## Updates

**July 16, 2021.** We introduce lazy LaTeX render. Now, when you open a page with new formulas, it uploads instantly and then formulas start rendering in front of your eyes. This way, we can avoid server overload and make pages open faster even if they have thousands of formulas. In particular, it means that the preview works very fast: the page opens immediately and then starts rendering all the formulas from the page.

The formulas are rendered in the following order: environments (equation, align, …), displayed ($$ … $$ and \[ … \]), inline ($ … $ and \( … \) ).

**June 23, 2021. **Finally, we support global page-wide preambles for QuickLaTeX! You can define your favorite commands, packages, and operators at the beginning of your post and use them page-wide.

```
[preamble]
\usepackage{eucal}
\newcommand{\OO}{\mathcal{O}} % The integer ring.
\newcommand{\p}{\mathfrak{p}} % The maximal ideal.
\newcommand{\Z}{\mathbb{Z}} % The integers.
\newcommand{\N}{\mathbb{N}} % The nonnegative integers.
\newcommand{\R}{\mathbb{R}} % The reals.
\newcommand{\C}{\mathbb{C}} % The complex numbers.
\DeclareMathOperator{\Ind}{Ind}
\DeclareMathOperator{\SL}{SL}
\DeclareMathOperator{\GL}{GL}
[/preamble]
```

**June 11, 2021. **We now support the following packages by default:

- amsmath
- amsfonts
- amssymb
- enumitem
- mathrsfs
- mathtools
- stmaryrd
- upgreek
- tikz-cd

Now you can easily write commutative diagrams! For example, ```
$$\begin{tikzcd}
A \ar{r} \ar{d} & B \ar{d} \\
C \ar{r} & D
\end{tikzcd}$$
```
