2019-06-04, Version 12.4.0 (Current)v12.4.0

Notable changes:

* doc:
  * The JSON variant of the API documentation is no longer experimental
    (Rich Trott) https://github.com/nodejs/node/pull/27842.
* esm:
  * JSON module support is always enabled under
    `--experimental-modules`. The `--experimental-json-modules` flag
    has been removed (Myles Borins)
    https://github.com/nodejs/node/pull/27752.
* http,http2:
  * A new flag has been added for overriding the default HTTP server
    socket timeout (which is two minutes). Pass
    `--http-server-default-timeout=milliseconds`
    or `--http-server-default-timeout=0` to respectively change or
    disable the timeout. Starting with Node.js 13.0.0, the timeout will
    be disabled by default
    (Ali Ijaz Sheikh) https://github.com/nodejs/node/pull/27704.
* inspector:
  * Added an experimental `--heap-prof` flag to start the V8 heap
    profiler on startup and write the heap profile to disk before exit
    (Joyee Cheung) https://github.com/nodejs/node/pull/27596.
* stream:
  * The `readable.unshift()` method now correctly converts strings to
    buffers. Additionally, a new optional argument is accepted to
    specify the string's encoding, such as `'utf8'` or `'ascii'`
    (Marcos Casagrande) https://github.com/nodejs/node/pull/27194.
* v8:
  * The object returned by `v8.getHeapStatistics()` has two new
    properties: `number_of_native_contexts` and
    `number_of_detached_contexts` (Yuriy Vasiyarov)
    https://github.com/nodejs/node/pull/27933.
