Changes in version 0.2.1 (2026-09-02)                  

  - Comprehensive Graphical Engine Refactoring (plot_agri_graphics):
    
      - Fully restored and optimized all plotting modules (residual,
        correlation, mean, pca, cluster, and path) with zero data loss.
      - Resolved hardcoding issues, label bugs (such as G-1, G-2 naming
        conflicts), and color palette limitations across all
        visualization types.
      - Implemented dynamic text sizing (cex) and automated genotype
        aggregation in PCA biplots to eliminate text overlapping and
        ensure clean rendering for large datasets.
      - Added unconstrained dynamic color palettes in circular
        dendrograms to support unlimited cluster groups smoothly.
      - Configured robust graphics state safety guards (on.exit and par
        restoration) to prevent graphical device leaks during residual
        and circular cluster plotting.

  - Package Infrastructure & CRAN Compliance:
    
      - Updated version number to 0.2.0 to reflect major functional
        enhancements and critical bug fixes.
      - Integrated official BugReports and GitHub repository metadata
        links into the DESCRIPTION file.
      - Enhanced internal error-handling and input validation routines
        for all analytical payloads across statistical modules.

                 Changes in version 0.1.2 (2026-08-08)                  

  - Initial structural deployment of the core infrastructure.
  - Integrated complete analytical engines for CRD and RCBD Analysis of
    Variance (ANOVA).
  - Added multiple group comparison post-hoc matrices (LSD, Tukey, and
    Scheffe testing blocks).
  - Integrated core statistical functions including Summary Statistics,
    Correlation Analysis, Path Coefficients, and Principal Component
    Analysis (PCA).
  - Finalized multivariate clustering modules (Hierarchical
    Agglomerative Clustering) and multi-trait plotting systems.
