This release might move some imported items with type around. This is a breaking formatting change (that only affects TypeScript and Flow), but only in the form of that you need to autofix your files.

In previous versions, type specifiers came first:

import { type B, a } from "a";
export { type B, a } from "a";

Now, all specifiers are sorted alphabetically, regardless of type:

import { a, type B } from "a";
export { a, type B } from "a";

Motivation:

You might import a class for a type annotation using:

import {
  type MyClass,
  coolFunction,
} from "example";

Later, you also start instantiating that class in the same file (new MyClass()), so you remove type.

Previously, this resulted in a messy diff due to the class moving:

 import {
-  type MyClass,
   coolFunction,
+  MyClass,
 } from "example";

Now, the sorting with the type keyword would be:

import {
  coolFunction,
  type MyClass,
} from "example";

Now there’s no reordering diff, just the type keyword being removed:

 import {
   coolFunction,
-   type MyClass,
+   MyClass,
 } from "example";

This is consistent with [“Why sort on from?”][sort-from].
