Changes in version 2.0.0                        

  - Updated documentation
  - Replaced mclapply() calls with parLapply() to make parallelization
    available on Windows machines.
  - Renamed "exact" to "series".
  - Improved numerical stability in nb_sum_series().
  - Improved approach to/automated selection of the number of series
    terms included in the series method.
  - Fixed a bug in the implementation of saddlepoint normalization.
  - Added the FFT-based evaluation method.
  - Add the 'hybrid' evaluation method that combines the FFT-based
    method with the series method when extreme values are required.

                 Changes in version 1.0.1 (2023-07-06)                  

  - Fixed bug in nb_sum_saddlepoint() that could lead to NaN errors when
    solving the saddlepoint equation with stats::uniroot().
  - Added parallelization in rnbconv() to speed up large-scale sampling.
  - Updated notation in nb_sum_saddlepoint() for clarity.
  - Added additional checks to ensure: 0 < ps <= 1, mus >= 0, phis > 0.

                 Changes in version 1.0.0 (2023-04-27)                  

  - nbconv is on CRAN!

                     Changes in version 0.0.0.9000                      

  - Added a NEWS.md file to track changes to the package.
