\section{Changes in anytime version 0.3.8 (2020-07-23)}{
  \itemize{
    \item A small utility function was added to detect the Linux
    distribution used in order to fine-tune tests once more.
    \item Travis now uses Ubuntu 'bionic' and R 4.0.*.
  }
}

\section{Changes in anytime version 0.3.7 (2020-01-20)}{
  \itemize{
    \item Test and possibly condition away one more test file.
    \item Small enhancement for compilation by setting \code{no-rtti}
    define via Rcpp.
    \item New option \code{calcUnique} for speed-up by parseing only
    unique timestamps (Stephen Froehlich in \ghpr{110} fixing \ghpr{109}).
  }
}

\section{Changes in anytime version 0.3.6 (2019-08-29)}{
  \itemize{
    \item Added, and then removed, required file for JOSS; added
    'unworthy' badge as we earned a desk reject (cf #1605 there).
    \item Renamed internal helper function format() to fmt() to avoid
    clashes with base::format() (Dirk in \ghpr{104}).
    \item Use S3 dispatch and generics for key functions (Dirk in
    \ghpr{106}).
    \item Continued to tweak tests as we find some of the rhub platform
    to behave strangely (Dirk via commits, \ghpr{107}, and \ghpr{108}).
    \item Added \code{\%e} format for single-digit day parsing by Boost
    (Dirk addressing at least \ghit{24}, \ghit{70} and \ghit{99}).
    \item Expansed and updated vignette with benchmark comparisons.
    \item Updated unit tests using \pkg{tinytest} which remains a
    pleasure to use; versioned Suggests: is now '>= 1.0.0'.
  }
}

\section{Changes in anytime version 0.3.5 (2019-07-28)}{
  \itemize{
    \item Fix use of \code{Rcpp::Function}-accessed \code{Sys.setenv()},
    name all arguments in call to C++ (Christoph Sax in \ghpr{95}).
    \item Relax constraint on Windows testing in several test files
    (Christoph Sax in \ghpr{97}).
    \item Fix an issue related to \code{TZ} environment variable setting
    (Dirk in \ghpr{101}).
    \item Change \code{useR=TRUE} behaviour by directly calling R via
    \pkg{Rcpp} (Dirk in \ghpr{103} fixing \ghit{96}).
    \item Several updates to unit testing files aiming for more robust
    behaviour across platforms.
    \item Updated documentation in manual pages, README and vignette.
  }
}

\section{Changes in anytime version 0.3.4 (2019-06-18)}{
  \itemize{
    \item Documentation was updated about a 'Europe/London' conversion
    issue (\ghit{84}, inter alia).
    \item The package is now compiled under the C++11 standard.
    \item The package now uses \pkg{tinytest} for unit tests.
    \item The \code{iso8601()} function now places a \sQuote{T} between
    date and time; an option switches to prior format using a space.
    \item The vignette is now pre-made and included as-is in a Sweave
    document reducing the number of suggested packages.
  }
}

\section{Changes in anytime version 0.3.3 (2018-11-13)}{
  \itemize{
    \item Vignette build quirkyness on Windows resolved so vignette
    reinstated.
    \item Documentation updated showing correct use of \code{anydate}
    (and not \code{anytime}) on input like \sQuote{2016010} following
    the 0.3.0 release heuristic change.
    \item Set \code{#define} for Boost to make compilation more quiet.
  }
}

\section{Changes in anytime version 0.3.2 (2018-11-05)}{
  \itemize{
    \item Added a new vignette introducing the \pkg{anytime} package.
    Seemingly it cannot be compiled on Windows so included prebuilt.
    \item Some more tests for \code{anydate} were added along with so
    code coverage tags.
    \item The C++ code was robustified in two places to not trigger
    \code{rchk} warnings (\ghpr{79}).
    \item Three unit test files which fail on Solaris are now skipping
    this os as we cannot reproduce or test on this OS (\ghpr{80}).
  }
}

\section{Changes in anytime version 0.3.1 (2018-07-03)}{
  \itemize{
    \item Numeric input is now preserved rather than silently cast to
    the return object type (\ghpr{69} fixing \ghit{68}).
    \item New assertion function \code{assertDate()} and \code{assertTime()}.
    \item Unit tests were expanded for the new functions, for conversion
    from integer as well as for \code{yyyymmdd()}.
  }
}

\section{Changes in anytime version 0.3.0 (2017-06-05)}{
  \itemize{
    \item Numeric input is now always an offset to epoch, with
    \code{anytime()} using seconds, and \code{anydate()} using dates.
    (\ghpr{65} fixing \ghit{63}).
    \item Old behaviour can be re-enabled with an option also supporting
    a global setting \code{getOption("anytimeOldHeuristic")}
    \item RStudio versions 1.1.129 or later can run all functions
    without fear of crashing due to a change in their use of Boost.
    \item Replaced \code{init.c} with registration code inside of
    \code{RcppExports.cpp} thanks to Rcpp 0.12.11.
  }
}

\section{Changes in anytime version 0.2.2 (2017-03-21)}{
  \itemize{
    \item Address corner case of integer-typed (large) values
    corresponding to \code{POSIXct} time (PR \ghpr{57} closing \ghit{#56})
    \item Add special case for \sQuote{Europe/London} and 31 Oct 1971
    BST change to avoid a one-hour offset error (\ghpr{58} fixing
    \ghit{36} and \ghit{51})
    \item Address another corner case of numeric values corresponding to
    \code{Date} types which are now returned as \code{Date}
    \item Added file \code{init.c} with calls to \code{R_registerRoutines()}
    \code{and R_useDynamicSymbols()}; already used \code{.registration=TRUE}
    in \code{useDynLib} in \code{NAMESPACE}
  }
}

