A major feature release with some minor API improvements! This project now has limited Windows support and supports passing custom pipes and file descriptors to the child process.

This update involves a few minor BC breaks. We've tried hard to avoid BC breaks where possible and minimize impact otherwise. We expect that most consumers of this package will actually not be affected by any BC breaks, see below for more details.

• Feature / BC break: Support passing custom pipes and file descriptors to child process, expose all standard I/O pipes in an array and remove unused Windows-only options. (#62, #64 and #65 by @clue)

  BC note: The optional $options parameter in the Process constructor has been removed and a new $fds parameter has been added instead. The previous $options parameter was Windows-only, available options were not documented or referenced anywhere else in this library, so its actual impact is expected to be relatively small. See the documentation and the following changelog entry if you're looking for Windows support.

• Feature: Support spawning child process on Windows without process I/O pipes. (#67 by @clue)

• Feature / BC break: Improve sigchild compatibility and support explicit configuration. (#63 by @clue)

  // advanced: not recommended by default
  Process::setSigchildEnabled(true);
  

  BC note: The old public sigchild methods have been removed, but its practical impact is believed to be relatively small due to the automatic detection.

• Improve performance by prefixing all global functions calls with \ to skip the look up and resolve process and go straight to the global function. (#68 by @WyriHaximus)

• Minor documentation improvements and docblock updates. (#59 by @iamluc and #69 by @CharlotteDunois)

• Improve test suite to test against PHP7.2 and PHP 7.3, improve HHVM compatibility, add forward compatibility with PHPUnit 7 and run tests on Windows via Travis CI. (#66 and #71 by @clue)
