napari 0.3.5

We're happy to announce the release of napari 0.3.5! napari is a fast, interactive, multi-dimensional image viewer for Python. It's designed for browsing, annotating, and analyzing large multi-dimensional images. It's built on top of Qt (for the GUI), vispy (for performant GPU-based rendering), and the scientific Python stack (numpy, scipy).

This release contains a number of bug fixes on various platforms. For those interested in napari performance, we have added a new performance monitoring mode, that can be activated by the NAPARI_PERFMON environment variable, see (#1262) for details. We have also added a page in the explanations section of our docs on napari's rendering including plans for the future.
