Description

napari 0.6.2

⚠️ Note: these release notes are still in draft while 0.6.2 is in release candidate testing. ⚠️

Mon, Jun 23, 2025

We're happy to announce the release of napari 0.6.2! 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).

For more information, examples, and documentation, please visit our website, https://napari.org.
