparametricTest`` was renamed to ``LatentPositionTest``
+- ``NonparametricTest`` was renamed to ``LatentDistributionTest``
+- ``heatmap`` and ``gridplot`` accept ``hier_label_fontsize`` and ``title_pad`` kwargs
+
+Deprecations
+------------
+- The notebooks folder was removed from ``GraSPy``
+- ``SemiparametricTest`` and ``NonparametricTest`` renamed (see above)
