### Notable changes

- **child_process**: `send()` now accepts an options parameter (cjihrig) [#5283](https://github.com/nodejs/node/pull/5283).
  - Currently the only option is `keepOpen`, which keeps the underlying socket open after the message is sent.
- **constants**: `ENGINE_METHOD_RSA` is now correctly exposed (Sam Roberts) [#5463](https://github.com/nodejs/node/pull/5463).
- Fixed two regressions which originated in v5.7.0:
  - **http**: Errors inside of http client callbacks now propagate correctly (Trevor Norris) [#5591](https://github.com/nodejs/node/pull/5591).
  - **path**: Fixed normalization of absolute paths (Evan Lucas) [#5589](https://github.com/nodejs/node/pull/5589).
- **repl**: `start()` no longer requires an options parameter (cjihrig) [#5388](https://github.com/nodejs/node/pull/5388).
- **util**: Improved `format()` performance 50-300% (Evan Lucas) [#5360](https://github.com/nodejs/node/pull/5360).
