+# 0.9.0
+
+* **BREAKING** Removed `applyPatches` and `applyActions`. Use `applyPatch` resp. `applyAction`, as both will now also accept an array as argument
+* **BREAKING** `unprotect` and `protect` can only be applied at root nodes to avoid confusing scenarios Fixed [#180](https://github.com/mobxjs/mobx-state-tree/issues/180)
+* Fixed [#141](https://github.com/mobxjs/mobx-state-tree/issues/141), actions / views are no longer wrapped in dynamically generated functions for a better debugging experience
+* Small improvements to typings, fixed compilation issues with TypeScript 2.4.1.
+* Fixed issues where `compose` couldn't overwrite getters. [#209](https://github.com/mobxjs/mobx-state-tree/issues/209), by @homura
+* Fixed CDN links in readme
+* Added TodoMVC to the examples section
+
+# 0.8.2
+
+* Fixed issue in rollup module bundle

- * TODO: update docs
- * Registers middleware on a model instance that is invoked whenever one of it's actions is called, or an action on one of it's children.
- * Will only be invoked on 'root' actions, not on actions called from existing actions.
- *
- * The callback receives two parameter: the `action` parameter describes the action being invoked. The `next()` function can be used
- * to kick off the next middleware in the chain. Not invoking `next()` prevents the action from actually being executed!
- *
- * Action calls have the following signature:
- *
- * ```
- * export type IActionCall = {
- *    name: string;
- *    path?: string;
- *    args?: any[];
- * }
- * ```
- *
- * Example of a logging middleware:
- * ```
- * function logger(action, next) {
- *   console.dir(action)
- *   return next(action)
- * }
- *
- * onAction(myStore, logger)
- *
- * myStore.user.setAge(17)
- *
- * // emits:
- * {
- *    name: "setAge"
- *    path: "/user",
- *    args: [17]
- * }

Fixed alerts

Major refactor

Supply chain risk

Package has recently undergone a major refactor. It may be unstable or indicate significant internal changes. Use caution when updating to versions that include significant changes.

Found 1 instance in 1 package

Uses eval

Supply chain risk

Package uses dynamic code execution (e.g., eval()), which is a dangerous practice. This can prevent the code from running in certain environments and increases the risk that the code may contain exploits or malicious behavior.
