Changes in version 1.5 (2025-08-25)                   

  - plot_dist has been rewritten to adapt to ggplot2 4.0.0 changes, and
    to make it more intuitive to interpret

  - Dependency gghalves has been removed

  - Many fixes and updates to documentation

                         Changes in version 1.4                         

  - dgr_table() now provides geometric means by default

  - gm() now provides options to strip NA values (na.rm) and
    non-positive values (neg.rm) before computation.

                  Changes in version 1.3 (2023-02-21)                   

  - Added NCA parameter estimation to calc_derived_1cpt(),
    calc_derived_2cpt() and calc_derived_3cpt(), if dose and other
    required information (e.g. tinf, dur, tau) is provided.

  - Added a warning about flip-flop kinetics and their potential effects
    on derived half-lives to calc_derived_1cpt(), calc_derived_2cpt(),
    and calc_derived_3cpt().

  - Added blq_trans() and blq_log_trans() for assistance with
    visualization of measurements below a limit of quantification.

  - Added a test for valid XML to read_nm().

  - Small fixes and enhancements to read_nmtable_single() and
    read_nm_multi_table() to ensure that stray text is properly handled
    while reading in NONMEM output files.

  - count_na() now throws a warning if NaN values are included in the NA
    count, and indicates how many of them there are.

  - Changed the significant digits functionality for 95% confidence
    intervals for get_theta(), get_omega() and get_sigma(), and all
    functions that apply these.

  - Replaced gridExtra with patchwork.

  - Numerous small fixes.

  - Removed some unnecessary dependencies.

  - Added many new unit tests, increasing test coverage considerably.

                        Changes in version 1.2.4                        

  - Fixed some minor documentation issues. Thanks to Julien Grassot for
    spotting these.

                 Changes in version 1.2.3 (2022-04-06)                  

  - Fixed another error in sample_uncert() which was still crashing the
    function.

  - Added helper functions count_na(), dgr_table(), gcv(), fmt_signif().

  - Added distribution plotting function plot_dist().

                        Changes in version 1.2.2                        

  - Fixed an error in sample_uncert() which was crashing the function.

                 Changes in version 1.2.1 (2020-08-26)                  

  - Added vignette describing PK curves.

  - Fixed a systematic error in calc_sd_1cmt_linear_oral_0_lag(),
    calc_ss_1cmt_linear_oral_0_lag(), calc_sd_2cmt_linear_oral_0_lag()
    which resulted in incorrect curves being plotted.

                         Changes in version 1.2                         

  - Rewrote plot_scm function to produce tree diagrams via DiagrammeR.

  - Fixed a rare bug in get_auc in which measurements from different
    individuals could be erroneously mixed.

  - Amended (or added) read_nm(), read_nm_all(), read_nmext(),
    read_nmcov(), read_nmtables() functions to allow reading of multiple
    NONMEM estimation steps.

  - Clarified documentation for calc_derived().

  - Now using xml2 to read NONMEM-generated XML files.

  - Fixed partial argument match warnings encountered during tests.

  - Add function for calculting geometric CV.
