2019-08-20, Version 12.9.0 (Current)

Notable changes:

* **crypto**:
  * Added an oaepHash option to asymmetric encryption which allows users to specify a hash function when using OAEP padding (Tobias Nießen) [#28335](#28335).
* **deps**:
  * Updated V8 to 7.6.303.29 (Michaël Zasso) [#28955](#28955).
    * Improves the performance of various APIs such as `JSON.parse` and methods
      called on frozen arrays.
    * Adds the [`Promise.allSettled`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise/allSettled) method.
    * Improves support of `BigInt` in `Intl` methods.
    * For more information: https://v8.dev/blog/v8-release-76
  * Updated libuv to 1.31.0 (cjihrig) [#29070](#29070).
    * `UV_FS_O_FILEMAP` has been added for faster access to memory mapped files on Windows.
    * `uv_fs_mkdir()` now returns `UV_EINVAL` for invalid filenames on Windows. It previously returned `UV_ENOENT`.
    * The `uv_fs_statfs()` API has been added.
    * The `uv_os_environ()` and `uv_os_free_environ()` APIs have been added.
* **fs**:
  * Added `fs.writev` and `fs.writevSync` methods. They allow to write an array of `ArrayBufferView`s to a file descriptor (Anas Aboureada) [#25925](#25925).
* **http**:
  * Added three properties to `OutgoingMessage.prototype`: `writableObjectMode`, `writableLength` and `writableHighWaterMark` [#29018](#29018).
* **stream**:
  * Added an new property `writableEnded` to writable streams. Its value is set to `true` after `writable.end()` has been called. (Robert Nagy) [#28934](#28934).
