This minor release of ``pyvista==0.29.0`` includes a variety of changes and new features. The most major is improving our load-time by only loading in the VTK libraries used through lazy loading or selective imports using `vtkmodules``.

Jupyterlab Streaming and New Features

This release, ``pyvista==0.27.0``, is a major release that includes an important new feature for jupyterlab: real-time streaming leveraging `ipyvtk-simple`. Using either software or hardware rendering (as supported by VTK), you can visualize geometry on a remote machine through a jupyterlab environment!

Several other new features were added, along with many bug fixes and optimizations by both new and existing contributors. Thanks all for your contributions! ``pyvista`` would not be possible were it not for the community of developers behind all these PRs.
