napari 0.3.3#

We’re happy to announce the release of napari 0.3.3! 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 is a small bug fix PR that pins our Qt version at < 5.15.0, due to incompatibilities with their latest release until we fix them. See #1312 for discussion and the latest progress.
