  \itemize{
    \item{This version represents a major revision in that the facilities for employing information criteria (AIC and BIC) have been considerabley expanded. The infoCriteria method has been modified to add the possibility of calculating not only the the information criteria based on the REML likelihood, but those based on the full likelihood instead. There are now two infoCriteria methods, one for \code{asreml} objects and the other for \code{list}s of \code{asreml} objects. An alternative is to use changeTerms.asrtests wiith \code{IClikelihood} set to \code{REML} or \code{full} and the information criteria will be included in the The \code{test.summary} of the \code{asrtest} object. A new function changeModelOnIC has been included to allow model selection to be based on the information criteria, rather than on hypothesis tests. However, the two methods of selecting models can be interweaved.}

  \itemize{
    \item{Modify varofaces.asreml and simulate.asreml to perform the simulations and analysis of data sets using parallel processng.}

    \item{Add arguments \code{DF} and \code{bound.exclusions} to REMLRT.asreml and infoCriteria.asreml to allow more control over how the DF are determined. The number of bound parameters was added to the data.frame produced by these methods. Also, the arguments \code{bound.exclusions} and \code{REMLDF} were added to the methods testranfix.asrtests, testresidual.asrtests and testswapran.asrtests. }
    \item{Added \code{meanLSD.type} to allDifferences.data.frame, predictPlus.asreml and predictPresent.asreml to provide for an overall or per-prediction meanLSD. Allow \code{avsed.tolerance} in predictPlus to be set to \code{NA} which forces the calculation of LSDs for the overall mean LSD and set calculations of per-prediction LSDs whatever the value of code{avsed.tolerance}. Changed to calculate the mean SED to be used for an LSD as the square root of the mean(s) of the variances of pairwise differences.}
    \item{Added functions plotPvalues.data.frame and plotPvalues.alldiffs to plot heat maps of p-values for pairwise differences between predictions.}
    \item{Added function estimateV.asreml to form the estimated variance matrix for the observations. However, this function is not available in ASReml-R version 3.}

\section{Changes in asremlPlus Version 4.0-0 (2017-1-1)}{
  The asremlPlus version 4.x package represents a major revamp of asremlPlus to make it compatible with ASReml-R version 4 and, at the same time, to make the functions that operate on \code{asreml}, \code{asrtests} and \code{alldiffs} objects into S3 methods for these S3 objects. This means that
  \itemize{
    \item{The function names have been modified so that the only period (`.') in the name is that before the object type for which the function is a method;}
    \item{The object part of the function name is no longer needed when calling the function;}
    \item{The arguments had to be reordered for some functions so that the argument for the object for which it is a method is the first argument; this may cause problems if matching of arguments by position has been used in calling functions;}
    \item{The names of some arguments have been changed because of changes in ASReml-R version 4; for example, \code{rcov} has been changed to \code{residual} throughout.} 
}    

The full set of changes to function names is detailed in the asremlPlus manual and can be accessed using \code{?`asremlPlus-deprecated`}.

In spite of th changes, the new version still works with ASReml-R version 3, although with changes. A particularly problematic change for version 3 is that testrcov.asrtests becomes testresidual.asrtests even though \code{rcov} is still used in calls to \code{asreml}.
