Changes in version 1.0.1.9000                      

New features

  - Current development version

                 Changes in version 1.0.1 (2026-01-22)                  

Bug fixes

  - Fixed NEWS.md format to comply with CRAN requirements (ISO 8601
    dates and proper heading levels)

                 Changes in version 1.0.0 (2021-01-13)                  

New features

  - Version number bumped to 1.0.0 to correspond to publication of JSS
    paper.

                        Changes in version 0.2.5                        

Bug fixes

  - Fix bug where infinite survival time were incorrectly returned as
    NaN (due to: Inf * d = NaN when d = 0 is for a censored individual)

                        Changes in version 0.2.4                        

New features

  - Allow negative shape parameters for the Gompertz distribution (note
    that this can lead to infinite survival times, in which case the
    survival time is set to 'Inf' and a warning is printed).

Bug fixes

  - The simsurv() function documentation and the technical vignette have
    been updated to better clarify the parameterisations for the
    parametric distributions.

                 Changes in version 0.2.3 (2019-02-01)                  

New features

  - The rootfun argument has been added. This allows the user to apply
    any transformation to each side of the root finding equation. The
    default is rootfun = log which corresponds to uniroot solving -H(t)
    - log(u) = 0.
      - The rootsolver argument has been added. This allows the user to
        choose between stats::uniroot or BB::dfsane for the root
        finding.

                 Changes in version 0.2.2 (2018-05-18)                  

New features

  - The uniroot function (called internally by simsurv) now solves -
    H(t) - log(u) = 0 instead of exp(-H(t)) - u = 0, i.e. it is on log
    scale.

                        Changes in version 0.2.1                        

Bug fixes

  - The interval argument of simsurv supports a lower limit of zero
    (thanks to Alessandro Gasparini, @ellessenne).

                 Changes in version 0.2.0 (2018-03-06)                  

New features

  - Added technical and example usage vignettes
      - Added user-specified cumulative hazard or log cumulative hazard
      - Added analytical forms for the inverted survival function when
        generating survival times from standard distributions (instead
        of using numerical root finding). This has lead to about
        a 5-fold increase in speed when simulating event times from
        standard parametric distributions.

                 Changes in version 0.1.0 (2017-07-27)
