2016-10-12, Version 6.8.0 (Current)

* fs:
  - `SyncWriteStream` now inherits from `Stream.Writable`. (Anna
Henningsen) nodejs#8830
    - Practically, this means that when stdio is piped to a file,
stdout and stderr will still be `Writable` streams.
  - `fs.existsSync()` has been undeprecated. `fs.exists()` remains
deprecated. (Dan Fabulich) nodejs#8364
* http: `http.request()` now accepts a `timeout` option. (Rene Weber)
nodejs#8101
* module: The module loader now maintains its own realpath cache. (Anna
Henningsen) nodejs#8100
* npm: Upgraded to 3.10.8 (Kat Marchán)
nodejs#8706
* stream: `Duplex` streams now show proper `instanceof
Stream.Writable`. (Anna Henningsen)
nodejs#8834
* timers: Improved `setTimeout`/`Interval` performance by up to 22%.
(Brian White) nodejs#8661
