Monday, Aug 12, 2024

We're happy to announce the release of napari 0.5.2!

napari is a fast, interactive, multi-dimensional image viewer for Python. It's designed for exploring, annotating, and analyzing multi-dimensional images. It's built on Qt (for the GUI), VisPy (for performant GPU-based rendering), and the scientific Python stack (NumPy, SciPy, and friends).

Highlights

This is primarily a bug-fix release, but we snuck a couple of new features in there, including smoother, prettier, better rendering of Labels volumes in 3D (#7100) and the ability to display scale bar at a fixed length in world coordinates, rather than having it resize dynamically to take up a small part of the screen (#7167).
