-This project’s release notes are curated from the Git history of its main
-branch. You can find them by looking at [the version of this file on the
-`release` branch][branch] or the [GitHub release history][gh-releases].
+- Fix build for traitlets >= 5.0 and in fact start requiring it.
+- Update minimum Python version to 3.7, as required by traitlets 5.
+- Require version 1.0 of the NPM package, so that we extrapolate clock
+  information from data provided by the JavaScript layer. This dramatically
+  reduces the level of traffic between the JS and Python layers.
+- Adopt Cranko for release automation, and revamp the continuous integration
+  infrastructure to implement such automation.

+
+# pywwt 0.9.0 (2020-08-29)
+
+- pywwt now obtains the WWT WebGL SDK code from web.wwtassets.org, rather than
+  a private copy hosted on the pywwt GitHub Pages instance.
+- Live notebook links now point to mybinder.org rather than the old private WWT
+  instance of BinderHub, because HTTPS support is now working!
+- Fix Jupyter server plumbing when operating in the JupyterHub single-user
+  environment.
+
+
+# pywwt 0.8.0 (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]
+
+
+# pywwt 0.7.0 (2019-09-20)
+
+- You can now save your WWT views as interactive figures to be used in journal
+  articles! (Actually, they're just standalone web pages, 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]
+
+
+# pywwt 0.6.1 (2019-06-10)
+
+- Fixed issues when calling `reset()`. [#212]
+- Fixed resizing issues in Jupyter Lab. [#216]
+- Fixed server URL when using Jupyter Lab. [#219]
+
+
+# pywwt 0.6.0 (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]
+
+
+# pywwt 0.5.3 (2019-01-16)
+
+- Exposed option to turn off large-scale SDSS data in 3D mode, improving
+  performance. [#176]
+- Make sure default altitude type is set correctly. [#176]
+
+
+# pywwt 0.5.2 (2019-01-08)
+
+- Added instructions for using Jupyter Lab. [#170]
+- Fixed `set_view('Mars')`. [#171]
+- Fixed issue with layers not appearing under certain circumstances. [#173]
+
+
+# pywwt 0.5.1 (2019-01-04)
+
+- Fixed a bug that caused layers to not immediately update when updating
+  data. [#167]
+- Fixed a bug that caused some columns to be pre-assigned to e.g. size_att
+  based on column name. [#167]
+
+
+# pywwt 0.5.0 (2019-01-04)
+
+- Fixed issues with zooming using trackpad/scroll wheel. [#166]
+- Added support for customizing the layer marker type (`marker_type`), the
+  option to specify whether the marker size is absolute or relative to the
+  screen (`marker_scale`), and the option to show points on the far side of
+  an object (`far_side_visible`). [#165]
+- Fixed a bug that caused issues with the distance/altitude of points when not
+  centered on the Earth. [#165]
+
+
+# pywwt 0.4.1 (2018-12-23)
+
+- Work around an issue with getting base URLs on e.g. mybinder.
+- Improvements to documentation. [#160, #164]
+
+
+# pywwt 0.4.0 (2018-12-20)
+
+- Added keyboard shortcuts for movement in-viewer. [#81]
+- Disable crosshairs by default. [#157]
+- Added `pause_time` and `play_time` for controlling time and make it
+  possible to control the rate of passage of time. [#146, #152]
+- Added support for displaying fields of view for common telescope. [#102]
+- Added `minor_orbits` and `stars` attributes to control the visibility
+  of minor orbits and stars in solar system mode. [#145]
+- Added support for showing tables of data using layers. [#122, #136, #139, #140, #143, #147, #150]
+- Added `load_fits_data` method for Qt and Jupyter clients. [#78]
+- Added support for non-sky modes (e.g. solar system mode). [#74, #83, #95, #98]
+- Added GUI controls for imagery layers using the `layer_controls` attribute. [#64]
+- Added support for exploring available imagery layers. [#71]
+- Added support for showing circle collections with annotations. [#54]
+- Switch to use OpenGL API. [#73]
+- Fixed compatibility with Jupyter Lab. [#63, #65]
+- Fixed compatibility with older versions of Qt. [#133]
+- Fixed compatibility with unicode strings for colors on Python 2. [#105]
+- Improved documentation. [#60, #70, #84, #101, #109]
+
+
+# pywwt 0.3.0 (2017-12-20)
+
+- Initial version with changelog
