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).
For more information, examples, and documentation, please visit our website: https://napari.org/
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](https://github.com/napari/napari/pull/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](https://github.com/napari/napari/pull/7100)).
See below for the full list of changes!
