Changes in version 0.6.1 (2026-02-16)                  

Reducing minimum R version

  - Reduced minimum R version required from 4.3.0 to 4.2.0, following
    the reduction in package rvec.

Bug fix

  - Discovered that function ex_to_lifetab_brass() was using a
    non-standard formula (applying logit to lx rather than 1 - lx).
    Hard-deprecated the function, and created a new function,
    e0_to_lifetab_logit(), that uses the correct formula.

                        Changes in version 0.6.0                        

Interface

  - Extended .intrinsic_growth_rate() to allow for rvec mx and Lx
    arguments.
  - Improved documentation for tfr_to_asfr_scale() and
    ex_to_lifetab_brass().

                 Changes in version 0.5.0 (2026-01-12)                  

Interface

  - Renamed iran_fertility to irn_fert.
  - Renamed nzmort to nzl_mort.
  - Renamed nzmort_rvec to nzl_mort_rvec.
  - Added function .intrinsic_growth_rate() to calculate growth rate
    associated with fertility, mortality schedules. Fairly low level -
    more user-friendly functions calling intrinsic_growth_rate() will be
    added in due course.
  - ex_to_lifetable_brass() returns a tibble rather than a base R data
    frame.
  - asfr argument for tfr() now defaults to asfr.

Internal calculations

  - to_matrix() now uses rlang::all_of() with tidyselect arguments, to
    avoid deprecation warnings.

                 Changes in version 0.4.2 (2025-07-12)                  

Interface

  - Modify function rr3 to use C code. (#30)
  - Modified tests for upcoming changes to package rvec (where random
    variant functions for discrete distributions will always return
    doubles).

                 Changes in version 0.4.1 (2025-03-27)                  

  - Modify C++ function qx_to_ex() to avoid possible memory leekage
    found by valgrind.

                 Changes in version 0.4.0 (2025-03-23)                  

Interface

  - If data already contains columns called "lx", "Lx", "dx", "ex", then
    lifetab() overwrites these columns, with a message, rather than
    creating new versions.
  - at argument to lifeexp() can now be a vector with length
    1.  In this case, lifeexp() calculates life expectancy for each
        value (within each combination of the 'by' variables, if
        present.)

  - Added n_core argument to lifetab() and lifeexp(). Setting n_core to
    a value greater than 1 triggers parallel processing.
  - Added closed argument to check_age(), to check whether the oldest
    age group is closed.
  - Added function tfr() for calculating total fertility rates.
  - Extended vignette.

Bug fixes

  - combine_age() previously not working properly if "to" is "five", and
    lower limit of youngest age group in x not divisible by 5.
  - ex_to_lifetab_brass() previously assumed, without checking that age
    groups were correctly ordered. ex_to_lifetab_brass() now
    automatically reorders them.

                 Changes in version 0.3.3 (2024-09-14)                  

Bug fixes

  - Previously calling lifetab() with value supplied for qx created a
    duplicate qx column in the result. The extra column has been
    removed.

Interface

  - Added at argument to lifeexp().
  - Removed mx column from output of lifetab() when calculated from mx
    (to be consistent with behaviour of lifetab() when calculated from
    qx.)

New functions

  - Added function check_n().
  - Added function q0_to_m0().
  - Added function rr3().
  - Added function trim_01().

Internal

  - Removed stop(gettextf( style error messages, except in functions
    involving age (which will be superceded by package agetime.

                        Changes in version 0.3.2                        

Internal

  - Removed all uses of rvec::rvec.is.numeric(), in preparation for
    removing from rvec package.

Bug fixes

  - Fixed bug in combine_age(). Previously giving wrong answers when
    last age group was closed.

                 Changes in version 0.3.1 (2024-06-12)                  

Bug fixes

  - Fixed "lifetab.cpp:455:16: runtime error: inf is outside the range
    of representable values of type 'int'" - changed nx from int to
    double

                 Changes in version 0.3.0 (2024-05-24)                  

  - Released on to CRAN

                        Changes in version 0.2.0                        

  - Coverage of tests 100 percent
