I figure HTML tag isn't be able to use after v3.0.0.

Markdown library has changed from marked to markdown by #1966. markdown package do sanitize HTML, and can't disable it.

Actually, the PR disable sanitize option is already sent by evilstreak/markdown-js#132 in many years ago. However, it's not merged yet.

Why don’t you use markdown format?

@kyoshidajp is correct - this is due to the change in Markdown parser and we don't expect to bring this back (as this was never the intended behavior).

Just use Markdown.
