Midas 2026.04.0

Changes

QPE preprocessor is now done before doing VCC, instead of after. This will make it less obscure to use the truncated operator in a VCC calculation.
Primitive Basis summary is now printed as part of running VSCF, if Basis Io level is high enough (4 or above).
"Bplines" is now "BSPLINE" and "Gauss" is now "GAUSSIAN", when defining non-autogenerated basis sets.
Running midascpp with --use-gdb will no longer automatically run the program. One will now manually need to use the run command.
Updated OLD iterative eigensolver to be more robust when complex eigenvalues are encountered.

Bugfixes

Fixed an issue where the FreqAna module was not able to use a custom path for the property info file. You can now provide a an absolute path or a path relative to <maindir>/setup/.

Source code changes

Removed gBasisIoLevel. Each BasDef now has a local IoLevel.

Let us know if you encounter any problems.
