+## New
+
+### Code Block Math
+
+You enable `Code Block Math` in `Preferences Panel` → `Markdown` → `Code Block Math` to enable support for Gitlab / GitHub style math block (<https://docs.gitlab.com/ee/user/markdown.html#math>) with following syntax:
+
+~~~gfm
+```math
+x = {-b \pm \sqrt{b^2-4ac} \over 2a}
+```
+~~~
+
+It renders as:

+
+Please note that Typora also support inline math like `$a+b$` and math block like:
+
+~~~gfm
+$$
+a+b
+$$
+~~~
+
+## Improvements
+
+### EPub Export
+
+Epub export now adds a "Chapter Level in Outline" option, you could now specify the number of section levels to include in the table of contents. The default is 3 (which means that level-1, 2, and 3 headings will be listed in the contents).

+
+### Block Diagram
+
+Mermaid library is now upgrade to version 10.9, which introduces a new Block Diagrams.

+For more details, [please click here](https://mermaid.js.org/syntax/block.html).
+
+### Header Anchor Spec
+
+For a bookmark link to a heading in the *current* file, use a hash symbol followed by the lowercase words of the heading. Remove punctuation from the heading and replace spaces with dashes. 
+
+Previously Typora will remove most western punctuation, while remains some Unicode punctuation, now Typora will follow following spec:
+
+```
+convert heading string to lowercase words
+keep - (hyphen)
+replace whitespace with - (hyphen)
+convert en dash to -- 
+convert em hash to ---
+remove other punctuation 
+```
+
