* feat: implement \relax as no-op function BREAKING CHANGE: `\relax` is now implemented as a function. It'll stop expansions and parsing, so the behavior around `\relax` may change. For example, `\kern2\relax em` will no longer work.

v0.15.0
\relax is now implemented as a function. It'll stop expansions and parsing,
so the behavior around \relax may change. For example, \kern2\relax em will
no longer work.
v0.14.0
With module loaders that support conditional exports and ECMAScript modules,
import katex from 'katex'; will import the ECMAScript module.
You can now use:
| Before | After |
|---|---|
require('katex/dist/contrib/[name].js') |
require('katex/contrib/[name]') |
import katex from 'katex/dist/katex.mjs' |
import katex from 'katex' |
import 'katex/dist/contrib/[name].mjs' |
import 'katex/contrib/[name]' |
v0.13.0
Macro arguments
Tokens will not be expanded while parsing a macro argument. For example, \frac\foo\foo,
where the \foo is defined as 12, will be parsed as \frac{12}{12}, not
\frac{1}{2}12. To expand the argument before parsing, \expandafter can
be used like \expandafter\frac\foo\foo.
\def
\def no longer accepts a control sequence enclosed in braces. For example,
\def{\foo}{} no longer works and should be changed to \def\foo{}.
It also no longer accepts replacement text not enclosed in braces. For example,
\def\foo1 no longer works and should be changed to \def\foo{1}.
\newline and \cr
\newline and \cr no longer takes an optional size argument. To specify vertical
spacing, \\ should be used.
\cfrac, \color, \textcolor, \colorbox, \fcolorbox
They are no longer allowed as an argument to primitive commands, such as \sqrt
(without the optional argument) and super/subscript. For example,
\sqrt\textcolor{red}{x} no longer works and should be changed to
\sqrt{\textcolor{red}{x}}.
