Changes in version 1.0.5 (2026-05-04)                  

  - Resubmission addressing CRAN reviewer (Benjamin Altmann) feedback
    on 1.0.4:
      - Added DOI / ISBN links to all references in the Description
        field (Hsiao 2014, Swamy 1970, Pesaran 2004).
      - Removed the surrounding single quotes around function names in
        the Description text and added trailing parentheses, e.g.
        'xtpretest'-> xtpretest().
  - Synchronised CITATION version with DESCRIPTION (1.0.5).
  - No code or behavior changes.

                        Changes in version 1.0.4                        

  - Resubmission to CRAN.
  - Removed UTF-8 BOM (Byte Order Mark) from inst/CITATION and from
    R/xtcsdq.R, R/xtmispanel.R, R/xtqsh.R. The BOM in inst/CITATIONwas
    causing the CRAN incoming auto-check to fail with: Invalid citation
    information in 'inst/CITATION': 1:1: unexpected input.
  - Synchronised the version string in inst/CITATION with DESCRIPTION.
  - No code or behavior changes.

                        Changes in version 1.0.3                        

  - Resubmission. Removed redundant "a suite of tools for" from the
    Description start. All references use doi:10.xxx format.
