This is an alpha release for the upcoming 2.0.0.

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 windowsHide option to true. This ensures 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 and error.isCanceled always boolean (not undefined) (#229, #248)
Ensure errors always have the same shape. (#276, #277, #283)

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)
If childProcess.kill() does not terminate a child process after 5 seconds, force it by sending SIGKILL. This can be configured using the forceKillAftrerTimeout option. (#208, #272, #273, #280, #284, #285)
Add childProcess.cancel() and error.isCanceled (#189, f24e7c72, #226)
error.stdout, error.stderr and error.all now contain the data that was sent before the child process exit. (#271)
