Changes in version 1.0.2 (2026-02-03)

      - Fixed the expression of Ed2llk_matsu for Matsuoka distribution

                 Changes in version 1.0.1 (2026-01-22)                  

  - Minor Revision
      - Fixed the signal of Ed2llk_ul for Unit-Lindley distribution
      - Fixed a constant in Ed2llk_uw for Unit-Weibull distribution

                 Changes in version 1.0.0 (2025-06-18)                  

  - Minor changes
    
      - Renamed several modules and moved functions and subroutines for
        better file organization.
      - Removed 00_specfun module; migrated trigamma and psi to
        00_lib_utils. Other functions in 00_specfun are no longer
        necessary. The COPYRIGHTS and DESCRIPTION files have been
        updated to reflect the changes.
      - Consolidated 03_barfima, 03_karfima, 03_garfima, and 03_uwarfima
        into a single module named 05_generic.
      - Simplified the internal structure of the link.btsr function.

  - Major Changes
    
      - Rewrote and renamed 01_RNG to 01_distrib.f90, now using R's
        native rand_unif, rbeta, dbeta, rgamma, and dgamma. The
        COPYRIGHTS and DESCRIPTION files have been updated to reflect
        these changes.
      - Modified subroutines in 02_base to support time-varying nu.
      - Added input validation and variable conversion functions for
        backward compatibility.
      - The btsr.sim, btsr.extract, and btsr.fit functions have been
        updated to support the new models. Regression models can now be
        easily fitted using these functions.
      - Fixed parameter initialization typo:
        Old: sigma2 <- sum(er^2)/((n1 - k) * (dlink)^2)
        New: sigma2 <- sum(er^2/((n1 - k) * (dlink)^2))
      - Changed the initialization of xreg from zero to the mean of the
        first p observations.
      - Added a robust covariance calculation method that falls back to
        the outer product of gradients if Hessian calculation fails.

                 Changes in version 0.1.5 (2023-09-23)                  

  - Minor Revision

  - Added the "_PACKAGE" special sentinel to fix the problem related to
    the fact that @docType package no longer automatically adds a
    -package alias.

  - Temporary disabled all subroutines that use integer(kind=8)
    (file 01_RNG.f90).

  - Fixed the ``not yet implemented: derived type components with non
    default lower bounds'' message due to mag01 component in 01_RNG.f90
    file and changed subroutines that use this component accordingly.

                 Changes in version 0.1.4 (2023-01-20)                  

  - Minor fix

  - We fixed some typos in src/BTSR_init.c and added the information
    about this file to src/Makevars (this was missing in the last
    version)

  - Internal subroutines to simulate, extract and fit models were
    modified, but this caused no change in the results from previous
    versions. This change was done since using a construction such as
    'foo <- .check.model(model[1], "extract")' and then
    '.Fortran(foo,...)' gives an error during the registration process.
    Therefore, we created auxiliary functions for each model.

  - We have fixed a typo in the FORTRAN subroutine used to predict BARC
    models. This should fix the memory allocation problem found in the
    last version.

                 Changes in version 0.1.3 (2023-01-11)                  

  - Minor fix

  - We have added the file src/BTSR_init.c

                 Changes in version 0.1.2 (2022-11-18)                  

  - Minor fix

  - 00_lb.f90 was merged with 00_lbfgsb.f90

  - We have added more information to src/Makevars in order to setup
    dependencies for parallel make.

                 Changes in version 0.1.1 (2022-11-13)                  

  - Minor fix

  - We have added explicit dependencies to src/Makevars to tell make the
    constraints on the order of compilation.

                 Changes in version 0.1.0 (2022-11-08)                  

  - First version
