                 Changes in version 3.2.0 (2026-09-20)                  

  - Fix reversed argument order in renewaft(): the signature was
    (SURVIVAL, prevtime, aft), inconsistent with
    renewhr()/nhpphr()/nhppaft(), causing generated renewal times to be
    computed with prevtime and aft swapped and occasionally precede the
    prior event.
    
      - Fix index overflow in s_piecewise() when only a single finite
        break is supplied (e.g. breaks = c(1, Inf)), which produced
        reversed index ranges and made the function fail with "Unsucess
        scale".
    
      - Fix s_gompertz() silently generating NaN for a negative shape
        (decreasing hazard). Draws that fall into the resulting cure
        fraction now correctly return Inf instead of NaN. See the new
        "Negative shape" documentation section for s_gompertz().
    
      - Fix numerical truncation to Inf in s_lognormal()'s invCum_Hfx()
        and Cum_Hfx() for large cumulative hazards / late times, caused
        by probabilities underflowing to exactly 0 or 1 in double
        precision. Both now use log.p/lower.tail forms of
        qlnorm()/plnorm() to stay accurate.
    
      - Rename rsurvah()/ggplot_survival_ah() to
        rsurveh()/ggplot_survival_eh(). These generate the Extended
        Hazards model of Chen & Jewell (2001) (h*(t) = hr * aft * h0(aft
        * t), nesting proportional hazards and accelerated failure time
        as special cases), not the Accelerated Hazards model of Chen &
        Wang (2000) as the previous name implied. This is a breaking
        rename with no deprecated alias.
    
      - Improve documentation and vignettes

                 Changes in version 3.1.1 (2024-08-16)                  

Fix graph after simulation to start in survival 1 at time 0 and
cumulative risk 0 at time 0
