#### Markdown: Preserve single tildes in Markdown ([#19739](https://github.com/prettier/prettier/pull/19739) by [@lazerg](https://github.com/lazerg))
Since 3.9.0, single-tilde spans like `H~2~O` were rewritten to double tildes, turning subscript syntax into strike-through. Only double tildes are treated that way now, matching GitHub.

#### Markdown: Strip blockquote markers from a setext heading's continuation lines ([#19878](https://github.com/prettier/prettier/pull/19878) by [@Kjubikstronk](https://github.com/Kjubikstronk))
A setext heading spanning multiple lines inside a blockquote kept the `>` marker of its continuation lines as literal text.
