+
+### BREAKING CHANGES
+
+- Snabbdom does not export the hero module any more. If you require this
+  module, copy the code from examples/hero/hero.js and add it to your
+  project
+- The imports of snabbdom functions have changed. Every file in the
+  project had to be imported on its own, e.g.
+
+```
+import { h } from 'snabbdom/h'
+import { VNode } from 'snabbdom/vnode'
+```
+
+Now, the main snabbdom package exports all of the public API like
+
+```
+import { h, VNode } from 'snabbdom'
+```
+
+This means consumers of the snabbdom package need to update their
+imports. The change makes the use of the `exports` field in
+`package.json` unnecessary, which caused issues for TypeScript users
+
