  ####Change log####
 
+ v1.27 (2021/12/26):
+ - fix bug in captions that appeared in Jan. 2021 (code not uppercasing caption text)
+ - revise code to switch to grid-style author block through a single package option, \[grid\]; previous macros for grid-style remain active. 
+ - various code modifications to enable older LaTeX distributions to run this class. With pdfLaTeX, TeX Live 2016 or later should be used; with luaLaTeX, TeX Live 2021 or later should be used.
+ - eliminate use of \\entry{} with a single argument to produce subheadings in nomenclature; use \\EntryHeading{} instead. (**not backward compatible**)
+ - incorporate recent changes to LaTeX pdf management in relation to pdf-a color profile loading and recently deprecated \\pdfcatalog command
+ - minor edits in relation to url links
+ - minor edits to asmeconf.bst
+ - allow omission of affiliation superscript for single author or single institution
+ - other minor code clean up
+ 
  v1.26 (2021/02/20):
  - edit title and metadata
  - put real author's name ahead of placeholder names

 \section{Introduction}
-The \texttt{\href{https://ctan.org/pkg/asmeconf}{asmeconf}} class typesets papers with margins, fonts, headings, captions, and reference formats that follow the specifications for conference papers of the American Society of Mechanical Engineers (ASME). In contrast to older ASME \LaTeX\ templates, \texttt{asmeconf} will set internal and external hyperlinks, and the pdf file will contain bookmarks and metadata. Many other useful features have been incorporated. This class is not a publication of ASME, but the author has published in ASME conferences since 1983. 
 
-The \texttt{.tex} file may be written using standard \LaTeX\ commands, although some specific initial commands are needed to format the blocks containing the author[s], title, and abstract.  This class loads a number of other packages, all of which are contained in up-to-date versions of \href{https://www.tug.org/texlive/}{\TeX\ Live}, \href{http://www.tug.org/mactex/}{Mac\TeX}, and similar platforms. If you find that you are missing one of these packages, you may obtain it at no cost from CTAN (\href{http://ctan.org}{ctan.org}).

 \section{Introduction}
-The \texttt{asmeconf} class typesets papers with margins, fonts, headings, captions, and reference formats that follow the specifications for conference papers of the American Society of Mechanical Engineers (ASME). In contrast to older ASME \LaTeX\ templates, \texttt{asmeconf} will set internal and external hyperlinks, and the pdf file will contain bookmarks and metadata. Many other useful features have been incorporated. This class is not a publication of ASME, but the author has published in ASME conferences since 1983. 
 
-The \texttt{.tex} file may be written using standard \LaTeX\ commands, although some specific initial commands are needed to format the blocks containing the author[s], title, and abstract.  This class loads a number of other packages, all of which are contained in up-to-date versions of \href{https://www.tug.org/texlive/}{\TeX\ Live}, \href{http://www.tug.org/mactex/}{Mac\TeX}, and similar platforms. If you find that you are missing one of these packages, you may obtain it at no cost from CTAN (\href{http://ctan.org}{ctan.org}).

 ASME requires that section headings and captions be set in an uppercase, sans serif font.  The class will do this automatically.  You can place \verb|\cite{..}|, \verb|\ref{..}|, \verb|\label{..}|, and mathematics into headings and captions directly, as you would in the main text. Do not enclose them braces, e.g.\ \verb|{\cite{..}}|, which will cause errors. You can place \verb|\footnote{..}| into headings, but not into captions.\footnote{See \texttt{tex-stackexchange} for various approaches to footnotes in captions, if they seem necessary. For footnotes in tables, use the \texttt{tablefootnote} package.}\footnote{Sequential footnotes are automatically separated by a comma.}

 Simple mathematical expressions can be used in either captions or section headings. For a section heading that includes more complicated math (and macros), you may use the optional argument of \verb|\section[..]{..}| to create a pdf bookmark without losing characters or producing warnings or errors. See the \texttt{asmeconf-template.tex} source file for examples of this procedure. These bookmarks should usually be text expressions, although some math is supported.

 \begin{abstract}
-This paper is an example of using \texttt{asmeconf} with {\upshape\hologo{LuaLaTeX}} to solve an ODE initial value problem using a fourth-order Runge-Kutta method and to plot the result using \texttt{PGFPLOTS}. The use of a landscape figure is also illustrated. References are given for further reading.
