28 Mar 2022 `1139 <https://github.com/enthought/mayavi/pull/1139>`_ (prabhuramachandran)
- Refactor jupyter backends and add support for using itkwidgets_. This
allows us to use Mayavi in a headless manner unlike the other backends
which require offscreen support.

backend.

============

This is primarily a bugfix release that resolves issues with VTK-9.0.3 and
VTK-9.1.x compatibility. CI now uses GitHub Actions and a few other minor bugs
have been fixed. `mlab` imports may be a little faster thanks to some cleanup.

============

The significant update for this release is that it is compatible with the
latest VTK-9.x series and is known to work with VTK 9.0.1 from PyPI. The
picker UI has changed to no longer pop up a UI window but instead show the
picked attributes on the render window directly. The original picker UI is now
available on the scene's UI in a separate "Picker" tab. This is accessible
from either the pipeline view when one edits the properties of a scene or
through the "configure scene" gear icon on the scene window toolbar.
