Use require_once when including php-resque after the app has been included in the sample resque.php to prevent include conflicts (andrewjshults)
Wrap job arguments in an array to improve compatibility with ruby resque (warezthebeef)

Trim output of ps to remove any prepended whitespace (KevBurnsJr)
Use getenv instead of $_ENV for better portability across PHP configurations (hobodave)
Add support for sub-second queue check intervals (KevBurnsJr)
Ability to specify a cluster/multiple redis servers and consistent hash between them (dceballos)
Change arguments for jobs to be an array as they're easier to work with in PHP.
Implement ability to have setUp and tearDown methods for jobs, called before and after every single run.
Fix APP_INCLUDE environment variable not loading correctly.
Jobs are no longer defined as static methods, and classes are instantiated first. This change is NOT backwards compatible and requires job classes are updated.
Job arguments are passed to the job class when it is instantiated, and are accessible by $this->args. This change will break existing job classes that rely on arguments that have not been updated.
Bundle sample script for managing php-resque instances using monit
Fix undefined variable $child when exiting on non-forking operating systems
Add PIDFILE environment variable to write out a PID for single running workers
