-#### [BREAKING] Remove support for Flow comments (#13687, #13703 by @thorn0)
-
-Being a kind of preprocessor, [Flow comments](https://flow.org/blog/2015/02/20/Flow-Comments/) AKA [comment types](https://flow.org/en/docs/types/comments/) are processed on the token level and can't be represented in an AST in the general case. Flow builds the AST as if these special comment tokens didn't exist. Example:
-
-<!-- prettier-ignore -->
-```js
-/*:: if */ (x) + y;
-```
-
-This is parsed as `if (x) +y;` by Flow and as `x + y;` by JS parsers that don't support Flow.
-
-Previously, for some special cases, Prettier tried to detect that this syntax was used and to preserve it. As an attempt to solve an unsolvable problem, this limited support was fragile and riddled with bugs, so it has been removed. Now if the `parser` option is set to `flow` or `babel-flow`, Flow comments will be parsed and reprinted like normal code. If a parser that doesn't support Flow is used, they will be treated like usual comments.

-```js
-// Input
-let a /*: foo */ = b;
-
-// Prettier stable
-let a /*: foo */ = b;
-
-// Prettier main with --parser flow
-let a: foo = b;
-
-// Prettier main with --parser babel
-let a /*: foo */ = b;
