v0.8.0 (2020-04-03)

• Improve performance when changing size parameters for tabular layers. In these cases, the performance is e.g. more than 1000x better for a 50,000 row dataset. [#224]
• Improve performance when changing colormap parameters for tabular layers, for a subset of colormaps. In these cases, the performance is e.g. more than 1000x better for a 50,000 row dataset. [#223]
• Added a cmap parameter on image layers to control the colormap. [#244]
• Incorporate time series behavior for data layers; add method that returns current time in the viewer. [#187]
• Drop support for Python 2.7 and now require at least Python 3.6. [#259]
• Fix compatibility with Jupyter 2.0. [#260]

v0.7.0 (2019-09-20)

• You can now save your WWT views as interactive figures to be used in journal articles! (Actually, they're just standalone webpages, so they can be used anywhere you've got a web server.) This feature is new so it will still have some rough edges — keep your eyes open for improvements. And the docs haven't been written yet :-( [#215, #227]
• Relatedly, there is new first-draft support for interactive controls for image layers through the image.controls meta-property. This will also evolve over the next few releases. [#217]
• Initial support for data layers with Cartesian (XYZ) rather than spherical (lat, lon, alt) coordinates. [#190]
• Fix compatibility with the JupyterLab 1.0.x series. [#216, #219, #221]
• Expose all available imagery layers. [#220]
• Validate coordinate frame names used with tabular data layers. [#195]
• Fix the widget reset method . [#212]
• Various improvements to CI infrastructure, docs, landing pages, etc. [#218, #225, #228, #229, #230]

v0.6.0 (2019-05-29)

• Implement support for color-coding and scaling points in layers according to table attributes. [#183]
• Removed load_fits_data and added layers.add_image_layer instead, which provides control over the image stretch, and renamed layers.add_data_layer to layers.add_table_layer. [#188, #201]
• Added support for drag and drop events in Qt widget. [#202]
• Added support for get_center for the Jupyter widget, and add a new get_fov method to get the current field of view. [#206]
• Fixed compatibility with notebook>=5.7.6 which requires mime types for served files to be correct. [#192, #208]
• Fixed display of table layers on Windows. [#207]
