### Notable Changes

- **zlib**:
  - CVE-2017-14919 - In zlib v1.2.9, a change was made that causes an error to be raised when a raw deflate stream is initialized with windowBits set to 8. On some versions this crashes Node and you cannot recover from it, while on some versions it throws an exception. Node.js will now gracefully set windowBits to 9 replicating the legacy behavior to avoid a DOS vector. [nodejs-private/node-private#95](https://github.com/nodejs-private/node-private/pull/95)
