+# ValCont News
+
+## ValCont 0.2.0
+
+### Added
+
+- `MDScontent()` for multidimensional scaling maps of item-trait correspondence.
+- `LuAgree()` for estimating Lu's agreement coefficient.
+- `HTmult()` for Hinkin-Tracey indices.
+- `minimumCV()` for Wilson-based minimum sample-size or critical-value calculations.
+- Additional public and supporting functions for content validity analyses, including `CVIpub()` and `Vaikenpub()`.
+- GitHub Actions workflows for cross-platform package validation and source-package release archives.
+
+### Changed
+
+- Added explicit validation for missing data across the package functions.
+- Refactored MER confidence-interval calculations and improved code consistency.
+- Improved plotting support using `ggplot2` and added MDS plotting functionality.
+- Expanded and regenerated package documentation.
+- Updated package metadata, namespace exports, dependencies, and repository documentation.
+
+### Fixed
+
+- Corrected documentation, namespace, and package-structure issues identified during CRAN-style validation.
+- Improved handling of package examples and test execution.
+
+## ValCont 0.1.0
+
+Initial public version of `ValCont`, including:
+
+- Content validity coefficients such as CVC, CVI, CVIR, CVR, MER, and Aiken's V.
+- Asymmetric confidence intervals for bounded content validity coefficients.
+- Functions for comparing independent content validity coefficients.
+- MOVER-R confidence intervals for ratios of independent coefficients.
+- Functions for evaluating rating homogeneity.
+- Basic plotting functions for validity-coefficient results.
