Notable changes * performance: The performance of several APIs has been improved. - `Buffer.compare()` is up to 35% faster on average. (Brian White) #10927 - `buffer.toJSON()` is up to 2859% faster on average. (Brian White) #10895 - `fs.*statSync()` functions are now up to 9.3% faster on average. (Brian White) #11522 - `os.loadavg` is up to 151% faster. (Brian White) #11516 - `process.memoryUsage()` is up to 34% faster. (Brian White) #11497 - `querystring.unescape()` for `Buffer`s is 15% faster on average. (Brian White) #10837 - `querystring.stringify()` is up to 7.8% faster on average. (Brian White) #10852 - `querystring.parse()` is up to 21% faster on average. (Brian White) #10874 * IPC: - Batched writes have been enabled for process IPC on platforms that support Unix Domain Sockets. (Alexey Orlenko) #10677 - Performance gains may be up to 40% for some workloads. * child_process: - `spawnSync` now returns a null `status` when child is terminated by a signal. (cjihrig) #11288 - This fixes the behavior to act like `spawn()` does. * http: - Control characters are now always rejected when using `http.request()`. (Ben Noordhuis) #8923 - Debug messages have been added for cases when headers contain invalid values. (Evan Lucas) #9195 * node: - Heap statistics now support values larger than 4GB. (Ben Noordhuis) #10186 * timers: - Timer callbacks now always maintain order when interacting with domain error handling. (John Barboza) #10522 PR-URL: #11759
