\section{Changes in version 4.1.1}{

  \subsection{NEW FEATURES}{
    \itemize{
      \item{
        Default proposals for \code{\link[=Binomial-ergmReference]{Binomial}}, \code{\link[=Poisson-ergmReference]{Poisson}}, \code{\link[=Geometric-ergmReference]{Geometric}}, and also \code{\link[=DiscUnif-ergmReference]{DiscUnif}} now implement the full DyadGen API for arbitrary dyad-level constraint combinations and TNT proposal weighting.
      }
    }
  }


  \subsection{BUG FIXES}{
    \itemize{
      \item{
        Vignette's run time is now more predictable.
      }
      \item{
        Miscellaneous documentation fixes.
      }
    }
  }


  \subsection{OTHER USER-VISIBLE CHANGES}{
    \itemize{
      \item{
        Term and termalike documentation has been ported to the new documentation system.
      }
      \item{
        Package tests now use \pkg{testthat}.
      }
      \item{
        Proposals \code{Poisson}, \code{PoissonTNT}, \code{PoissonNonObserved}, \code{Geometric}, \code{GeometricTNT}, \code{Binomial}, and \code{BinomialTNT} have been removed in favour of the more universal \code{\link[=Disc-ergmProposal]{Disc}} and \code{\link[=DiscTNT-ergmProposal]{DiscTNT}} for random and TNT weights.
      }
    }
  }
}


\section{Changes in version 4.0.2}{

  \subsection{NEW FEATURES}{
    \itemize{
      \item{
        A vignette demonstrating the package's functionality has been added.
      }
    }
  }

  
  \subsection{BUG FIXES}{
    \itemize{
      \item{
        Package now uses the \code{\link[ergm:ergm-package]{ergm}} 4.0 term API, which should result in a nontrivial speedup.
      }
    }
  }
}


\section{Changes in version 3.4.0}{

  \subsection{BUG FIXES}{
    \itemize{

      \item Package has been ported to the \code{\link[ergm-package]{ergm}} 3.10 API changes.

    }
  }

  \subsection{OTHER USER-VISIBLE CHANGES}{
    \itemize{

      \item Package now Imports \code{statnet.common} rather than depending on it.

    }
  }

}


\section{Changes in version 3.3.0}{

  \subsection{BUG FIXES}{
    \itemize{
      \item Package now works when loaded but not attached.
      \item Test that was failing with \code{\link[ergm-package]{ergm}}
      3.6.0 has been fixed.
    }
  }
}


\section{Changes in version 3.2}{

  \subsection{NEW FEATURES}{
    \itemize{
      \item \code{ergm.count} now makes use of contrastive divergence in
      \code{\link[=ergm:ergm-package]{ergm}} to obtain starting values for
      the MCMLE.

      \item Poisson-reference ERGMs now have TNT-style proposal,
      optimized for sparse networks.
    }
  }

  \subsection{OTHER USER-VISIBLE CHANGES}{
    \itemize{
      \item The \code{\link{CMP}} term now adds, rather than subtracts
      \eqn{\sum_{(i,j)}\log(y_{i,j}!)}, whereas 3.1.1 and prior versions
      did the opposite. This means that higher
      \eqn{\theta_{\text{CMP}}} represents overdispersion and lower
      \eqn{\theta_{\text{CMP}}} represents underdispersion.
    }
  }
}


\section{Changes in version 3.1.1}{

  \subsection{OTHER USER-VISIBLE CHANGES}{
    \itemize{
      \item E-mail address and affiliation of the maintainer have been updated.
    }
  }

}


\section{Changes in version 3.1}{

  \subsection{THIS IS AN INITIAL RELEASE}{
    \itemize{
      \item Although this is an initial release, it is depends very heavily on
      the \code{\link[=ergm-package]{ergm}} package version 3.1, and it is
      thus numbered 3.1.
    }
  }

  \subsection{NEW FEATURES}{
    \itemize{
      \item A number of reference measures for count data have been
      implemented. See \code{? 'ergm.count-package'} and \code{? 'ergm-references'} for help.
    }