\section{Changes in anytime version 0.2.1 (2017-02-09)}{
  \itemize{
    \item The new \code{DatetimeVector} class from \CRANpkg{Rcpp} is now
    used, and proper versioned Depends: have been added (PR \ghpr{43})
    \item The \code{anydate} and \code{utcdate} functions convert again
    from factor and ordered (PR \ghpr{46} closing \ghit{44})
    \item A format similar to RFC 28122 but with additonal timezone text
    can now be parsed (PR \ghpr{48} closing \ghit{47})
    \item Conversion from \code{POSIXt} to \code{Date} now also respect
    the timezone (PR \ghpr{50} closing \ghit{49})
    \item The internal \code{.onLoad} functions was updated
    \item The Travis setup uses https to fetch the run script
  }
}

\section{Changes in anytime version 0.2.0 (2016-12-24)}{
  \itemize{
    \item Added (exported) helper functions iso8601(), rfc2822() and
    rfc3339() to format date(time) objects according to standards
    \item Conversion to dates is now more robust thanks to improved
    internal processing (PR \ghpr{39} closing \ghit{36})
    \item The ISO 8601 format is now recognised, however the timezone
    information is not parsed by Boost Date_Time (which is a known
    upstream limitation) (PR \ghpr{38} closing \ghit{37})
    \item The 'allFormats.R' test script was significantly strengthened
    (\ghpr{40})
    \item Test scripts like 'simpleTests.R' have as also been
    strengthened (\ghpr{41}); on Windows and in one file two tests need
    to be skipped.
    \item A new 'bulkTest.R' test script was added testing parsing
    against what R returns
  }
}

\section{Changes in anytime version 0.1.2 (2016-12-13)}{
  \itemize{
    \item The (internal) string processing and splitting now uses Boost
    algorithm functions which avoids a (bizarre) bug on
    Windows. (\ghit{33})
    \item Test coverage was increased.

  }
}

\section{Changes in anytime version 0.1.1 (2016-11-27)}{
  \itemize{
    \item Both \code{anydate()} and \code{utcdate()} no longer attempt
    to convert an input value that is already of type \code{Date}.
    \item The string splitter (needed for the 'all-digits' formats
    extending Boost Date_time) is now more defensive about the input
    argument and more robust. Thanks to Bob Jansen for the heads-up
    (PR \ghpr{30} closing issue \ghit{29}).
    \item Code coverage reporting has been added (PR \ghpr{31}).
  }
}

\section{Changes in anytime version 0.1.0 (2016-11-06)}{
  \itemize{
    \item New functions \code{utctime()} and \code{utcdate()} were
    added to parse input as coordinated universal time; the
    functionality is also available in \code{anytime()} and
    \code{anydate()} via a new argument \code{asUTC} (PR \ghpr{22})
    \item New (date)time format for RFC822-alike dates, and expanded
    existing datetime formats to all support fractional seconds (PR
    \ghpr{21})
    \item Extended functionality to support not only \sQuote{YYYYMMDD}
    (without a separator, and not covered by Boost) but also with
    \sQuote{HHMM}, \sQuote{HHMMSS} and \sQuote{HHMMSS.ffffff} (PR
    \ghpr{30} fixing issue \ghit{29})
    \item Extended functionality to support \sQuote{HHMMSS[.ffffff]}
    following other date formats.
    \item Documentation and tests have been expanded; typos corrected
    \item New (unexported) helper functions \code{setTZ},
    \code{testOutput}, \code{setDebug}

    be called under RStudio (PR \ghpr{27} fixing issue \ghit{25}).
    \item More robust support for non-finite values such as \code{NA},
    \code{NaN} or \code{Inf} (Fixing issue \ghit{16})
  }
}

\section{Changes in anytime version 0.0.4 (2016-10-20)}{
  \itemize{
    \item Before converting via \code{lexical_cast}, assign to atomic
    type via template logic to avoid an UBSAN issue (PR \ghpr{15}
    closing issue \ghit{14})
    \item More robust initialization and timezone information gathering.
    \item More robust processing of non-finite input also coping with
    non-finite values such as \code{NA}, \code{NaN} and \code{Inf} which
    all return \code{NA}
    \item Allow numeric \code{POSIXt} representation on input, also
    creating proper \code{POSIXct} (or, if requested, \code{Date})
  }
}

\section{Changes in anytime version 0.0.3 (2016-10-13)}{
  \itemize{
    \item Added (non-exported) helper function \code{testFormat()}
    \item Do not access \code{tm_isdst} on Windows for dates before the epoch
    (pull request \ghpr{13} fixing issue \ghit{12}); added test as well
  }
}

\section{Changes in anytime version 0.0.2 (2016-09-15)}{
  \itemize{
    \item Refactored to use a simple class wrapped around two vector
    with (string) formats and locales; this allow for adding formats;
    also adds accessor for formats (\ghpr{4}, closes \ghit{1} and
    \ghit{3}).
    \item New function \code{addFormats()} and \code{getFormats()}.
    \item Relaxed one tests which showed problems on some platforms.
    \item Added \code{as.POSIXlt()} step to \code{anydate()} ensuring
    all \code{POSIXlt} components are set (\ghpr{6} fixing \ghit{5}).
  }
}

\section{Changes in anytime version 0.0.1 (2016-09-12)}{
  \itemize{
    \item Initial release with \code{anytime()} and \code{anydate}
