What's Changed

This is a point release which fixes a number of issues reported in earlier versions
of 5.0.x. Of particular note, the failure of the program to start when installing on
a new system due to issues finding the config file has been fixed. The speed with
which the program starts up has also been improved. The paracrystalline models, which
have been labelled as "under review" since 2018, have been checked and corrected (bcc
and fcc) and the documentation completely reworked (bcc, fcc, and sc). The SasView
Development Team would very much like to express their sincere gratitude to those
members of the community that assisted with this task. Elsewhere, plots now properly
support custom data names in the legend, the LM optimizer failing to run on GPUs or
when the starting value of a parameter is outside the min/max range has been fixed,
a problem with the intermittent blanking of plots has also been fixed, a number of
defaults have been changed to be more reasonable, and a number of other issues in
the documentation have been corrected and/or updated.

Known Issues

Jul 14, 2023: There appear to be circumstances where the SasView 5.0.6 installer
targets an existing SasView folder for the installation of the new version. If v5.0.6
installs to/overwrites an existing version of SasView it may fail to run and throw errors
such as 'ImportError: DLL load failed while importing...'. To avoid this, install v5.0.6 to
its own folder.

Feb 13, 2023: The Development Team is aware of a (so far isolated) instance of
v5.0.6 failing to run on MacOS 13.1 (Ventura). For some reason during installation
~.sasview\config\custom_config.py was created as a folder and not as a file.
Should you experience this, delete the custom_config.py folder and replace it with a
copy of the file https://github.com/SasView/sasview/blob/release_5.0.6/src/sas/sasview/custom_config.py

All the known bugs/feature requests can be found in the issues on github.
Note the sasmodels issues are now separate from the sasview issues (i.e. different repositories)
