\section{Changes in version 1.5.0 2020-10-29}{
\itemize{
\item Fix for CRAN issue concerning deprecated autoconf macros.
\item Updated invalid URLs.
\item Removed functions \code{readCopySolCPLEX}, \code{refineConflictCPLEX}, and \code{refineMipStartConflict}, because corresponding functions \code{CPXreadcopysol}, \code{CPXrefineconflictcplex}, and \code{CPXrefinemipstartconflict} were deprecated in Version >= 20.1.0.
\item Added function \code{readCopyStartInfoCPLEX} if building package with CPLEX Version >= 20.1.0.
\item Adaptation of Makevars.win to work with CPLEX version 20.1.0.
}
}
% ---------------------------------------------------------------------------- %
\section{Changes in version 1.4.1 2020-09-22}{
\itemize{
\item Adaptation of configure script to guess CPLEX installation directory on Mac OS, if neither environment variables
PKG_CPPFLAGS and PKG_LIBS, nor configure arguments --with-cplex-include and --with-cplex-lib are given, and option
--with-cplex-dir was not given and respective directory could not be extracted from the path variable.
\item Small change in INSTALL file according to Mac OS installation information.
}
}
% ---------------------------------------------------------------------------- %
\section{Changes in version 1.4.0 2020-09-17}{
\itemize{
\item Removed function \code{copyPartBaseCPLEX}, because corresponding CPLEX function \code{CPXcopypartialbase} was removed in CPLEX
Version >= 12.10.0.
\item Adaptation of configure script to extract correct linker options from example Makefile in CPLEX versions >= 10.9.0,
if neither environment variables PKG_CPPFLAGS and PKG_LIBS, nor configure arguments --with-cplex-include and --with-cplex-lib are given,
and option --with-cplex-dir was given or the respective directory could be extracted from the path variable.
\item Adaptation of configure script to allow more flexibility in specifying the CPLEX installation directory with option --with-cplex-dir.
\item Adaptation of Makevars.win to work with CPLEX version 12.10.0.
\item According to a comment from Daniel Junglas, CPLEX functions \code{CPXinitialize} and \code{CPXfinalize} should be called when the
shared library is loaded and unloaded to prevent subtle bugs. \code{CPXinitialize} is now called within cplexAPI's \code{.onload()} hook.
CPXfinalize() is called via a finalizer of the namespace:cplexAPI environment.
\item Small correction in INSTALL file to give the correct information for Windows installation.

\section{Changes in version 1.3.6 2019-06-21}{
\itemize{
\item Added functions \code{setLogFileNameCPLEX} and \code{getLogFileName} for interfacing CPLEX functions \code{CPXsetlogfilename} and
\code{CPXgetlogfilename} if building package with CPLEX Version >= 12.8.0.
\item Added funtion \code{getParmHierNameCPLEX} for interfacing CPLEX funtion \code{CPXgetparamhiername} if building with CPLEX Version 12.9.0.
\item Interface Functions \code{openFileCPLEX}, \code{closeFileCPLEX}, \code{addFpDestCPLEX}, \code{delFpDestCPLEX}, \code{fileputCPLEX},
\code{setLogFileCPLEX}, and \code{getLogFileCPLEX} will have no functionality and return NULL, if building with CPLEX version >= 12.9.0,
because related CPLEX functions \code{CPXfopen}, \code{CPXfclose}, \code{CPXaddfpdest}, \code{CPXdelfpdest}, \code{CPXfputs}, \code{CPXsetlogfile},
and \code{CPXgetlogfile} had been removed in CPLEX Version >= 12.9.0. For using logfiles, use \code{setLogFileNameCPLEX} and \code{getLogFileName}
instead.
