\section{CHANGES IN \pkg{expint} VERSION 0.1-7}{
  \subsection{BUG FIXES}{
    \itemize{
      \item{Replace deprecated (as of R 4.2.0) macro \code{DOUBLE_EPS} by
	\code{DBL_EPSILON} in C code.}
      \item{Remove the unnecessary \code{LazyData} entry in the
	\code{DESCRIPTION} file.}
    }
  }
}

\section{CHANGES IN \pkg{expint} VERSION 0.1-6}{
  \itemize{
    \item{Fixed the example API and the documentation in the vignette.
      The previous implementation yielded duplicated symbols with option
      \code{-fno-common} that will be the default in gcc starting with
      version 10.0.x. Thanks to Joshua Ulrich
      \email{josh.m.ulrich@gmail.com}, maintainer of 
      \pkg{xts} and \pkg{TTR} for proposing the fix.}

\section{CHANGES IN \pkg{expint} VERSION 0.1-5}{
  \itemize{
    \item{Minor documentation and comments updates.}
  }
}

\section{CHANGES IN \pkg{expint} VERSION 0.1-4}{
  \subsection{BUG FIX}{
    \itemize{
      \item{Usage of \code{R_useDynamicSymbols} to preclude compilation
	\code{NOTE}s, better registration of native routines and reduced
	symbol visibility.}
      \item{Vignette no longer uses LaTeX package framed as it was not
	found on OS X in CRAN builds.} 
    }
  }

\section{CHANGES IN \pkg{expint} VERSION 0.1-3}{
  \subsection{BUG FIX}{
    \itemize{
      \item{Fixed wrong values for expint_E1(x, scale = TRUE) for x in
	(-4, -1] or x in (0, 1]. Thanks to Vincent Dorie
	\email{vjd4@nyu.edu} for the catch and report.}
    }

\section{CHANGES IN \pkg{expint} VERSION 0.1-2}{
  \itemize{
    \item{Yet more authors (actually copyright holders) added to the
      list of authors.}
  }
}

\section{CHANGES IN \pkg{expint} VERSION 0.1-1}{
  \subsection{BUG FIX}{
    \itemize{
      \item{Fixed improper use of macro \code{ISNAN} (and \code{ISNA})
	that caused compilation to fail on Linux and Solaris.}

  }
  \subsection{OTHER CHANGES}{
    \itemize{
      \item{Original author of GSL code for \code{expint} and
	\code{gamma_inc} (G. Jungman) added as an author of the
	package.}
      \item{Improved (read: more explicit) copyright notices to GSL,
	R Core Team and R Foundation where appropriate.}
    }
  }

\section{CHANGES IN \pkg{expint} VERSION 0.1-0}{
  \itemize{
    \item{Initial release. The package provides the \R functions to compute
      the exponential integrals \eqn{E_1(x)}, \eqn{E_2(x)}, \eqn{E_n(x)}
      and \eqn{Ei(x)}, and the incomplete gamma function \eqn{G(a, x)}.
      The package also provides a C API to access the actual workhorses
      \code{expint_E1}, \code{expint_E2}, \code{expint_En} and
      \code{gamma_inc}. Sub-directory \file{example_API} of the package
      installation directory contains a complete test package
      implementing API usage.}
