Changes in version 4.0.0 (2019-01-22)                  

  - Adapt return_value of simtimer::sim_wday() to a character, giving
    the weekday number ("1" = Monday, "2" = Tuesday, ..., "7" = Sunday).
    Before this function returned the abbreviated weekday (depending on
    base::Sys.getlocale()). The new solution therefore improves platform
    independency.
  - decoupling of lubridate package by replacement with base functions.

                 Changes in version 3.0.0 (2017-12-21)                  

  - Added a NEWS.md file to track changes to the package.
  - Basic functionality as described in readme.md and vignette.
