To change a file over from v2.x to run with v3.1, you need to make the
following changes. If you have a file formatted with version 1.x, first
delete the optional arguments to the \bibitem commands. That is,
\bibitem[1]{firstref} would become \bibitem{firstref}, etc.
Then make the following changes.
\documentstyle[revtex]{aps}
becomes
\documentstyle[aps]{revtex}
The preprint and eqsecnum options work the same as before.
\tightenlinesbecomes
\tighten
$\alt$ and $\agt$become
$\lesssim$ and $\gtrsim$
\begin{title}
XXX
\end{title}
becomes
\title{XXX}
\begin{instit}
XXX
\end{instit}
becomes
\address{XXX}
\receipt{XXX}
becomes
\date{XXX}
\maketitle should be added just before the \begin{abstract}
command is entered.
\figure{XXX\label{YYY}}
becomes
\begin{figure}
\caption{XXX\label{YYY}}
\end{figure}
Tablenotes should be converted over to run correctly. The first three
\tablenotes{#1} commands would be treated as follows:
\tablenotes{$^{\rm a}$Tablenote a.}
\tablenotes{$^{\rm b}$Tablenote b.}
\tablenotes{$^{\rm c}$Tablenote c.}
becomes
\tablenotetext[1]{Tablenote a.}
\tablenotetext[2]{Tablenote b.}
\tablenotetext[3]{Tablenote c.}
Further tablenotes should be treated similarly.
This should allow older tables to run correctly. There is much greater
capability in the new tablenote macros, however. See apssamp.tex for
examples and explanations.
\nonum\section{XXX}
becomes
\section*{XXX}
Note that there should only be one \unletteredappendix
command in any file.
\unletteredappendix{XXX}
becomes
\appendix
\section*{XXX}
Note that there may be more than one \appendix
command in any file. The first occurrence should be treated as follows:
\appendix{XXX}
becomes
\appendix
\section{XXX}
Subsequent occurrences should be treated as follows:
\appendix{XXX}
becomes
\section{XXX}
