  - NULL is not longer considered to be atomic in future versions of R
    (c.f.
    https://stat.ethz.ch/pipermail/r-devel/2023-September/082892.html).

  - Error messages now provide more information about error locations,
    e.g., the position of the first missing element in a vector.
  - If the object to check is missing, assert-functions now give a
    better error message, test-functions are always FALSE and
    expect-functions always raise an exception.
  - Checks for missingness and sort order optimized for ALTREPs.
  - The calling frame reported in assertions is now identical to the
    calling frame reported by R's stop() function (#117).

  - Added abbreviation "p" to qassert to check for POSIXct objects.
  - Added argument coerce to assertCount/assert_count,
    assertInt/assert_int and assertIntegerish/assert_integerish which
    optionally coerces x to integer after an successful assertion. This
    supersedes the functions asCount, asInt and asInteger (#77).
  - Added arguments max.rows and max.cols to check for maximum number of
    rows and columns for matrices, data.frames, tibbles and data.tables.
  - Added argument disjunct.from to *Names.
  - Fixed an error message in checkChoice.

  - New functions to test bit vectors implemented in package bit.
  - New functions to test R6 classes implemented in package R6.
  - Always load (not attach) the respective namespace if checking for
    objects of type data.table, tibble, R6 or bit. This ensures that all
    operations work as expected after the check.
  - *Names with type="unnamed" now works with NULL.
  - New argument must.include for *Names.
  - Fixed possible protection stack imbalance as reported by rchk.

                 Changes in version 1.8.3 (2017-07-03)                  

  - New argument sorted (defaults to FALSE) for *Integer, *Integerish
    and Numeric to check for ascending order of vector elements.
  - New argument null.ok (defaults to FALSE) for *Choice and *Class.
  - *Subset now allows to pass empty vectors to choices.
  - Improved error message for *Choice.
  - The set family of functions is now more restrict regarding the
    class, e.g. they differentiate between factors and characters.
  - *Character and *String now ignores missing values in regular
    expressions and for string length checks (using argument min.chars).
    To disallow missing values, set any.missing or na.ok, respectively.
  - *Date now ignores missing values in for lower/upper bound checks. To
    disallow missing values, set any.missing to FALSE. Thanks to Will
    Beasley (@wibeasley) for the PR.
  - Package microbenchmark is no longer strictly required to build the
    vignette. If not installed, some output and figures will be missing
    though.

    storage type via argument "mode".
  - Functions *Count, *Int, *Number, *Integer, *Integerish and *Numeric
    do not accept logical values any more.
  - checkAtomicVector is now more restrictive and prohibits a dimension
    symbol. Thus, a matrix is not considered an atomic vector any more.
  - Dropped support for AssertCollections in convert functions (asInt,
    asInteger and asCount).
  - Added checkTibble.

                 Changes in version 1.8.1 (2016-06-28)                  

  - Function test_file is longer exported.
  - *Function does not longer lookup functions with match.fun. As a
    result, passing functions via the string of the function name
    stopped working.
  - In qassert using f as first char in a rule now specifies factor
    (before: function).

                 Changes in version 1.8.0 (2016-06-06)                  

  - Most functions now support the handling of default arguments encoded
    as NULL via argument null.ok.
  - Functions *File and *Directory are deprecated due to name clashes
    and will be removed in a future version. Please use *FileExists or
    *DirectoryExists instead.
  - New helper function matchArg to provide a simple an easy way for
    partial argument matching in combination with an AssertCollection.
  - Added alias functions for all check functions (check_*) to provide
    support for the underscore programming style in assert().

                 Changes in version 1.7.4 (2016-04-08)                  

  - Compatibility with the upcoming testthat version.
  - expect_ functions now return the checked object invisibly.
  - Changed default of argument .var.name for assertions and label for
    expectations: They now default to the return value of the exported
    function vname (instead of missing which confuses some linters).
  - Fixed error message in convert functions: Variable name was not
    properly looked up by the heuristic.
  - Fixed a bug in qassertr and qtestr where the error message was not
    properly generated if multiple rules were provided.
  - New argument depth for qtestr to control the recursion depth while
    checking nested lists.

                 Changes in version 1.7.2 (2016-02-25)                  

  - Added checkOS().
  - Argument fixed for *Character functions now accepts a string instead
    of a boolean value and thus can directly be used for a substring
    search.
  - New arguments min.chars, pattern, fixed and ignore.case for the
    *String family of functions.
  - Exported helper functions wf (which.first) and wl (which.last).
  - Now importing the new backports package for functions lengths() and
    dir.exists.

                 Changes in version 1.7.0 (2016-01-23)                  

  - Added alias functions for all functions to support the underscore
    style, e.g. assert_numeric is the new alias for assertNumeric and
    test_matrix is the alias for test_matrix.
  - All assert functions now invisibly return the tested object instead
    of TRUE and thus can be used with magrittr pipes.
  - Improved speed for most functions by reducing the .Call overhead
    (Thanks to Hadley Wickham).
  - Added *DataTable functions to properly test primary and secondary
    keys of data tables.
  - Removed *Percentage family of functions.
  - Exported functions makeAssertion, makeTest and makeExpectation to
    assist expanding the package with user-generated checks.

  - The default for the parameter "ordered" of the *SetEqual functions
    is now set to FALSE, as described in the documentation.

                 Changes in version 1.6.2 (2015-07-26)                  

  - Fixed a compile-time warning.
  - checkmate does not import testthat anymore in order to speed up
    package loading times and to keep the dependencies at a minimum. The
    expect_* family of functions can still be used, the namespace will
    be loaded on demand.

                 Changes in version 1.6.1 (2015-07-17)                  

  - New family of functions: expect_* is intended to be used in
    combination with testthat. But note that functions expect_null() and
    expect_named() are not provided to avoid name clashes with testthat.
