Other developments and bug fixes introduced to AMBER 6.8 include the following:

• enabling parameter editor ‘Check’ and ‘Expand Options’ when parameters are locked / QA-approved to support exploring parameters in case files using these features;
• various improvements for interacting with the spatial view including dragging spatial points to the corner of the model, ensuring the grid spacing persists on reloading a case and snapping points to the grid when clicking to add points;
• permitting observer parameter expressions to be checked within the parameter editor;
• resolving evaluation issues for self-referable parameters with dual multiplicity which could prevent calculations from proceeding;
• when using Batch Mode, making the handling of the working directory from control files more intuitive with relative paths and resolving an issue with the LOAD command failing to find the ADF file for an already calculated case; and
• updating supported operating systems to be Windows 10 and Windows 11.
