Flatpak Release

Flatpak users can download the SasView flatpak from flathub: https://flathub.org/apps/org.sasview.sasview.

Wheel

SasView is now available to install via the pip package manager. You can install it to an environment with the command:

pip install sasview

Alternatively, you can use the uv tool to run SasView with the following command:

uvx sasview

This will automatically create a virtual environment, install SasView to it, and run SasView.

Known Issues

Neither the Add/Multiply Editor or the Plugin Model functionality are working in SasView 6.1.1. We would like to apologise for any inconvenience and are urgently working to rectify these deficiencies. In the meantime, if you need to create a model with Add/Multiply please install SasView 6.1.0. If you have an existing plugin, or have downloaded a model from the Marketplace and wish to use it in SasView 6.1.1, copy the relevant .py/.c files to the \sasmodels\models sub-folder in your SasView installation folder and restart the program.

All known bugs and feature requests can be found in the issues on github.
