- Fix for delete_row() in GridBox widgets
- Fix for TextEntry widget in pg backend

- change implementation of splash banner to a pop-up modal dialog with version string
- fixed menubar integration on Mac OS X
- fixed an issue with auto cuts saved parameters not being loaded correctly
- fixed an issue with certain auto cuts methods not getting enough samples when the image size is very small
- removed old, deprecated StandardPixelRenderer
- RGB mapping has been refactored to use a pipeline
- Removed deprecated preload feature
- Fix for focusing plugins that have no GUI
- Added feature to reset viewer attributes between images (can be used synergistically with the "remember" feature). See Reset (Viewer)" and "Remember (Image)" settings in the "Preferences" plugin.
- Fixed bug with pg backend loading icons
- Pick plugin settings now has options to set the autozoom and autocuts settings for the "Image" and "Contour" viewers (see "plugin_Pick.cfg" file in .../ginga/examples/configs)
- Fixed an issue with readout of values under the cursor when an image is plotted at a non-zero origin

- fixed a DeprecationWarning with jupyterw back end
- fixed a bug for Toolbar plugin that prevented N-E and N-W orientation from working as well as contrast restore
- fixes a bug in exporting ginga canvas objects to astropy regions objects and the test suite for it

- fixed getattr functionality in Bunch
- removed the "mock" backend; use "pil" backend for similar purposes
- fixed a longstanding issue where events registered on a canvas could be masked by default key/cursor bindings (not associated with a mode). This meant, for example, that only certain keystrokes could be captured by an event handler registered on a ginga canvas, because any keystrokes that had a default binding would take precedence. Now such bindings are only executed if the event is not handled by any active canvas bindings.
- Removed the "Quick Mode" and "From Peak" options in the Pick plugin to simplify operation.
- Many deprecated camelcase (non-PEP8) methods were removed. Use the "snake-case" names instead.
- Fixed an issue with setting the scale manually in the Preferences plugin
- Fixed a bug that can cause an incorrect cropping of image when the window is resized
- Refactor modes from Bindings module into separate modules:

- modes can now be written and understood as having a very similar structure to a plugin.
- mode docstrings can be written and maintained better to document the modes and the code implementing a mode is much easier to understand since it is encapsulated rather than all mixed together in one huge file.

- Added an AutoLoad plugin that can monitor a folder for new files and load them.
- Fixed a bug in the Overlays plugin where the overlay value was reported as the value under the cursor rather than the data value
- Fixed an issue with loading RGB images with opencv-python
- Fixed an issue where manual cut levels changes weren't reflected in the Thumbs icon
- ScreenShot now correctly captures the background color of the viewer
- Fixed a DeprecationWarning related to use of entry points
- File loaders are now discoverable under the "ginga_loaders" entry point. Loaders can be registered for MIME types and a ``mime.types`` file can be added to your ``$HOME/.ginga`` to identify types by file extension.
- ColorMapPicker plugin can now be launched as a local or global plugin
