Description

napari 0.7.1

⚠️ Note: these release notes are still in draft while 0.7.1a1 is in prerelease testing. ⚠️

Thu, May 14, 2026

We're happy to announce the release of napari 0.7.1! 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.

napari follows EffVer (Intended Effort Versioning); this is a Meso release containing awesome new features, but some effort may be needed when updating previous projects to use this version.
