@@ -340,8 +346,10 @@ # MobX 4 vs MobX 5

The most noteable limitations of MobX 4:
* Observable arrays are not real arrays, so they won't pass the `Array.isArray()` check. The practical consequence is that you often need to `.slice()` the array first (to get a real array shallow copy) before passing to third party libraries.
* Adding properties to existing observable objects after creation is not automatically picked up. Instead, either use observable maps or use the the built-in [utility functions](https://mobx.js.org/refguide/object-api.html) to read / write / iterate objects that you want to dynamically add properties to.

## Flow support
MobX ships with [flow typings](flow-typed/mobx.js). Flow will automatically include them when you import MobX modules. Although you **do not** need to import the types explicitly, you can still do it like this: `import type { ... } from 'mobx'`.
