+   \item Introduce pad mode.
-  \item Introduce \lstinline{chinesefont} option, with \lstinline{founder}, \lstinline{ctexfont} and \lstinline{nofont} available.
+   \item Support mtpro2 package.
-  \item Turn author information on the cover optional and add customized command \lstinline{\bioinfo}.
+   \item Revise default format of references to numbers.

+   \item Include environment for chapter introduction.
-  \item Add Chinese chapter style \lstinline{scheme} with option \lstinline{chinese}.

+   \item Include margin note using \lstinline{\elegantpar} (beta).
-  \item Drop \lstinline{\lastpage} from header to avoid page anchor bug and adding \lstinline{\frontmatter}.

 \begin{note}

Users for 2.x, please refer to \href{https://github.com/ElegantLaTeX/ElegantBook/wiki/convert}{conversion}.
+	Since the latest version has witnessed huge reconstruction (with cover change in version 3.06), 3.x is backward incompatible with 2.x.

-This template is based on the Standard \LaTeX{} book class, so the options of book class work as well (Note that the option of papersize has no effect due to \lstinline{device} option).

-\section{Math Fonts}
-This template defines a new command(\lstinline{math}), with three options:
-\begin{enumerate}
-  \item \lstinline{math=cm}(default), use \LaTeX{} default math font (recommended).
-  \item \lstinline{math=newtx}, use \lstinline{newtxmath} math font (may bring about bugs).
-  \item \lstinline{math=mtpro2}, use \lstinline{mtpro2} package to set math font.
-\end{enumerate}
-
-\section{Use newtx fonts}
-If you use \lstinline{newtx} fonts, type in:
-
-\begin{lstlisting}
-\documentclass[math=newtx]{elegantbook}
-\end{lstlisting}
-
-
-\subsection{Hyphens}
-Since the template uses \lstinline{newtx}, please pay attention to the hyphens. For instance,
-\begin{equation}
-\int_{R^q} f(x,y) dy.\emph{of\kern0pt f}
-\end{equation}
-
-The corresponding code is: 
-\begin{lstlisting}
-\begin{equation}
-\int_{R^q} f(x,y) dy.\emph{of \kern0pt f}
-\end{equation}
-\end{lstlisting}
-
-\section{Symbol Fonts}
-Feedback from some 3.08 users claims that error occurs when using our templates with  \lstinline{yhmath}, \lstinline{esvect} and other packages.
-\begin{lstlisting}
-LaTeX Error:
-Too many symbol fonts declared.
-\end{lstlisting}
-
-The reason is that the template redefines font for math so that no new math font is allowed to be added. To use \lstinline{yhmath} and/or \lstinline{esvect}, please locate \lstinline{yhmath} or \lstinline{esvect} in \lstinline{elegantbook.cls}, uncomment corresponding related code.

 Regression analysis is a powerful statistical method that allows you to examine the relationship between two or more variables of interest. While there are many types of regression analysis, at their core they all examine the influence of one or more independent variables on a dependent variable. The process of performing a regression allows you to confidently determine which factors matter most, which factors can be ignored, and how these factors influence each other.

+For version 3.08, we introduce margin note option and \lstinline{\elegantpar} (Beta). In this template, margin note option \lstinline{marginpar} is included. If \lstinline{marginpar=margintrue}, the width of both sides will reduce at least 1.5cm. If \lstinline{marginpar=marginfalse}, the width of sides will remain unchanged. Margin note option works under \lstinline{device=normal} only.
+
+Margin note option can be activated using \lstinline{\marginpar} built in \LaTeX{} or \lstinline{\marginnote} command in \lstinline{marginnote}. For more information, refer to \href{https://en.wikibooks.org/wiki/LaTeX/Footnotes_and_Margin_Notes#Margin_Notes}{Margin Notes} or \LaTeX{} books.

 \chapter{FAQ}
-We list some FAQs for users to refer to:
-\begin{enumerate}
-  \item \question{Why option numbers for natbib fail to take effect in v3.07?}
-  In v3.07, when \lstinline{gbt7714} is introduced, option \lstinline{authoryear} is incompatible with \lstinline{natbib}. In v3.08 and 3.09, \lstinline{numbers}, \lstinline{numbers}, \lstinline{super} and \lstinline{authoryear} are introduced.
-  \item \question{I want to customize font and background color.}
-  Please use \lstinline{pagecolor} to change background color, refer to \href{https://tex.stackexchange.com/questions/278544/xcolor-what-is-the-equivalent-of-default-text-color}{this} to customize font.
-  \item \question{Which version should I choose?}
-  Please use \href{https://github.com/ElegantLaTeX/ElegantBook/releases}{Latest Release} via GitHub or \TeX{} Live 2019.
-  \item \question{Which editor should I choose?}
-  You can use \TeX{} Live 2019 built-in \TeX works or \TeX Studio. You may refer to \href{https://github.com/EthanDeng/texworks-autocomplete}{\TeX{}works autocomplete}. \TeX{} Live 2019 + \TeX{}studio is strongly recommended. I myself use VS Code and Sublime Text. Related configurations can be found at \href{https://github.com/EthanDeng/vscode-latex}{vscode-latex} and \href{https://github.com/EthanDeng/sublime-text-latex}{sublime-text-latex}.

-  Feel free to use our templates by pointing out our copyright. For other issues, please refer to LPPL-1.3c. If you want to show us your work, share the URL with us afterwards.
-  \item \question{What is cross reference?}
-  This template is aimed at who are not a complete beginner for \LaTeX{}. Please learn more about \LaTeX{} before using this template.
-  \item \question{Is the language for code highlighting optional?}
-  Yes, \lstinline{listings} package is used in ElegantBook, hence language is optional(e.g. \lstinline{language=Python}). For global setting, use \lstinline{lstset}. For more information, please refer to package documentations.
-  \item \question{When will Beamer template (ElegantSlide or ElegantBeamer) forthcoming?}
-  Since there is an excellent theme \href{https://github.com/matze/mtheme}{Metropolis}, a Beta theme PreElegantSlide is available in QQ group. Feel free to download. A formal version is forthcoming in this year or next year.

 \chapter{Mathematical Tools}
 
 This appendix covers some of the basic mathematics used in econometrics. We briefly discuss the properties of summation operators, study the properties of linear and some nonlinear equations, and review the ratios and percentages. We also introduce some special functions that are common in econometrics applications, including quadratic functions and natural logarithms. The first four sections require only basic algebraic techniques. The fifth section briefly reviews differential Calculus Although Calculus is not necessary to understand much of this book, it is used in some of the end-of-chapter appendices and in some of the more advanced topics in part 3.
