+- **lerna's task runner for `lerna run` now depends on nx v17 instead of v16**
+
+`lerna run` gets to benefit from all of the further performance improvements in the nx v17 task runner behind scenes.

 - **`@lerna/child-process` is no longer a separately published package**
 
 Lerna is a monorepo management tool with versioning and publishing capabilities, it is not a child process manager. There are lots of good options out there in the ecosystem to help you with managing child processes in nodejs, and it does not really make sense to treat some of lerna's implementation details around child processes as if they were a public API. The package will be officially deprecated on npm in the future. You can of course take the code and fork it and adapt it for your own purposes if you wish!
