This release introduces major modules for data preprocessing and item analysis, alongside enhancements to the CFA workflow.

• Item Drop Out: Introduced the “Item Drop Out” module (formerly Item-Rest) to facilitate automated item elimination strategies for optimizing scale properties and factor structures.
• CFA Module Updates: Enhanced the Confirmatory Factor Analysis (CFA) module, specifically improving the “Model Builder” to allow for easier definition of covariances and model specifications.
• Reliability Analysis: Added support for
• Stratified Alpha coefficient calculation to better assess reliability in multidimensional scales.

These binaries (installable software) and packages are in development.
