Full Changelog: v6.2.0a2...v6.2.0a3

SasView 6.2.0 Alpha2

Due to a packaging issue with fibonacci.py in sasmodels, the installers for alpha 1 did not include the new models.

This alpha fixes that.

Please find the complete list of changes included in the release notes for v6.2.0a1.

SasView v6.1.3

New in Version 6.1.3

This is a minor bug fix release of SasView. This release is built using Python v3.11, Sasmodels v1.0.12, Sasdata v0.11.0, and Bumps v1.0.2.

MacOS Intel Support - Advisory

This will likely be the final SasView release with full MacOS Intel processor support.

Pypi distribution and wheel installation

This release depends on pkg_resources which was removed from the setuptools package as of v82.0.0. This requirement was overlooked in our distribution list, so the sasview wheels currently try to use the latest version of setuptools, which is not compatible with this release. To fix the issue when installing SasView using standard Python installation tools, please run uv pip install sasview setuptools==81.0.0 (or pip install sasview setuptools==81.0.0).

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.
