Changes in version 1.2.0 (2022-11-15)                  

  - Fix CRAN warning of about bitwise '|' with boolean operands
    [-Wbitwise-instead-of-logical]
  - Improved documentation of queue_step()
  - Waiting times are now forced to be zero since floating-point error
    can make waiting times slightly negative.

                 Changes in version 1.1.0 (2021-04-09)                  

  - Fix bug with integer inputs #34, particularly if server input is of
    class integer.

                 Changes in version 1.0.0 (2020-10-06)                  

  - Added citation to our published paper.

                 Changes in version 0.8.3 (2018-10-16)                  

New features

  - Information about final state of servers is returned as state list
    element from queue_step output

Notes

  - adjust argument is removed
  - updated citation() information
  - Changed license from GPL (>= 2) to GPL-2 only

                 Changes in version 0.8.2 (2017-11-17)                  

New features:

  - Much faster queue lengths computation. This means queue_step() is
    faster. The speed of queue() is unaffected.

Bug fixes

  - queue_step no longer errors if arrivals is an integer vector
  - summary.queue_list now returns a warning rather than an error if a
    server.list object is inputted.

                 Changes in version 0.8.1 (2017-04-11)                  

New features:

  - Much faster summary method
  - Plotting methods for queues
  - New function create_batches to easily create batch arrival systems.

                 Changes in version 0.6.1 (2016-12-20)                  

New features:

  - It's faster. We accomplish this by checking whether arrival times
    are already ordered (in which case we skip reordering!) and by using
    the "radix" method within the order function.
  - Internal queue function for high level users
  - Customers can now miss the queue if they arrive too late.

Bug fixes:

  - queue_step with as.server.stepfun now checks if departure times
    force move to next epoch. Previously (in some cases) new customers
    could be served by servers in previous epochs.
  - Added extra checks in queue_step and as.server.stepfun for correct
    input.

                 Changes in version 0.5.1 (2016-11-15)                  

  - Released to CRAN
