2.0.0 Beta 5

• Improved UX of uncaught exceptions in child processes and task runs. The full stack trace in the context is displayed when converting the ContextPanicError or TaskFailureThrowable to a string, i.e., when the exception is uncaught in the parent and is written to STDERR
• Xdebug ini settings are forwarded to processes created by ProcessContext (including workers executing tasks), allowing step debugging through IDEs such as PhpStorm.
• Added an optional Cancellation argument to ProcessContext::start() and ContextFactory::start()
• Fix signals terminating child processes if a handler was not created in the child
• Updated for compatibility of 2.0 of amphp/socket
