+The font contains the math table for constructing extensible arrow. However \texttt{unicode-math} does not privode an interface to that.

+\begin{verbatim}
+\usepackage{extarrow} %or mathtools
+\makeatletter
+\renewcommand{\relbar}{\symbol{"E010}\mkern-.2mu\symbol{"E010}\mkern1.8mu}
+\renewcommand{\Relbar}{\symbol{"E011}\mkern-.2mu\symbol{"E011}\mkern1.8mu}
+\makeatother
+\end{verbatim}
+Then \texttt{\textbackslash xleftarrow} and other commands will work:
+\[\mathrm{CH}_3\mathrm{COO}\mathrm{H}+\mathrm{C}_2\mathrm{H}_5\mathrm{OH}\xrightarrow[{\triangle}]{\mathrm{H}_2\mathrm{SO}_4}\mathrm{CH}_3\mathrm{COOC}_2\mathrm{H}_5+\mathrm{H}_2\mathrm{O}.\]
  
 \section{Known Issue}
 \begin{itemize}
-    \item As mentioned before, the font should only be used with \XeTeX.
-    \item Various spacing problems. Though math fonts technically should not be kerned, some pairs looks very ugly (Ex. $VA$); sometimes sub/superscript may also have same problem.
+    \item Various spacing problems. Though math fonts technically should not be kerned, some pairs looks very ugly (Ex. $VA$); sometimes sub/superscript may also have same problem. However, do note that due to the mechanism in math mode, making all spacing look perfect is amlost impossible (as far as I can do, and low x-height and large italic angle only make things even worse), in many cases, adjusting manually (i.e. using \texttt{\textbackslash,} or \texttt{\textbackslash!}) is required.
     \item Fake optical size. EB Garamond does not contain a complete set of glyphs (normal + bold + optical size of both weights). The ``optical size \texttt{ssty}'' is made by interpolating different weights at the present (without this, the double script is too thin to be readable).

 ## Notes
 
 - *Important notes for this version* 
-    - Fixed various wrong mappings, add italic h.var.
-    - Fraktur is (temporarily) not supported, Because (1) Originally they come from  [TeX Gyre Termes Math](http://www.gust.org.pl/projects/e-foundry/tg-math/) and GUST and OFL are not completely compatible; (2) The glyphs are not modified at all, so there is in principle no need to include it (one can use `range` option in `unicode-math`) 
-    - Default `\mathbb` is swapped with original `StylisticSet=1`.
-
-- *Blackboard* (`\mathbb`):
-    - Glyphs based on [XITS Math](https://github.com/khaledhosny/xits) are also available. However, the crossings and endpoints of strokes are rounded to fit the style of EB Garamond. They can be accessed via `StylisticSet=1`.
-
-- *Script* (`\mathscr`):
-    - Default glyphs are from XITS Math. The weight (especially for bold) and crossings and endpoints of strokes are modified.
-    - CM glyphs with a little modification are also available with `StylisticSet=3`
-
-- *Sans serif, typewriter*: from [Libertinus Math](https://github.com/khaledhosny/libertinus). This font has low x-height as Garamond do, though the bold italic Greeks are unavailable.
-
-- *Other glyphs available*: display `\int`, `\sum`, `\underbrace`, big delimiters, `\widehat`, arrows, binary relations derived, circled characters, etc, from the original EB Garamond.
+    - Massive metric adjustment. Now the metric is much closer to that of text.
+    - Now it should work with LuaTeX
+    - Added larger oprators etc;
+    - Reimport Fraktur from [Noto Sans Math](https://github.com/googlefonts/noto-fonts/).
 
 - Stylistic sets: (`StylisticSet={#1,#2,...}` in [`unicode-math`](https://ctan.org/pkg/unicode-math?lang=en) package)

 ## Known Issue
-- Currently only usable for `XeTeX` (with `unicode-math`). OTHER ENGINES (EX. `LuaTeX`, `MS Word`) WILL PRODUCE VERY BAD SPACINGS.
