Breaking changes

Drop support for Node.js 6 (dce22670, #221)
Remove execa.shell() and execa.shellSync(). The shell option should be used instead. (#219)
Remove execa.stdout() and execa.stderr(). childProcessResult.stdout and childProcessResult.stderr should be used instead (#234)
Remove error.code (number or string) in favor of error.exitCode (number) and error.exitCodeName (string) (#187, #250)
Rename stripeEof option to stripFinalNewline (f8397ba9, 4d0dc88a, #238)
Rename cmd (in childProcessResult and error) to command (#194)
Default preferLocal option to false. If you are executing locally installed binaries, you'll need to manually specify preferLocal: true (#314)
Ensure windowsHide option is always true, so that no window pops up on Windows. (8c886452)
error.signal is now undefined instead of null when no signal was used (#193)
Set error.killed to false when child process timed out (#227)
Make error.killed always boolean (not undefined) (#229, #248)
Ensure errors always have the same shape. (#276, #277, #283)

Features

Add TypeScript definition (#188, f2cb86ff, 7702b8ef, 4692dcd4, #251)
Add execa.command() and execa.commandSync(). Those are the same as execa() except both file and arguments are specified in a single string. For example, execa('echo', ['unicorns']) is the same as execa.command('echo unicorns') (#182, #261, #262, #278, #279, #282)
Retrieve interleaved stdout and stderr with childProcess.all and childProcessResult.all (#171, #264)
Add execa.node() which (like child_process.fork()) allows you to execute a Node.js script as a child process (#200, #297, #299, #302, #303, #305, #306).
If childProcess.kill() does not terminate a child process after 5 seconds, force it by sending SIGKILL. This can be configured using the forceKillAfterTimeout option. (#208, #272, #273, #280, #284, #285)
Add childProcess.cancel() and error.isCanceled (#189, f24e7c72, #226, #309)
error.stdout, error.stderr and error.all now contain the data that was sent before the child process exit. (#271)
Improve error.message on child process failure (#180, #223, #230, #245, #269)
Add .finally() to the child process promise (#174, 65139849)
Increase maxBuffer option default value from 10 MB to 100 MB (#286)

Bug fixes

Fix timeout option not working as expected (#199)
Fix error.timedOut not working with execa.sync() (#249)
Fix maxBuffer errors not using the same shape as the other errors (#266)
Fix extendEnd option not working with shell option (#184)
Fix stripFinalNewline option not applied on error properties (#240)
Fix /q parameter not added when using cmd instead of cmd.exe (#203)
Fix uncaught exception when using input option with a non-executable file (#212, #258)
Fix errors on child processes waiting for stdout/stderr to complete (#270)
Fix validating that the stdio option cannot be used together with stdin: 0 (#301).
